Fusion isn't working for me on Tahoe on an M3 MacBook Air (worked fine before upgrading). I've tried repairing, reinstalling it multiple times, clearing everything related out of ~/Library. It loads slowly, seems to block other network traffic, then locks up (Application Not Responding), if I leave it long enough I get an error ("Sorry, Fusion was unable to save sufficient data for Offline mode and needs to go Online. Please make sure you have a working Internet connection to continue.") before it closes. Network Diagnostic Test is fine. Working for anyone else? Any ideas?

It’s not supported on macOS 26 Tahoe yet

This is why you should wait, if you use professional applications….. ;)
Especially if you have 3rd party (non-Apple) software, it can take a while for some developers to catch up.

I won’t be updating to macOS 26 anytime soon, maybe sometime next year.
I may try it out on an external drive.
I have some software that has only just got support for macOS 15 recently.
