# Does Apache OpenOffice work on macOS 28?

> **Short answer: this version will stop working.** Apache OpenOffice is Intel-only, so it won’t open on Apple silicon Macs from macOS 28. A newer version runs natively (—). If you’d rather keep the version you own, Keep86 is built for that, but we haven’t tested this app yet.

## Questions about Apache OpenOffice

### Does Apache OpenOffice work on Apple silicon?

Only through Rosetta 2. The version listed here is Intel-only; a newer version (—) runs natively on Apple silicon.

### Does Apache OpenOffice need Rosetta 2?

This version does: on an Apple silicon Mac it runs through Rosetta 2, which Apple supports in full until macOS 27. The newer native version doesn’t need it.

### How can I keep using Apache OpenOffice after macOS 28?

Update to the native version, keep this Mac on macOS 27, or keep the version you own in a macOS 27 virtual machine — Keep86 does that and shows its windows on your desktop.
