Assuming that Apple’s ARM-based processors are competitive in performance, I don’t know why they don’t. I don’t believe that Apple will take this action unless they know they will. It has been going on for a long time.
Modern macOS is based on BSD Unix and can be easily ported to other CPU architectures. To be honest, Apple has the resources to port its software to any resources needed-x86-64, ARM, MIPS, Sunway, and back to POWER, Elbrus, RISC-V, and they can do it anyway. But they have made huge investments in ARM and can achieve greater vertical integration by doing so, ARM is like this.
Apple’s long-term strategy is already obvious. I still remember buying an iPad as a Christmas gift for someone in December 2012. Even then, Apple still claims to be able to replace laptops and provide “desktop-level performance”, which was a few generations ago. Existed. The functionality of modern Apple CPUs is several times that of CPUs purchased at the end of 2012.
Unless Apple’s strategy is always to run all its own devices on its processors, it is unreasonable for Apple to make such a large investment in its CPU development. Besides, it doesn’t make sense to create such powerful ARM devices (as opposed to products made by other ARM vendors) just to cram them into media consumer devices.
Apple has been planning to transfer these chips to its entire product line. They do this because they think they are close enough to Intel to work normally, or at least they can optimize their software enough to achieve parity or even surpass x86-64 performance.
Apple has done it several times before. When the Motorola 68K product line came to an end in 1993, Apple joined Moto and IBM and helped develop the PowerPC product line, which they used until the mid-2000s. When they couldn’t get a faster G5 processor, they chose Intel because it was the only way forward.
But I never felt that they liked to do this, or dismissed the products available. I remember that they kept their MacBooks on the Core 2 Duo far beyond their EOP because the first-generation Core i series did not satisfy them.
For 68K, PPC, and Intel, these three games are beyond Apple’s control. When Moto’s 68060 lacked some of the 040’s instructions that the classic Mac OS relied on, Apple was in trouble.
When Apple is unable to produce the PowerBook G5 unless its clock is too slow, it will continue to consume power and become hot, and the old G4 will beat it, and they will be stuck. They don’t want to get into trouble again.
Now, they will never be stuck unless they are stuck.
