FYI, I updated and immediately the app wouldn't launch because my license key wasn't valid. I pasted it in several times, it always said 'nope'. Eventually I had to use the website to do an "offline activation" using the exact same key and that got it to work again.
So anyone who is upgrading, make sure you try to run it after upgrading - don't just assume that your backups are going to continue to function!
We currently support only stable publicly available builds of macOS, so there may be some issues with that. Once final version is available it'll be officially supported on our side.
that's a shame - I understand they must take a lot of support time. Office365 Business comes with 1TB of storage so it's pretty useful to have OneDrive upload from Cloudberry to be able to use that. I guess you still would say that's consumer-grade. Ta for the reply.
