    15.8.2 isn't released.

    This is a report from the developer forums where people are supposed to report these bugs.

    The second response in the thread is an Apple engineer acknowledging the bug, assigning a number, and asking the person to retest when new builds are available.

    If you only read the comments here you'd come away with a completely different impression of what's happening.

      I hope it does get fixed, but Apple actually has a bad track-record with another deprecated API, AppleAL (OpenAL). They broke it in a very interesting way in Tahoe where mono-channel audio on Aarch64 (not through Rosetta) did not play and it was broken through all the betas. I believe it actually may still be broken today. The workarounds were either mono-to-faux-stereo channel duplication or switch to openal-soft.

      OpenGL is an even bigger deal so I don't see a world where it doesn't get fixed, but I also thought exactly the same way with the previous issue. It seems that Apple does not have any older video games in their testing apparatus.

      Some references on the issue:

      15.8.2 isn't released, but the 15.8.2 release candidate clearly is. I don't think think it's that crazy for people to be at least somewhat concerned that a fairly common important library got broken a bugfix release to a maintenance update that came out a month ago for a major version that came out two years ago without anyone internal testing it before publishing the RC.

        > 15.8.2 isn't released, but the 15.8.2 release candidate clearly is

        That’s how release candidates work.

        The headline could have included RC to make it accurate. As submitted it’s pretty misleading.

      An Apple engineer acknowledged the bug? That comment reeks strongly of Claude. I have a feeling that somebody did not use their brain and the response is an auto-response by Claude. Also things like attaching a sysdiagnose is useless and is well known to be hoops Apple requires bug reporters to jump through with no benefit to either party.

      You also make it sound like the Apple engineer assigned the number but the number was auto-assigned when the bug report was filed. The same number was present in the first post so it could not have been assigned by the Apple engineer.

      As far as I can see the Apple engineer did nothing at all. The attitude of that Apple engineer is worse than staying silent on this bug.

        > The attitude of that Apple engineer is worse than staying silent on this bug.

        The Apple engineer opened the ticket which is how these bugs get prioritized and fixed.

        Staying silent or not responding would mean it doesn’t get fixed.

        • kccqzy 16 minutes ago
          The Apple engineer didn’t open the ticket. The original reporter did. Maybe you should look at the assigned number before jumping to defend Apple.

        As a former Apple SWE that has read innumerable sysdiagnose reports, this statement is bullshit.

        External bug reports very commonly have a variation of "THIS IS BROKEN YOU SUCK FIX THIS" as the main note. Even with a crash log attached that's not at all helpful. A sysdiagnose gives a state of the system the reporter has in front of them. You can't triage a bug with "FIX NOW" as the description.

        I know I know, Apple has infinity dollars and every SWE should just magically fix bugs without needing to triage them first. Every external bug reports very is also a special snowflake that deserves concierge VIP serve and a dedicated SWE team to fix.

        • kccqzy 5 minutes ago
          Did you read the bug report? This is not your garden variety THIS IS BROKEN YOU SUCK FIX THIS bug. It is respectful, it has a minimal reproducer, and it is communicated clearly. There’s no reason to stall it using the sysdiagnose requirement.

          And yes, this is not the first time I’ve seen Apple requiring sysdiagnose for an excellently written report. Even John Siracusa would get these sysdiagnose requests; it’s a stalling tactic being applied indiscriminately.

          If Apple cannot distinguish between an angry nontechnical user that SHOUTS IN UPPERCASE and a developer that communicates well, that’s Apple’s problem.

      The problem is that this is a well established pattern with this operating system:

      - A bug or regression is identified in a beta or release candidate. People quickly come to defend Apple saying it will surely get fixed.

      - The bug or regression is released. People quickly come to defend Apple saying it's not a big deal, there are workarounds, and it will probably get fixed.

      - The bug or regression is now the status quo. Why are you rehashing old news? Nobody cares, this impacts only 1% of people, you're imagining things, thread locked, user banned, et cetera.

      The time to complain loudly and broadly is _before_ the bug or regression becomes the new status quo for the platform.

      Thanks for the context, the state of HN has been quite sad in recent years, now people (hopefully, and not bots) read the title and then go on random anecdotes, dumb generalisations and awkward tangents.

        Especially on special internet forums, HN included, bots are generally paid for by professional influence campaigns so..

        Yeah..

        Whatever those AI's have to do to shape the conversation to get their message in, that's what they'll do. And that's going to sound pretty awkward to human ears.

    The general Apple software quality decline seems to be accelerating. We are in the thousand papercut stage where lots of small things just don’t work properly.

    One of my Macs has developed the most insane habit of losing audio output capability, and then tries to route it to another one - a feature I didn’t even know existed.

      I've been playing around with RealityKit (https://developer.apple.com/documentation/realitykit) lately, it's their SceneKit replacement (they deprecated it this year).

      On tvOS if a frame takes too long it just starts skipping frames and runs at 20 FPS. It won't recover after it happens. ThermalState is .nominal, so it's not that. There's also no way to just say "render as fast as possible" so you can measure performance, instead every device does throttling/pacing and it's completely opaque.

      Anyway, I've had a developer account for 10+ years, and run into stuff like this constantly where you just can't get things to work properly. The framework isn't used much, so it's probably just broken.

      I ported the game to SDL3/Zig and wouldn't you know it I can run continuously at 60 fps.. It's disappointing because I'm on board with targeting a single platform if I can utilize the hardware more effectively and make something special with it. But instead it's constantly an uphill battle of dealing with the opaqueness/brokenness of the platform. If I open a feedback request I'll probably just get told it's a bug, and maybe they fix it next WWDC.

      The general Apple software quality decline seems to be accelerating.

      The iPhone 18 Pro has been out exactly a month now and they still haven't pushed a fix for the popping/crackling speaker issue:

      https://www.macrumors.com/2026/09/29/iphone-18-pro-speaker-c...

      I still get crackling or popping many times a day.

      Also, the annoying render stutters during scrolling across many apps haven't been fixed since iOS 26 was introduced (they were probably there before, but Liquid Glass made it worse). Even the iPhone 18 Pro suffers from it (also checked on iPhone 17 Pro and iPhone Air).

      Meanwhile, my underpowered P10P with GrapheneOS renders scrolling super smoothly.

        My Nexus 5's "underwater" mic issue never got addressed. Wouldn't be surprised if the next thing iOS copies from Android is, "Audio bug that just never gets fixed."

      My Iphone has had some bugs in the last year that are so sloppy yet impactful its almost funny. About half the time im looking at my lock screen notifications, the screen will lock less than a second after touching the screen. I have had other issues as well, but for a company with so much money I expect a little more craftsmanship.

      I have had other issues as well but something that actively locks my phone while I am obviously using it is an extremely frustrating start to my day.

      • mosura 1 hour ago
        Yeah iOS is headed the same way.

        I now get stuck in the camera app half the time I try to use it, and other nonsense.

      • callc 1 hour ago
        Same here.

        IME on the lock screen I’ll be interacting with the media controls and the screen will just turn off, like I’m not doing any interaction.

        It’s funny how that basic of functionality is broken.

        • lynndotpy 52 minutes ago
          I really appreciate that I'm not the only one. Using Apple software is increasingly an experience in navigating a minefield of bizarre UX mistakes.

          The big concern for me is if I ever find myself in an emergency situation and I need to use my phone to contact someone. Apple's iPhone is so inconsistent and unreliable even in the best of conditions.

        That sounds right.

        Although so far I'm mostly happy with Apple products. Happier than with any Windows laptops.

        (But damn if I encounter a bug or an issue. Just reporting those have made hordes of Apple fans attack me, in response to a standard technical bug report.)

        • pjmlp 1 hour ago
          Youngsters have to understand that Apple's quality was so bad, not only did they fail to deliver in a few products with industry partners, the teams weren't even capable of writing a new operating system.

          Windows is also equally away from "3x Developers!" cry days.

      I genuinely have more issue with my audio peripherals (USB microphone, bluetooth earbuds) on the M4 Macbook that my work gave me than on my Arch Linux desktop. Around once a month the Macbook will inexplicably not be able to receive input from mic or output to my earbuds (or both!) despite the OS settings still showing the current input/output as selected correctly. Rebooting somehow fixes it, but I'm at a loss to understand how the computer/OS that costs thousands of dollars and is supposed to "just work" because of being completely designed by a single entity manages to struggle with this when the completely arbitrarily selected set of hardware and software components that I threw together for my desktop seem to never have any problem like this nowadays.

      The latest macOS, after a lot of praise, has proven to be really buggy to me. At least liquid glass only had poor readability, but now windows go missing/turn invisible almost daily and it’s getting seriously annoying.
      • mort96 1 hour ago
        It's so extremely buggy! I upgraded to Golden Gate early (tho after release) because everyone (including here) said it's so much better than Tahoe, but it has fixed no bugs which annoyed me with Tahoe and introduced so many new ones. Mission Control frequently switches to the wrong window (perfectly reproducible bugs which result in the wrong window coming forward). And in Mission Control, windows now overlap each other, are overlapped by the dock, and end up partially outside the screen, in ways they just never did in any earlier macOS release. The Launchpad replacement part of Spotlight in 26 was always super buggy but has gotten even more buggy in 27. Just yesterday the WiFi menu in the menu bar beach balled.

        iOS text input is also super buggy now, with frequent rendering glitches where the new blue words from "AI" suggestions or whatever overlap other text, there are stale blue squiggles which are hold-overs from grammatical issues which have since been fixed, completely nonsensical grammatically nonsense suggestions, etc.

        The decrease in quality from 15 to 26 and then 26 to 27 is staggering.

      Audio problems aren't new. I remember that the last 10.9 build I was still using in 2016 had this bug where sound would just stop working every now and then. `sudo pkill coreaudiod` fixed it every time.

      My personal favorite is the alarm clock on iOS, after the first time you dismiss the alert with the phone unlocked, it reappears as a transparent dialog 10% of the size of a normal one (i.e. so small not even a stylus could click the buttons). The mashed ball of widgets can only be swiped off the screen.

        This bug is one of many papercuts in Apple software.

        Here’s another: Hide My Email’s “Forward To” feature is broken. You can’t change which email address messages get forwarded to. I have nearly 500 Hide My Email addresses and want to change the forwarding address, but can’t because the feature is broken.

        On the latest production release for Intel Macs, I can no longer connect to two external displays at the same time. I have to plug them in one at a time (sometimes multiple times before they register), and reconnect them after sleep. A very annoying regression.

        The hidden "Detect Displays" button in Display settings does nothing.

    • __natty__ 1 hour ago
      Yup I have the same problem with audio. And I found more problems last two years than in previous 10. I wonder if that due to some internal cuts in quality assurance or moving to AI and vibe coding more code than devs can review. But it may be subjective feeling.

      This is not the first time OpenGL got broken and fixed later. This is why software testing exists.

      I have my own share of criticisms for Apple, but if we treat every hiccup with doomerism, we will only miss the forest for a single, small bush.

      • saghm 34 minutes ago
        Did they actually catch it in their own tests? Or is this an external developer catching it for them? I guess if it works, it works, but this certainly seems like something they could be testing for up front.
        • bayindirh 24 minutes ago
          I remember seeing it as an entry in Known Issues list of one or two beta releases. The final releases didn't have the problem.
    • sgt 58 minutes ago
      Meanwhile, most of us don't have any issues. I think overall the Apple ecosystem is really good in terms of software quality. However, there are of course issues like with any system and if Apple is not able to reproduce something, the harder it gets to get it fixed.

      And the whole premise of your comment doesn't make sense as it's based on a bug in a macOS version that hasn't even been released yet. Of course stuff will break when you're busy developing.

      • saghm 32 minutes ago
        > Meanwhile, most of us don't have any issues.

        Do you have data on that? Based on peopel I talk to, it seems like there are plenty of people on both sides, and it's not clear to me which one is the majority.

        • lynndotpy 18 minutes ago
          The only data most of us can refer to are Google Trends. The unprecedented peaks for "How to switch to Android", "iPhone revert update", "iPhone fix battery", "iPhone slow", "new iOS sucks", "iPhone bad now", "How to block iPhone updates" all reached new peaks with the release of Liquid Glass in late 2025.

          Similar story for Macs. It's hard not to see the graph for "macos broken" ( https://trends.google.com/trends/explore?date=all&q=macos%20... ) or "macos slow" ( https://trends.google.com/trends/explore?date=all&q=macos%20... ) or "how to fix macos" ( https://trends.google.com/trends/explore?date=all&q=how%20to... ) and find any reason for this other than people having a surge in bad experiences with Liquid Glass.

          Of course, this is only Google Trends, and even if we interpret this as a 4x to 100x increase in bad experiences with Apple products with the forced introduction of Liquid Glass, it still might be the case that >50% of people aren't consciously experiencing problems from it.

        Regularly bugs reported during a beta do not get fixed until the next major release. If they do not, they will be closes as wontfix because they were fine to exist a whole major version.

        My macbook has been kernel panicking during every sleep.

        • sgt 46 minutes ago
          Been using macOS since the OS X days of Panther (2003). Since then, people were kicking and screaming about bugs that Apple presumably didn't fix yet, and that's probably true. But it does get fixed, and if you're just sensible - like not upgrading immediately, you'll hardly notice issues. On average, I'm about 6-12 months behind on major versions. I'm in 26.6.2 (Tahoe) right now
          • mort96 42 minutes ago
            I "upgraded" from Tahoe pretty quickly because Tahoe, even a year on, was such a buggy mess that I hoped Golden Gate would be better, especially after it was glazed as a bug fix release. But it just introduced new bugs without fixing the old ones. Staying 6-12 moths behind doesn't leave you with a functional system anymore, it's just differently broken.

      you really have to wonder how they managed to mess up this bad, and why they're doing nothing about it.

      local search is both broken on my mac as well as iPhone. I search for an app, and its app store entry OR settings pop up, not the app.

      how does this persist? do they not use their own products anymore? have they simply given up?

      This is a personal anecdote - I'm a games developer, working predominantly on Windows. Since last year I have to use a Mac to work with our iOS builds and I honestly don't understand people saying Mac is for developers - the number of actual outright bugs I run into every week makes windows look like something that came out of NASA. I eagerly awaited the release of MacOS 27 to maybe finally address some of them, and of course it just traded one set of problems for another. It's just shockingly bad - and unlike a true Linux system you have very little ability to fix some of those issues yourself too.

      My Mac has developed the issue of slowing down over time if not rebooted. Heavy GPU use accelerates the decay. It feels just like swapping to disk except it's not - swap usage always 0. I didn't have this issue before Tahoe.

        We may not be far off from finding LLM prompts embedded directly in software. Instead of savefile(data_thing), we might start seeing

          agentcall( claude, data_thing, "please save this file to the user's home directory" )
        
        
        and the author of that code will pat him/herself on the back then form a habit of telling his/her friends "I am an engineer, I have built over 100 software programs spanning multiple continents".

        I already see this behavior out of the tech support class that likes to participate in bureaucratic processes among gen z. The standards and expectations for what is colloquially "engineer", outside of bonafide engineering circles, has really fallen over the last two decades.

        The attitude that replacing functions with calls to AI agents is like totally okay in software engineering will eventually seep in too.

      • CharlesW 1 hour ago
        This isn't happening for me, if by "over time" you mean "several weeks" of heavy GPU use without a reboot. Consider the possibility that the root cause is not macOS.
        • LoganDark 1 hour ago
          By "over time" I mean that if I run local LLMs or play graphics-intensive games (like No Man's Sky's native Mac port) I can start seeing up to half-second (or longer) delays in switching apps, starting videos and much more with less than 5 days of uptime. Heavy enough usage will reproduce it within a few hours.

          If I avoid doing those things, it can last much longer.

          I have the 128GB/8TB M4 Max and I'm not even coming close to using up all or even most of the unified memory. I suspect it may be related to some form of fragmentation, though I have no way to know how.

          • CharlesW 1 hour ago
            I believe you, just suggesting that the issue may not be quite as general. I have a 64GB Studio M1 Max, so the years of hardware/firmware differences between us may be relevant as well. Hope you find a solution!
            • LoganDark 1 hour ago
              It didn't happen to me before the update, so I suspect it must be something about the update or how it interacts with the software on my system. Still, it's one of those issues I have no hope of seeing solved, because at this rate nobody doing development at Apple is actually going to leave a Mac running for days on end...
      • plqbfbv 1 hour ago
        I once worked in L1 support, and because we had to take calls @07:00 sharp (we were the only number a company of 40k people could call) and Windows updates were still a multi-hour endeavor, I stuck to rebooting daily (or shutdown+startup) all devices I use heavily, including MacOS.

        Over the past 8 years that has basically solved every bug all my colleagues ran into with MacOS. At some point my boss wasn't getting calendar notifications anymore for a couple weeks, "did you try and reboot?" fixed it in 5m. He later mentioned he hadn't rebooted in 7 weeks.

        I don't understand why people treat Apple devices like unbreakable analog AM radios, they're very complex computers like any Windows or Linux machines, with a huge state machine beneath it that is easier to reset daily/weekly than to keep working properly for months.

        • LoganDark 1 hour ago
          My Intel Mac didn't need to be rebooted. I would leave it running for months with no issues. Apple devices genuinely used to be that stable.

          I get that you can't generally expect things to be that stable. But in my experience they used to be and now they're not!

          My M4 Max was probably that stable too until Tahoe, although I rarely left it running for more than a few weeks between updates.

  • ryandrake 1 hour ago
    Sad but not surprising. Apple marked their OpenGL subsystem as deprecated all the way back in 2018 with macOS 10.14 Mojave and iOS 12. By some miracle it has kept working all that time. While I hate it that Apple can just up and declare a widely used cross-platform API 'deprecated,' it's their system, not ours. So, we should not expect them to care or lift a finger if they accidentally break it.
    • voakbasda 1 hour ago
      When they break stuff, developers should lift their middle finger in response. That they don’t I think reflects some kind of Stockholm syndrome.

        It's more an indictment of everyone else, buy a different computer and you're guaranteed to be buying an objectively weaker computer for the vast majority of work scenarios. And you're paying a comparable price for it too.

        It's so bad Apple can just abort M6 Pro and Max and reuse the M5 generation for an extra year because why not, the most powerful alternatives are still playing catch-up with the base M4.

          The rumor is that Apple decided to put the engineering effort into the M7 series to make a bigger leap.

          Engineering resources are finite. Expecting a company to release every version of every chip at every generation is not optimal. Some times it's better to put the development effort into a bigger goal that takes longer.

          I wouldn't call that bad. They're being smart about development strategies instead of forcing everything into arbitrary release goals to satsify marketing and shareholders.

          That's what I want from companies who development my products. This is a good thing.

          • bigyabai 39 minutes ago
            Apple's work is cut out for them; M7 and M8 desperately need a better GPU. These SOCs put up fantastically efficient single-core performance, but have some of the worst GPU compute efficiency you can buy. It also needs a better interconnect than RDMA, since Thunderbolt is snail-speed when networking several iGPUs together.

            Apple Silicon is a mirror into the Mac's decision paralysis. Apple wants to unify the Mac power users and iPhone casuals onto one silicon backbone, but can't decide who gets the short end of the stick. Tim Cook especially couldn't figure out how to ship a Mac Pro while retaining "ecosystem" level control over academic and prosumer customers. Professionals and researchers had a stack they wanted to use, and Apple didn't support it.

            Ternus will probably try to pivot Apple Silicon towards professionals, but he'll need to make software concessions to enter the true ARM HPC market. Ironically, that may entail Apple's rapprochement with Khronos to get the industry onboard with a CUDA stack alternative. Even a basic "inference hardware" GPGPU standard would put Apple Silicon back on the map for professional applications it has otherwise sat-out.

      You need to get your head out of your bubble and realize that this bug does not move the needle on anything meaningful.

      I work at a superscalar and we have also had about 40% increase in breaking bugs in prod year-to-year due to a lot of slop code. However, the engagement and revenue generated is up from the features. Why bother make a timeline and spend time and resources on things that the average user does not care about? Does the average person care about the OpenGL compatibility? No, so why would you spend effort on this instead of for example user engagement? Answer that.

        Engineers and their companies are super users on whom the whole Apple ecosystem depends. If we can’t run our applications on Apple’s operating system, or they break things for our users, we will leave.

        Take that lesson back to your company as well. It is easier than ever to switch between clouds and AI providers. It’s easier than ever to replace any software in house. This isn’t an idle threat; I’ve already moved off of several software platforms this year for other providers, and I’m probably doing the same for millions of dollars worth of business every year in the future as well. And my company isn’t immune to it either - our biggest customers are always looking for options to bring software in house. The more we disrupt them with “small bugs”, the more likely they are to leave.

          That is just plain false and assigning over-importance to yourself.

                The things mentioned are not "regular wear and tear" nor price/durability trade offs.

                    Yes, production units can fail. Errors can be made in some factory. Or from some supplier.

                    Not the same as designing a crappy keyboard mechanism, people have called out as crap for years, insisting on it, and it failing people again and again - only to come with fanfare 5 years later to revert it as if you're innovating by doing so.

                    Or like making parts non replaceable on purpose and having them get worse performance in newer versions of the OS for no good reason. (The complimentary thing to tieing OS features to newer versions of the hardware for no reason, even when support for them in hardware form is absolutely not necessary).

      "Why have X when Y costs $N in tokens" is becoming a tired thought-terminating cliche.

      It shouldn't be user's responsibility to have to get their binaries to work at all costs.

      How about they spend $25 in tokens to fix what they broke?

      Why, yes, of course, have all the devs in the world spend $25 and tons of time each, because Apple doesn't care about devs nor users.
