## Questions about KDiff3

### Does KDiff3 work on Apple silicon?

Yes. KDiff3 has a native Apple silicon version, so it runs on M-series Macs without any translation layer.

### Does KDiff3 need Rosetta 2?

No. The current version runs natively on Apple silicon, so it doesn’t use Rosetta 2 and isn’t affected when Apple removes it in macOS 28. Only an old Intel download of it would be.

### How can I keep using KDiff3 after macOS 28?

Keep it up to date from the developer. If Finder shows your copy as “Application (Intel)”, replace it with the current download.
