Xcode can cross-compile those to efficient ARM processor code, as it already does when building apps for iOS and iPadOS.
#IOS ARM EMULATOR FOR MAC DRIVERS#
This is because – apart from in some of the deeper parts of firmware, drivers and macOS itself – very few developers now use processor-specific assembler code, but write in high-level compiled languages like Objective-C and Swift. For apps developed in Xcode which use supported calls in macOS, that should just be a matter of the developer opting to build a fat release of the app (in a new version of Xcode). 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. There’s little point in Apple launching new Macs which can only run ten or twenty percent of modern apps.

But removing support for them in the first release of macOS 10.16 for ARM is clearly important to Apple.įor ARM Macs to succeed, they need to run as much of today’s software as possible. Apple hasn’t yet provided mature replacement options either, and developers have been protesting that their apps still have to rely on kernel extensions. This has major impact on those using existing Intel Macs: kernel extensions are still the most popular way of implementing some low-level features, including support for many third-party peripherals.
Expect OpenGL and OpenCL to vanish shortly too.Īnother important step is the expected loss of support for third-party kernel extensions in macOS 10.16. macOS has just been prepared to make porting it to ARM processors more easily, with the removal of support for 32-bit software in Catalina. Here they have a head start, as thanks to its iOS and iPadOS support, Xcode already fits the bill. My favourite candidate is the MacBook, which was discontinued a year ago.īefore going any further, Apple and its engineers need a development environment which supports production of both Intel and ARM executable code.

The first Intel-powered Mac was an iMac, which made it simpler to design and engineer, but my suspicion is that any first ARM-based Mac will be a laptop model.
Freeing its designs from Intel chipsets is probably even more important to Apple’s future than just changing CPU.ĪRM processors not only consume less power, but as a result they also generate less heat, properties which make them ideal for use in laptops. For performance, efficiency and economy Apple will most probably be building these into a System on a Chip (SoC), and graphics SoC, just as in iPhones and iPads. But the processor is only part of the package: just as critical are the supporting chips in the chipset, including graphics and GPU, and those handling interfaces such as Thunderbolt. They originated as processors for desktop computers, with a lean instruction set (RISC) which enabled them to run relatively fast and deliver high performance at modest cost. Using ARM processors isn’t as radical a move as many claim, and they’re not only suitable for low-power system as is often thought. Trying to do this any more quickly puts their success in jeopardy, particularly during this pandemic. Then, probably in early 2021, Apple can release its first new models to the public. WWDC is an ideal time and place for this to occur, as it allows Apple to seed its developers with early systems so they can get testing, and porting their products to the new architecture.

Although few current Apple staff are likely to have been working for the company during either of those, there’s still corporate knowledge of how to make such changes. Macs have changed processor architectures twice now: from Motorola 68K to PowerPC in 1994, and from PowerPC to Intel x86 in 2005-06. If it does launch a new range of ARM-powered Macs, it will want them to be first and foremost a success, and very popular with both new and existing users.

Selling a Mac directly aimed at the iPad Pro market, or one which couldn’t run most Mac software, would be a very big mistake, and I’m sure that Apple realises that. Before going any further remind yourself that Apple is commercially very successful, and what it wants of any new product is for it to sell, without wiping out other major products. Some have taken the opportunity to make all sorts of wild claims, such as ARM Macs being little more than iPad Pros, only running software supplied from the App Store, and worse. This article looks at some of the issues which we might face if this turns out to be true – and I stress that, no matter how strong or ‘reliable’, until Apple announces anything these are no more than rumours. I’m therefore completely unsurprised at the strong rumours that Apple is preparing to announce them in ten days time at the start of WWDC 2020. I speculated about Apple developing Macs based on ARM processors over a year ago, and showed some controversial performance comparisons here.
