macOS Mojave 10.14.2 - MacBook Pro (15-inch, 2018) - Radeon™ R9 200 series GV-R928XOC-3GD - MANTIZ
I installed High Sierra and it works. Looks like a software problem. How can I help with the transfer of logs?
Hi, did you have any luck with this? I'm having the same issue with my MBP 13" 2018 with a Sonnet 650 enclosure. I'll be upgrading the card soon enough but figured I'd use the R9 while I'm waiting ... but no luck.
