I have installed Macos Catalina beta version. I know it is in beta version and it is not stable yet but it seems that the problems a bit annoying as it slowing down my day to day works. Below are my issues:1) icloud drive (in Finder/Sidecard) couldn't connect to the iCloud (not responding), thus I can't access to all my contents in iCloud2) some of the softwares crash or not responding eg. Quicktime, Preview even microsoft office (if heavy usage)3) And now, I couldn't update the latest verion of Catalina Beta (10.15). The instruction to update still appear in the notification eventhough I have downloaded, updated and installed. It seems that nothing happened.Any advise to overcome the above issues?Thank you
