After upgrading to Mojave, Mac Pro does not start on first attempt

After upgrading to Mojave, Mac Pro does not start on first attempt. Requires "hard" power down and restart before displaying startup screen?

Hello Brettlb,


Thanks for that info and choosing the Apple Support Communities. If I understand correctly, since updating to macOS Mojave, you're having an issue with starting up your Mac Pro as expected. First, try running First Aid on your hard drive with the built in Disk Utility tool, as this can correct simple issues like you're experiencing.


Disk Utility for Mac: Repair a disk using Disk Utility


Next, use safe mode to start up your Mac as it does the following things:

  • Verifies your startup disk and attempts to repair directory issues, if needed
  • Loads only required kernel extensions
  • Prevents startup items and login items from opening automatically
  • Disables user-installed fonts
  • Deletes font caches, kernel cache, and other system cache files


Log into your user account and test the issue while in safe mode and then restart normally and test the issue again.


Use safe mode to isolate issues with your Mac ​

Cheers!
