Again, Apple provided emulation technology (called Rosetta) to ease the transition across processors. The next chip transition came a dozen years later, in 2006, when Apple shipped the first Macs to run on Intel processors instead of PowerPC.
AIM EMULATOR MAC MAC OS
(In fact, a decent amount of Mac OS itself was run in emulation.) The PowerPC processors were so powerful that emulation didn’t cause much of a slowdown. To ease the transition, Apple added an emulator to Mac OS that let old software run on the new PowerPC Macs. In 1994, Apple abandoned the Motorola 68000-series processors that it had been using in Macs for a decade in favor of PowerPC processors from the AIM alliance (Apple, IBM, and Motorola). I started writing about Apple about the time that the company made its first chip transition.
AIM EMULATOR MAC FULL
I’ve been impressed by Apple’s use of ARM chips in new Macs while being skeptical about the prospects of a full transition.īut if we accept the Bloomberg report-and it’s from reporter Mark Gurman’s sources, which are generally excellent-it’s time to shift from speculating about whether or not Apple would do this and start to analyze why the company would make this move, and what form the transition might take. This week’s report from Bloomberg that Apple is planning on moving the Mac to its own chips starting in 2020 is the culmination of years of growing speculation about the future of the Mac.
