Anyone here boot there new iMac via an ext USB 3 drive?
I was but for some reason when I restart I randomly get the circle/slash. Usually if I then force shutdown, unplug the drive and power it down, then reconnect it will boot up fine again.
A few times that won't work and I'll get a gray screen or the Apple screen with the loading circle moving but clearly stalled on that screen. At that point if I unplug all USB (2&3) devices it will continuing booting to the internal drive.
I can't figure this one out because it's so random. I never get the same outcome twice in a row. Seems like it might be a hardware issue with the iMac rather than my ext drives.
Any one ever had this experience or want to guess what's going on?
