Apple fixes Rosetta removal issue

Apple has addressed an issue in macOS 27.2 where updating to the latest macOS version could remove an existing Rosetta installation. This tool is essential for running Intel-based applications on Apple Silicon Macs.

Rosetta no longer needs manual reinstallation

Previously, users had to manually reinstall Rosetta after an update, but the macOS 27.2 update automatically retains it. This change was highlighted in business-focused version notes by MacRumors.

Apple confirms Rosetta retention but offers no explanation

Apple’s official documentation confirms that Rosetta is now retained during macOS 27 updates. However, it does not explain why the removal occurred previously or whether it was intentional or a bug.

Rosetta’s removal caused practical inconvenience

For affected users, the removal of Rosetta required an internet connection and user intervention to reinstall it on demand when launching Intel applications. The new update avoids this unnecessary step.

Rosetta’s future is limited

Rosetta was introduced in 2020 with Apple’s first Silicon Macs to translate Intel-based applications for Apple chips. However, it is nearing its end, as macOS 27 Golden Gate is the last version to fully support it.

Future macOS will limit Rosetta compatibility

Starting with macOS 28, expected in 2027, Rosetta compatibility will be limited to certain older games that rely on Intel components. Apple has not changed its timeline for phasing out Rosetta.

Users can identify Intel-dependent software

To help users transition, macOS 27 already includes an inventory of applications that may no longer function after Rosetta’s removal. Users can also check Settings, General, then Information to find software still reliant on Intel architecture.
