Developers relying on Rosetta 2 to keep their legacy code running should begin preparing now, as macOS 27 will be the last to provide full support for the translation technology.
When Apple revealed Apple Silicon in 2020, it shared that the transition would be slow to ensure users and software weren’t lost along the way. With the announcement of macOS Tahoe during WWDC 2025, Apple has revealed that not only Intel Macs, but Rosetta 2 are on the chopping block.
