Another important step is the expected loss of support for third-party kernel extensions in macOS 10.16. Lack of Intel x86 microprocessors compatibility in Mac is a deal breaker for us. We know that there’s a new (now not so new anymore) coreOS group that (I assume) manages the system’s core components, but might also work on marrying certain core aspects of macOS and iOS. But much more important than that is our workflow. With the announcement of macOS Big Sur (now known has macOS 11) and ARM Macs, some within the Mac tech circles think macOS is essentially becoming iPadOS Pro (for lack of a better term). Apple Silicon Macs include within Big Sur Rosetta 2, which translates Intel code into ARM code. Thank you. I am not really sure, but I think Metal is already supported on QT. I stress that this is uninformed, because all we have seen so far is a very limited view of the front end. If Apple does announce ARM-powered Macs at WWDC – and that’s still a very big if – it’s another milestone on a road which started in 1990 when Apple co-founded what was then Advanced RISC Machines Ltd, now ARM, thanks largely to the vision of the late Larry Tesler and the need for a processor for Apple’s Newton. New architecture means new software, which has been Microsoft’s Achilles’ heel in … Saying ‘Apple did it before!’ is irrelevant. * AMD can make GPUs compatible with ARM since they also manufacture ARM microprocessors (ARM Opteron) A move to a single architecture is great for margins; however, it is unclear to me that the consumer experience will be as good if software/hardware manufacturers cut ties with macOS. Yes, but the problem in science research and meetings (and other areas at our University like digitally signing research calls, teaching-lecturing, etc) is that 90% or so of researchers worldwide use Windows. But ARM Macs would be left out of the predominant GPU compatibility market, again booting software off the Mac platform, unlikely to return. There will likely be some kind of x86 interpreter to smooth the transition just like MS has done with ARM Windows 10. Here's a look at what the new standard will (probably) mean for Apple and Mac moving forward. 4. The section about virtualisation/emulation, in my opinion is the one that is the most speculative but no one will know until next week. In late 2020, Apple began switching its Mac hardware from Intel x86 CPUs to Apple's ARM-based M1 CPUs. Developers need to build versions of their apps which run natively on both Intel and ARM models, so-called ‘fat’ apps or ‘universal binaries’, just as has been done in the past. The garden will not be walled, but for those inside the garden there’s nothing of use outside and those on the outside just don’t bother with the garden anymore. Mobile GPUs are a big on iOS so Apple control them. Current Macs are based on Intel's x86 chip architecture. General CommentI know people have placed the actual meaning of the song, but to me 'Angel' will always relate to self injury.I'm fairly certain that's not why she wrote it, but that's what it will always mean to me. Apple is but one of Intel’s volume customers, and doesn’t dictate its product development. Xcode can cross-compile those to efficient ARM processor code, as it already does when building apps for iOS and iPadOS. Thanks to Ivan for pointing out my error, which I have now corrected, over when the MacBook was discontinued. Or offer both? A big glaring issue is Performance, meaning will an ARM based desktop or laptop computer have the CPU and GPU performance necessary for current Mac users to be happy?

Congratulations for a very good article. “Other than Catalyst apps, what type of Mac software would run on such a device?”. It is by far the most popular computing platform in the world. If you instead supply the AppleScript so that it can be built into an app on an Apple Silicon Mac, then that will run native without any need for Rosetta at all. Attempting to compare Rosetta with virtualization is unrealistic. However, today things are very different. It would not kill off the actual, Intel bound, Macintosh and the vast hardware and software it supports. Unlike Windows RT, the version of Windows 8 that powered the original Surface and Surface 2, this is a full version of Windows 10 with an emulation layer that allows it to run traditional desktop apps from outside the Windows Store. It will virtualize ARM on x86 and vice versa. Consider my previous point above. The only real wildcard here is Windows. Such a device would provide full iOS app compatibility, obviously. Small correction, or so I think: the MacBook was discontinued only last year, with the most recent revision being from three years ago, not four. There hasn’t been a dedicated macOS developer group at Apple for many years, which is probably the reason why macOS has been degrading here and there. This approach was used by Apple on the first PowerPC systems (Motorola 680XX on PowerPC), and it is what Windows on ARM does. What would that be? Many believe Apple will simply release a new compiler that will take existing i86 apps and compile them to ARM. But I think people should be paying attention to Apple’s more recent iOS switch from 32-bit ARMv7 to 64-bit ARMv8. And Catalina’s removal of 32-bit support has already wiped out support for most software where that isn’t the case. Part of the problem with PowerPC was the unsustainable roadmap, especially after all video consoles left and Apple was left alone supporting the new developments. Freeing its designs from Intel chipsets is probably even more important to Apple’s future than just changing CPU. Trying to do this any more quickly puts their success in jeopardy, particularly during this pandemic. Vulkan will be supported on macOS as well, since Vulkan over Metal is in progress. I read this very long set of comments and am surprised no one has brought up QEMU as an option for virtualization. It will do just about any CPU architecture on just about any CPU architecture you want to run it on. This reveals which SDK that app has been built with: if it’s Apple’s internal one, or that for Catalina or Mojave, then the developer shouldn’t have too many problems porting it to use the 10.16 SDK and create a fat build. However, ARM processors provide support for virtualisation, currently available in two Open Source hypervisors, KVM and Xen. • As such, the only way to run Intel CISC based CPU operating systems would be via emulation. Change ), You are commenting using your Facebook account. It seems that may be the same issues will be present with any kind of Intel vector instructions (SSE) going to ARM but it seems that this kind of code is not as popular on x86. A big concern to me is roadmap. Rewriting RISC programs for CISC is relatively easy. ( Log Out /  Some _offer_ to support macOS if the community collects enough money to buy a Mac for them (which – given that they personally don’t have a use for a Mac otherwise – is fair), as many GUI-based applications are very much focused on Windows, where you still have OpenGL, Vulcan, no Notarization, no privacy checks, no filesystem limitations, no arcane app bundling, etc. Where macOS does have to go low, that code is generally now written in C, thus already supported on ARM. https://www.amd.com/en/amd-opteron-a1100. Although IBM acquired that company in 2009 (by which time Rosetta was mature), by then most of its engineers were apparently working for Apple. PCMag.com is a leading authority on technology, delivering Labs-based, independent reviews of the latest products and services. So here are some facts. ARM-powered Macs are unlikely, for the foreseeable future, to run iPadOS, and frankly I don’t think anyone would want them to. So I’m definitely looking forward to ARM Macs. But ARM doesn’t need to replace Intels in Macs to beat Intel. Or there might be a special reference Macbook in the offering. …”“Macification of iPadOS” on the iPad Pro”? What is Thunderbolt 4. Apple would be turning its back on compatibility with all the predominant operating systems, those that run on Intel. A switch to ARM would accelerate this, a “culling” of cross platform apps from the macOS ecosystem so that mostly Apple approved (by use of official frameworks) software remains that doesn’t work/has no use on other OSes. Microsoft already did this with the Surface Pro X. Here they have a head start, as thanks to its iOS and iPadOS support, Xcode already fits the bill. The common ARM-based architecture across Apple’s products should … Following a patient’s nutritional status is key for establishing eligibility for hospice care. I’d really like to make sure theer’s some sort of x86 emulator for the ARM machines, but Linux also runs on ARM as well. Another big one would be OBS, which especially due to Corona restrictions has been used by more and more people suddenly thrust into the world of live streaming. LLVM has a lot to do in that effort. On iPadOS, they run on ARM. Tim Cook has stated that the transition of the Mac platform to ARM will take two years, which I take to mean that each island in the Mac ocean will have an ARM … They can’t expect the entire software market to have ARM Versions ready to go. But removing support for them in the first release of macOS 10.16 for ARM is clearly important to Apple. The first models were the MacBook Air and MacBook Pro. Personally I use VirtualBox, which is great for everything I want to do. How does the “developer testing unit” work? No, and I have explained this elsewhere. In fact, Intel translated all instructions into RISC like instructions to execute them. Will Apple be able to license this version for BootCamp? CPU usage can double if an application runs on a Retina screen vs. a non-retina one – just one symptom of many due to how hard it is to compete with Apple’s own functionality. Apple has and will continue to have great leadership as the customer experience is always #1. Maybe we’ll get a chance to try it soon. It’s foolish and fraught with failure. Sweet. There’s no doubt that Apple today has the money and engineering potential to develop their own system if they wish – it’s all a question of whether it has decided to make that investment, or possibly offer different solutions.
