Two Thunderbolt 3 ports on iMac Pro suddenly stopped working. Other two work fine.
I'm numbering the ports from right to left, facing the back of the computer.
UAD audio interface plugged into 1st port. LaCie 2big dock plugged into 2nd port. 4K monitor plugged into 3rd port via HDMI to Thunderbolt 3 adapter. Suddenly the light goes off on the LaCie drive and the audio interface is no longer recognized. The monitor still works fine.
I unplugged everything and restarted the computer. The monitor wouldn't work in the first two ports either. The audio interface and LaCie drive work fine connected to 3rd and 4th port.
