iMac shuts down without warning since installing my g-drive 8tb


#1

Since having installed my G drives and copied all my photos on it with my lightroom catalogue, my iMac shuts down without warning and I cannot restart it without unplugging in the wall and plugging back in. Then the scenario repeats it self and I can’t work on my pictures.I have had service it (iMac )in Apple store and they didn’t not find any problem with it… I am desperate to find a solution ! I have the thunderbolt three with an adapter thunderbolt two to my iMac maybe has something to do with it.

Instead of using Thunderbolt have you tried the USB connection? You have both options on the G-DRIVE.

Yes I have and I even turn it off (the g-drive ) and the silly stops the same … so,really not understanding the problème
