Rosetta is perfectly safe for your Mac and is made by Apple so you should have no security concerns. Once installed, Rosetta automatically works in the background of macOS to make Intel only apps work on M1 and M2 chip Macs.įor most apps, Rosetta works so seamlessly that you won’t notice much difference in the performance of an app using Rosetta compared to one that’s been built to work natively with M1/M2 Macs. In 2020, Rosetta 2 was released as Macs transitioned yet again from Intel chips to the new Apple Silicon M1 chips. Rosetta 1 was first invented by Apple back in 2006 when Macs transitioned from PPC chips to Intel chips to enable PPC compatible software to work on Intel chips.
