Lightroom Classic Memory and Performance

This is crazy!

Lightroom Classic 13.5.1 is not supported on MacOS Sequoia, so unexpected things can happen I'm afraid. So as long as there is no update that is supported, close down Lightroom Classic if you are not using it. For me, this is the reason why I never upgrade MacOS until a few months after its initial release.

Thank you, that makes me feel better in a weird way.

Adobe has now clarified, Lightroom Classic is compatible. OP, you are likely seeing cloud sync problems. Look for other threads on this issue.

If you have sync to the Adobe Cloud enabled, you could try 'Pausing' it to see if it helps.
