For a 2017 MacBook Air, macOS 12.* (Monterey) is the end of the line.

Monterey has not been one of the "most recent three", or received the latest versions of Safari, for two years. It is still enough to run current versions of

The Firefox Web browser, and most other major third-party browsers
The LibreOffice office suite
The GNU Image Manipulation Program (GIMP)
The parts of the Affinity Studio suite that are free with registration
