Question: Mac Pro shows apple and black bar 3/4 complete then freezes

Ladies and Gents-

The screen is frozen on the startup bar about 90% across. Have never seen this before.

Reset PRAM did not help.

(Beautiful light grey screen , grey apple and proper bar going across, just stuck at 90% across)


Any thoughts?

Thank you in advance!

Boot into Recovery Mode and reinstall Mac OS:

This will be an install "in place" and shouldn't affect any of your own data or third party applications. But that said, you should always have a backup.
