M1 Macs need Rosetta 2 to run older applications. This will be removed in some regions with an update to macOS Big Sur.
The M1 from Apple is a so-called ARM processor. This is the same architecture as the processors in smartphones. Thanks to this, Macs with such a processor have better performance than those with an Intel chip.
The disadvantage, however, is that programs cannot simply be run on it. They either have to be adapted for the new architecture or translated. While the developers have to make the adjustments themselves, Rosetta 2 is responsible for automatic translation. In the beta for an upcoming update for macOS Big Sur, however, indications have now been found that Apple is removing Rosetta from the operating system in some regions.
macOS Big Sur without Rosetta 2: Possible legal problems
Specifically, two strings were recovered from the depths of macOS, which suggest that Rosetta will be removed from the operating system. In the affected countries, after the update to macOS 11.3, the texts “Rosetta will be removed after the update is installed” and “Rosetta is no longer available in your country. Apps using Rosetta will no longer work ”shown.
It must be said, however, that many apps have already been optimized for the new processor. This means that the technology is needed less and less. All other programs will no longer work in the affected areas after the update. It is not known which ones exactly.
But it is just as unclear why this has to be the case. It is believed that Apple is using the translationprozess violates copyright rights in some countries.
