    The official statement from Apple (emailed to developers 10 days ago) is that macOS 27 is the “final release to support Rosetta”, so the title is a bit off.

    They also say:

    > Please note that Rosetta functionality for older, unmaintained gaming titles that rely on Intel-based frameworks will continue to be supported.

    I interpret that to mean just enough of Rosetta and Intel frameworks will continue to be around, at least for macOS 28. Not specified which ones, or whether it stays any longer than that.

    I’m pretty curious of what that will look like exactly, because there’s a fair amount of system frameworks/libraries needed to get to a bare minimum “hello world” AppKit app. Add on top any number of other frameworks that might be used by “older, unmaintained” games that Apple sees fit to keep supporting. Does this ensure OpenGL is kept on life support? Will they consider Wine important enough to support, perhaps even after they drop native Intel games?

      Apple seems to slightly care about supporting Codeweavers/CrossOver from things I've seen, which indirectly makes Wine, Rosetta 2, and GPTK "important enough to support" since they're important features

        I wonder if Apple cares about docker/podman which uses rosetta on amd64 images

      • bombcar 44 minutes ago

        I read that as "Rosetta2 for 32 bit" will still be around, somehow.

    Wait, so.. how are we supposed to test Intel builds of our macOS apps from now on?

    I get it that macOS has to evolve, but that doesn't mean all apps have to drop Intel support at the same time.

    On hardware-level apps like my Lunar app I have plenty #if arch(arm64) because some features like reading the brightness nits or reading ambient light is different or completely missing based on the architecture. I need to test the UI differences based on what features are available.

    I don't see it viable to stay on macOS 26 for this, especially if we're going to see breaking changes again with the display and window server subsystem like we did with Tahoe. M5 support for Gamma table changes is still broken after so many months [0]

      You don't. You could stay on an old MacOS. Apple would prefer that you tell your customers to stop being poor and buy a new computer. They will make your situation increasingly unbearable until you do.

      The overwhelming majority of people haven't needed a new computer since 2016. The current economic situation makes a new computer a worse value proposition than it's been in 35 years. Vendors are responding to this situation by manufacturing obsolescence. Microsoft pulled the same stunt with Windows 11's TPM 2.0 requirement.

      • troad 37 minutes ago

        I think it's a stretch to call Apple's ARM transition "planned obsolescence". The M-series chips are very clear improvements on what came before and there is a clear rationale for that transition.

        We're talking here about an OS that hasn't even come out yet, that will get years of security support, for computers that Apple hasn't been selling for several years now. Seems pretty reasonable.

          I have a MacBook from 2017 and and m3 air today.

          For day to day tasks there is no difference.

          • troad 29 minutes ago

            I have a MacBook Pro from 2016 and an M4 Pro from last year. There is a night and day difference.

            I think "M series chips are no better than ten year old Intel chips" is a take that would be somewhat difficult to sustain, given the data.

          • ryukoposting 11 minutes ago

            Eerily similar story here. My wife was using her 2017 MBP (the one they got sued over) and she adored it until Tahoe suddenly caused Chrome to run like hot garbage. I bought her an open-box M3 Air. She likes the color. It doesn't provide any more value to her life than her 2017 MBP did, and yet we're out $1000 because Apple said so.

      • apetrovic 36 minutes ago

        That's overly dramatic. I don't think a new Macbook Air today is a worse value proposition than some Mac from 35 years ago. I just checked Apple prices from 1991:

            - Mac Classic II, the slowest of the bunch, $1.900, or about $4.661 today
            - Quadra 900, the fastest model in 1991, was $7.200 ($17.663 today)
            - PowerBook 170 was $4600 ($11.285)
        • ryukoposting 16 minutes ago

          "Value" and "price" aren't the same thing. A new computer in 1991 cost more, but it also covered a vastly increased set of use cases versus a machine from 5 years prior (assuming the hypothetical 1991 computer buyer had even owned a computer before). Today, you can buy a used MBP with an M1 and it will do everything a new MBP can do, and the differences compared to a new machine will be imperceptible to most users.

          Plenty of people would even be perfectly happy on an x86 Mac, too. Sure, there would be a perceptible difference compared to a new machine, but not enough to justify the price. That's what obsoleting Rosetta is about, it's about artifically making x86 Macs so unbearable that would-be happy users have no choice but to buy something else.

      • scioto 37 minutes ago

        I still prefer my pre-2016 Intel Mac since I can do more things that I want to do on it than my newer M4.

    • stetrain an hour ago

      Keep a macOS 26 machine around for testing. All Intel Macs will be stuck on 26 as well, so testing under 26 is probably best anyway.

    • mghackerlady 16 minutes ago

      IIRC Apple supported 10.5 extra long because of it being the last PowerPC MacOS. I wouldn't be surprised if they do something similar here. Keep an intel mac around, and you should be fine

      Isn't this a general form of 'how do we deal with the transition from a to b?'

      If your client's can get intel Mac's, then you should be able to get one. If they can't, why do you need to keep supporting intel Mac's?

    • al_borland an hour ago

      Keep an Intel Mac around or drop support.

      They followed the same path when moving from PPC to Intel.

      • bombcar an hour ago

        Arguably if you're shipping new fat binary code today, you should already have an Intel Mac around to test, because there might be subtle differences between Intel-on-Rosetta2 and Intel-on-Intel.

        It works until that machine dies and you need to scramble for a solution (again).

  • kalleboo 2 hours ago

    I hope they keep around the underpinnings for Rosetta 2 (without the macOS parts) just to keep supporting Intel virtualization for things like Docker. Heck then anyone who really needs to run some old Intel app can run a virtualized older version of macOS.

    But I wonder if they're eager to drop support for the Intel TSO memory model from their CPUs.

    • zitterbewegung an hour ago

      Apple will keep Rosetta 2 support for Intel virtualization. See https://developer.apple.com/documentation/apple-silicon/abou...

      • andor a few seconds ago

        The page doesn’t actually say that explicitly

    • stetrain an hour ago

      I read somewhere that the part that allows a virtual machine to use Rosetta inside the VM is sticking around.

      MacOS on ARM can't directly virtualize an Intel OS using Rosetta today using the native virtualization framework, you need something like qemu for that. But you can use an ARM linux VM with the Rosetta framework installed internally to run x86 containers, which is I think how docker desktop and similar alternatives are handling it.

    • lxgr an hour ago

      Same here. Would be very sad to lose Wine capabilities as well, and presumably these have minimal macOS dependencies.

      • jeroenhd an hour ago

        Wine can run on aarch64 with FEX reasonably well already, no special instructions or hardware acceleration required. There's a bit of extra overhead, but that shouldn't be a problem for old games on modern hardware, they should run about as well.

    I'm curious what options that leaves for docker. I assume the pattern of building/running linux/amd64 containers on MacOS is pretty widespread.

    Edit: "Apple says that it will continue to support older, unmaintained gaming titles with Rosetta along with software running Intel binaries in Linux VMs beyond macOS 27 . There could also be future security fixes." - https://www.macrumors.com/2026/02/16/macos-tahoe-26-4-rosett...

    No Apple citation shown for that, though seems plausible.

    • akreal 33 minutes ago

      AFAIK all ways of running docker on MacOS rely on a amd64 virtual machine with Linux kernel in it.

      • tyingq 6 minutes ago

        docker --platform linux/arm64 depends on amd64 ?

  • ieie3366 an hour ago

    I bet it must feel good for the macOS engineers to remove the intel support. Probably much easier to do development for the OS as well

    • mghackerlady 12 minutes ago

      If it's anything like the last time they dropped intel, I wouldn't be surprised if they make sure darwin still builds on x86. Going all arm all the time is good business, but it isn't like apple to not have some kind of fallback

    • 404mm an hour ago

      As a consumer, I’d like to see the end of “universal” builds for various apps. It made sense for a while but downloading and installing ~60% larger bins just doesn’t make sense 6 years later.

  • whatever1 an hour ago

    Whatever. We have public utility OS, all the hardware vendors should be forced to provide open-source working drivers after they stop supporting their hardware.

    If they are afraid of IP leak, well, they can continue support.

    My desktop I built in 2012 is still working running ubuntu, even after Intel & MS decided that it is EOL with the release of windows 11.

  • rootsudo an hour ago

    Wow and darn I guess last support update to fully depreciate intel MacBooks. Used prices already are cratered.

    They are great heavily supported Linux machines though. They work out of the box gorgeously with numerous distros and being usbc is nice. For $100-200 for a mint condition model, it isn’t so bad.

    • compounding_it an hour ago

      >They are great heavily supported Linux machines though.

      Since the release of Touch Bar based Macs (which contain apple silicon) this has not been the case. The Macs that are well supported by linux and work very well were abandoned long time ago.

  • nerdjon 2 hours ago

    This seems less about why it won't be supporting Intel and more about why Rosetta 2 will be going away, which seems mostly related to cleaning up code that is no longer necessary once Intel is not supported.

  • skywhopper an hour ago

    Bad headline. This tweet attempts to explain why Rosetta 2 will no longer work. Which is because the OS no longer supports the Intel platform. That does not explain why the OS does not support the Intel platform.

    • icedchai an hour ago

      Because it costs them money to maintain it, and they'll make more money when people upgrade to M series?

      In all seriousness, it's a little lame. Consider that the Intel Mac Pro (2019 model) was still selling in 2023! That's not that long ago, and those were their highest end machines in terms of memory capacity. The "new" Mac Pro has since been discontinued...

    • lxgr an hour ago

      But it does?

      > Rosetta 2 requires almost the entire OS to have Intel support.

      The implication here being that (almost) the entire OS having Intel support is not trivial.

    Maybe Microsoft will finally update the Minecraft launcher to support Apple Silicon. Last I looked they tried to close the bug report, someone reopened it, then there was a system migration and I lost track of it.

    It’s almost like they did the work to get the actual game running on Apple Silicon, but installed Rosetta in the process, then just forgot about the launcher.

    I always refused to install Rosetta on my Mac, so I could get a big warning if I was about to install something that wouldn’t work in the not too distant future.

    I am missing something ? If I read the link in xcancel.com correctly, it says what I would look at as "intel emulation" will be removed in the next release.

    So, it looks to me application vendors who depends upon this emulation was given proper notice of this removal. So I think you should complain to the vendors instead of Apple.

    Most times I tend to criticize Apple, but this time seems Apple just moving on to avoid "bloat" and "cruft" from being carried forward in future releases.

    OpenBSD does things like this all the time and they get praised for it, which I agree with. Apple did the same with this and some people are upset :)
