Apple may soon disable Rosetta 2 on M1 Macs, macOS 11.3 code reveled
Just like the previous Rosetta technology, Rosetta 2 lets users run macOS apps from one platform on another. This time Rosetta 2 can convert Intel apps to the ARM architecture of the M1 chip. Although Apple no longer supports Rosetta, it is likely that future versions of macOS will make the program unavailable to users in some regions. iOS developer Steve Moser announced on Twitter that he found what appears to be a minor bug in the macOS Big Sur 11.3 beta. Apple has updated the Rosetta API with new functionality to exclude Rosetta from some regions.
“Rosetta can be disabled by upgrading to this version,” the software reads. The web page also clarified that Rosetta 2 will be excluded from Macs in certain particular regions.
Rosetta is only used in other territories. All applications involving Rosetta will be rejected.
At least for now, it seems that Apple has not disabled Rosetta 2, and the company has not made any public indication to do so in the future. The text may have been applied as a precaution in the event that new regulations were introduced later on. Although this restriction is not sure.
When Microsoft started work on Windows 10 for ARM in 2017, the company revealed that it would include a similar set of x86 emulation. However, Intel challenged Microsoft by saying that the x86 architecture has unique features, and that emulating x86 on another architecture needs permission from Intel. While Windows 10 ARM was capable of emulating 32-bit apps from the x86 architecture, 64-bit software emulation was only recently introduced in an Insider Preview build — which may be linked to Intel’s patents. Apple may be looking to face a similar conflict with its similar Rosetta technology.
Moser also pointed out that, on a related note, Apple has made updates to the game controls in macOS Big Sur 11.3 beta 3, which includes a new option to enable users to interact with friends in Game Center. macOS Big Sur 11.3 made a few non-significant improvements as well, such as a new warranty option under the About This Mac section and some changes to the Touch Alternatives menu.
