Only booting in safe mode cant get AHT running
What still works is:
- Mac Pro starts to boot
- gives the chime
- Apple logo,
- spinning wheel
- blue/gray screen
- HDD seems to do some more but the screen stays blue/gray.
In save mode it does boot completely.
Please advice in which steps to take to find the cause of this problem.
