My mac mini boots from an external SSD connected via USB 3.
Didn't have any issue until i upgrade to Sierra.
Most of the times i boot it load the white bar under Apple logo till 30% - 50% and after that it never boots in system i have to force shut down holding power button and boot again.
Some time i need to do it 2 / 3 times before i can actually boot.
I hear a disk spinning not sure if an external hard drive or internal hard drive.
What could it be? Any one with same issue?
