macOS Catalina - Tidbits & eGPU Updates
@itsage I misread that as “Navi drivers are in” 😭
The latest dev beta 11 (which is said to be the GM) does not solve my 2018 Mac Mini eGPU white screen of death issue.
The current ROM version is now 1037.0.78.0.0 (iBridge: 17.16.10571.5.1,0) - again, only the iBridge firmare was updated.
I have a similar issue (black screen instead of white screen) on the public release of Catalina, it appears that egpu somehow gets disconnected in the booting process. Switching the power supply off and back on brings the egpu back.
Here's the ROM version on my mac mini: 1037.0.78.0.0 (iBridge: 17.16.10572.0.0,0)
Did a little preliminary testing here. Biggest change for me is different scaled resolution options for my 5120 x 1440 display, Catalina now offers 3840 x 1080, 2560 x 720 and even bigger "retina scaled" resolutions. All of them but the native 5120 x 1440 are a bit too big for my tastes, but this is an improvement on what mojave offered.
When changing resolutions and/or closing lid on laptop the display occaisionally comes up in HDR mode, but as far as I can tell the apple tv app is neither playing back 4k/hdr capable movies in HDR or providing downscaled 4k content, which is a disappointment.
No apparent changes for me in bootcamp, still running build 295 but booting with egpu attached and igpu disabled, and hotplugging at windows logo to keep igpu active still work.
There is a 64-bit Steam client, but you have to jump through some hoops to get it installed on a Mac (why they don't just update it, I don't know....). This link will walk you through it. I did it and it works fine.
My egpu setup on bootcamp was great, 100% reliable when I had Mojave. I installed Catalina, now my eGPU rarely works on Windows. If I get back to Mojave and reinstall bootcamp, will it be fine again or have I installed the newest apple firmware that I can't go back? I have a 2018 MacBook pro with t2.
I don’t have any problems on Catalina + Windows 10 on both AMD + NVIDIA. Ensure your Windows version is 18362.295 or lower.
I mean, I had the most updated version of windows on Mojave, and the same one on Catalina. On Mojave I could boot it with the eGPU plugged in, on Catalina if I do that it gets stuck on the initial Apple Logo, so I don't think it's a Windows version fault.
Maybe resetting NVRAM and SMC helps
Gonna try that today! Thanks!
