I have been using an old version of NA for ages, because I assumed it would auto-update when requited but it turns out there was an M1 compatible version 2 just waiting for me on the downloads page.
It took a little while to sort itself out & authorise everything but I think it's pretty much there now.
HOWEVER. In the prefs, it says the Application location is invalid. It certainly hasn't been invalid up to about half an hour ago. Everything still seems to work so it's just kind of annoying rather than a real problem.
I've tried restarting etc with no success.…anyone know how to fix it?
