I was using the current macOS release version and decided to try the current beta since I have an M1 MBP and more than anything wanted to run it as a Universal app. In preferences, I added Beta Builds and after I clicked on Download and Install - it didn't appear to be doing anything but spinning. Waited for several minutes and finally tried to Force Quit the 1Password Installer and it wouldn't let me. Tried three more times - nothing. Then tried a Restart but that hung up with the 1Password installer just continuing to spin. Finally had to shut down with the power button. After restarting, 7.7 Beta 4 was installed and apparently working fine. I've tried a lot of 1Password betas during the past 15 years and this is the first time I've had such a problem.
