State of eGPU for Macs – Catalina 10.15 Update
Mojave 10.14 raised this multiple eGPU support to four units. Catalina 10.15 has no set limit in my testing. The bad news is the system and applications can only use up to four eGPUs concurrently.
In Catalina, can all the GPUs support a display? Or can displays only work when connected to the working four eGPUs?
Can one app use 4 eGPUs, and another app use a different set of 4 eGPUs, so that more than 4 eGPUs are used?
Great news guys ! Apple just released first beta for 10.15.1 !
According to Apple's release notes, macOS Catalina 10.15.1 introduces support for the AMD Navi RDNA eGPU architecture !!!
So now we have official support for the 5000 series ! Yay !!!
@eyalg Unfortunately Apple screwed up. They either forgot to include Navi drivers or jumped the gun on stating support in the release note.
Really !?!? sad to hear that, I was already planning on purchasing a 5700 xt...
you tested the new beta and no go?
At this point I will believe anything about apple... disappointing...
I already purchased one lol. But at least it somewhat guarantees there will be support for RDNA eventually.
It does not seem to fix it according to the Apple Community discussion:
"I have installed the Beta 10.15.1 Beta (19B68f), and I am still having the same issue, apple logo, black screen, sonnet 550 with AMD 580x goes full blast on, then calms down, and does nothing after that. I still have to shut off the EGPU for 5 seconds, and then turn it on, in order to work again."
Also a full reinstall does not seem to help:
"I did a full reinstall from scratch to an empty drive. This does not solve the problem, after installation the first thing I am greeted with was the dreaded white screen of death."
