Apple may disable Rosetta 2 on M1 Macs in some regions, suggests macOS 11.3 code



Just like the original Rosetta technology, Rosetta lets 2 users run macOS apps from one platform to another – this time Intel apps translate the ARM architecture to the M1 chip. Although I do not expect Rosetta to disappear anytime soon, Apple may disable it in some regions, as macOS 11.3 beta codes suggest just that.

iOS developer and MacRumors contributor Steve Moser shared on Twitter exactly what he found in the third beta version of macOS Big Sur 11.3, which was released today for developers. Apple has included new code in the Rosetta API that mentions the removal of this feature in some regions.

“Rosetta will be removed when this update is installed,”

; the code states. Another string makes it clear that Rosetta 2 will be removed from M1 Macs in some specific regions.

Rosetta is no longer available in your region. Programs that require Rosetta will no longer run.

At least for now, it does not appear that Apple has disabled Rosetta 2 in some regions, and there is still no evidence of when or if the company will actually do so. The notice may have been added only as a precaution in case the company faces any related restrictions in the future. But what would this limitation be?

Back in 2017, when Microsoft started working on Windows 10 for ARM, the company announced x86 appemulation just like Apple. However, Intel threatened Microsoft to claim that the x86 architecture has proprietary technologies and could not be imitated on other processors without permission.

Although Windows 10 ARM was able to mimic 32-bit apps from the x86 architecture, 64-bit app emulation was only recently added to an Insider Preview build – which may be related to Intel’s patents. Apple may prepare to face a similar dispute with Rosetta 2 technology.

On a related note, Moser also found changes that Apple has made to the game, controlling the changes in macOS Big Sur 11.3 beta 3, plus a new option to allow connections with friends in the Game Center.

macOS Big Sur 11.3 also brought some minor changes, including a new warranty feature under About This Mac section and a new Autoplay feature in Apple Music that previously debuted in iOS 14, and some adjustments to the Touch Alternatives menu.
