Yes it works with Sierra & High Sierra fine. It feels a little slow on start up but otherwise works fine. Jan 01, 2018 It doesn't work for me when using both USB and Thunderbolt. After some digging, I think it all has to do with High Sierra and APFS. High Sierra is deemed one of the worst OSX updates in Apple's history and it could be simply just a lack of support for spinning HDD. Sep 26, 2017 Further, due to this lack of notice, i have already installed High Sierra. The concern is that WD continues to be silent on this issue. No guidance, no announcement, not even an acknowledgment that their product does not work with 10.13.

I have a 1 TB WD external HD that won't mount. I connect it via firewire to my MacBook Pro running OS 10.13 High Sierra. My mac sees the drive, it just won't mount. I've also tried to mount it via USB, but again, my system sees the drive, but won't mount it. Does anyone have any suggestion what I can do?
