I recently got hold of a Balckmagic eGPU for my 2018 Mac Mini... Works great with most of my aps, including Camera Raw and Photoshop, but I am having some trouble with Bridge...
The Blackmagic eGPU uses the AMD Radeon Pro 580, so nothing partiucularly esoteric or rare.
When I set up the app to "Prefer External GPU" in the prefs pane, as per the instructions from Apple as to how to use the eGPU, I get an error on laucnh of Bridge as follows:
"Bridge has encountered a problem with the display diver, and has disabled GPU rendering which uses the graphics hardware. Please restart Bridge for an optimal experience. Check the manufactirer's weboste for the latest software"...
The eGPU has all the available firmware updates applied.
My questions are:
1) Is Bridge supposed to be working with my eGPU..?
2) If "yes", then what might I be doing wrong to make sure I am getting the acceleration expected...?
As I mention, I have checked both Camera RAW and Photoshop and both do appear to be using the eGPOU as expected.
Any thoughts most welcome...
Most likely it just isn't supported in Bridge. Apple is now going away from eGPU as they don't work on the M1 Macs. There wasn't much uptake and app support is spotty.
