State of eGPU for Macs – Catalina 10.15 Update
TL;DR Catalina breaks HDCP in videos (Apple TV App) on external displays
I took the risk and updated from Mojave to Catalina 10.15.3. Now, I noticed a very annoying bug. Whenever I try to play a movie or Apple+ (i.e. For All Mankind) the Apple TV app would either crash or the movie window would just disappear. I can still hear audio for a few seconds. I tried a few titles from my library and noticed that some movies, especially older, will play flawlessly, others will force the app to crash. I believe it has something to do with DRM and HDCP. It seems newer movies/streams use an updated digital rights protection. I can play Apples video just fine with the eGPU attached if the video window is on internal display.
Any ideas how to solve this bug?
Side note: with High Sierra, I also experienced occasional random video artifacts and sometimes even severe crashes (full freeze/reboots) when playing videos via iTunes. Problems went away by updating to Mojave. With Catalina the crashes are back.
EDIT: After further trial and error. I noticed that basically any movie with a 4K label won't play via eGPU external monitors. Older movies with a simple HD label will play.
Do you have similar problems and possible solutions?
Anybody on the Catalina 10.15.4 beta? How was the experience and can you guys see the boot screen/startup disk picker while the display output is from the eGPU?
I really hope those boot screen issue are fixed
@ikir, sadly nope, i can boot with the eGPU connected but i select a disk to boot, i have a blank screen and i have to wait for purple artifacts to appear and then i get screen output with login.
Argh. Are you filling bug reports guys?
So my 2015 MBP updated to 10.15.3 last night and now I've got an issue where the macbook does but doesn't recognize my RX580 gaming box - the computer boots and using Splashtop, I can see that when I log in to the desktop the system says that no removable GPU is detected, until I unplug my macbook from the dock and then it says "eGPU not disconnected properly". Purge-wrangler is also popping up every time I boot asking if I want to reapply the patches after an update, to which I always say yes and enter my password into terminal but then it tells me the fix has already been applied and I need to uninstall it first to update??? I can't seem to figure out how to do so. I'm hoping that'd fix things.
since 10.15.3, my 2018 macbook pro crashes every night when left connected to my razer core x/vega64. moreover, the login will hang after the crash unless i disconnect the egpu first. this is pretty frustrating, as i use the razer core x as my power connection for the laptop at home, and now i can't leave it charging overnight or it will crash. i've submitted every single crash report, but i have a feeling apple doesn't give egpu problems much priority 🙁
Seems like 10.15.4 has caused that dreaded "no removable GPU" issue to start cropping up. It was all fine and good today, update ran, and now screen flicks on and then nothing on my attached monitor. Just goes back to the laptop screen, and the icon disappears. Running a Macbook Pro 5600XT (Sapphire Pulse). Tested to see it working on my Windows laptop. Something changed in macOS to cause this.
