I just updated to version 3 but I still get this error. Anything I should try?

What is the version of your macOS? Is your iMac a M1 computer? Does restarting the Mac help?


I analyzed similar reports in this topic:

It's very likely an issue of Mac (or macOS) itself, I suggest you rest the SMC of your Mac:

  • For Mac with Apple Silicon, shut down your computer, wait 5 minutes, then power on the computer.
  • For other Mac computers, see the Apple Support article How to reset the SMC of your Mac.

Please let me know if you still face this issue after reset the SMC.
