Hello! What processor and internal GPU does your macbook have? I am planning to do the same setup with macbook 2014 750m, akitio thuder 2 and Radeon Vega 8gb. I don’t understand yet whether the components will fit together.

Macbook mgxc2 (2014 with 750m), akitio thunder2, GTX 970 by NVidia, Corsair VS550 PSU, External monitor Benq 3201 4k

Did you also try this on the "official" Big Sur release?
I'm planning to build a similar setup for my 2015 MacBook Pro.


To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.
