# Does Flock work on macOS 28?

> **Short answer: no, not on its own.** According to Homebrew’s package data (checked October 5, 2026), Flock is Intel-only and its current download has no Apple silicon build. Apple says Intel-only apps stop running on Apple silicon Macs after macOS 27, apart from some older games. Keep86 is built to keep apps like this running, but we haven’t tested Flock yet.

## Key facts

- Architecture: Intel-only (according to Homebrew’s package data, checked October 5, 2026)

## Questions about Flock

### Does Flock work on Apple silicon?

Only through Rosetta 2. Flock is Intel-only: an Apple silicon Mac runs it by translating its Intel code with Rosetta 2, which Apple supports in full until macOS 27.

### Does Flock need Rosetta 2?

Yes, on every Apple silicon Mac. Apple has said that from macOS 28 Rosetta remains only for some older games, so Intel-only apps like Flock stop opening.

### How can I keep using Flock after macOS 28?

Stay on macOS 27 on this Mac, switch to an alternative, or run Flock in a macOS 27 virtual machine (UTM, VirtualBuddy, Parallels). Keep86 runs that virtual Mac hidden and shows the app’s windows on your desktop; see the test status above.
