Same here, trash can mac pro, and when I launch the mac player, it just sits at a black screen. 10.14.5 version of the OS
Same issue here: 1.0.0.792-d4adb056
Mojave 10.14.6
Mac Pro (desktop) (Late 2013)
3.5 GHz 6-Core Intel Xeon E5
32 GB 1866 MHz DDR3
AMD FirePro D500 3 GB
Same issue here, Mac Pro (6,1) w/ AMD FirePro D300 2 GB
Just downloaded and installed the app now, so definitely the lasted version.Plex.log (46.8 KB)
Same issue here:
MacBookPro5,3
NVIDIA GeForce 9400M
NVIDIA GeForce 9600M GT
Thanks!!
Same issue with me, black screen on launch. Hackintosh with a Radeon RX 580 8 GB. Plex Media Player has been working perfectly since initial release with Plex server (hosted on unRAID server). Plex.log (28.1 KB)
Same issue. Splash screen (PLEX), then black. Preferences don’t come up.
Mac Pro 2013 (trash can), nothing exotic. Plex.app.tv runs just fine, and has for a few years. Plex media is on an external drive. Twin monitors.
Same here with Plex.app 1.0.0 on 2013 Mac Pro running macOS 10.13.6. Guessing you now have enough reports about this issue on this machine. Will wait for a fix and continue using the web-based player for now.
Thanks.
Can you post how you got it working for the community?

I did absolutely nothing. I just kept attempting to open the app and after a day or two, it just started to open successfully without any problems. I assumed there had been a fix on Plex’s end as per the thanks in my post. In any case, the new app seems to work fine now.
having the same issue here too with an eGPU .

Same issue here on a brand new install on a Mac Pro (Late 2013) running macOS 10.14.6 - Plex logo appears and then screen goes black. I do have Plex Media Player installed.
Edit: When I run the app as root via Terminal, it spits out this CGL error:

yeah this is making my mac pro feel like an actual trash can.
Another Trash Can Mac Pro user here having the same exact issue.
Playing from app.plex.tv works perfectly.
Adding myself to the pile. Mac Pro (late 2013), 3.5GHz 6-core Xeon #5 with AMD FirePro D500 3 GB. Black screen after Plex splash. Other server access methods work fine.

Black Screen on app load, freshly downloaded version 1.0.0.792-d4adb056
ALSO, I downloaded the new version of this app because I was getting choppy audio with the older version, but I just checked the web player, and im getting choppy audio on it too, seems like a lot of Mac Pro 2013 users here, anyone else experiencing choppy audio?
Add me to the list of Mac Pro 2013 fails. Using latest pkg just black screen after Plex splash logo. Chrome and Safari access work fine.
Thanks for the extra information folks. This is one of the top issues for us to solve. Far from forgotten!
Still an issue with 1.1, tried today. Cheers!
