【CONFIRMED】27' Apple Thunderbolt Display NOT working with Blackmagic egpu
My Backmagic eGPU just arrived this morning. The reason I brought it was my display — 27' Apple Thunderbolt Display and I thought this eGPU claimed to work with LG 5K UltraFine would be able to boost this display through daisy chain.
The prior setup was quite normal:
and... it doesn’t work at all.
The system could recognize the gpu and the display after install Maceditor's Purge-Wrangler, but nothing was on the screen. After reboot, it got worse, the computer got extremely slow and laggy. (This condition somehow reminded me of the old days when on High Sierra a Nvidia dGPU MacBook Pro doesn’t work with a AMD eGPU)
So this is the setup I’m using:
It works fine. And the Geekbench 4.0 OPENCL score was around 110,000. That’s normal.
How ridiculous it is that Apple just give up on all the devices and equipments before 2016 under TB3 so easily and recklessly. I am still wondering why 27 Thunderbolt Display doesn’t work as a 2nd-place device in the daisy chain and gotta be connected directly to the computer. @itsage @mac_editor
