I tried several approaches.
The Launcher works flawlessly and the game is updating without problems. When I press "Play" it boots up, on the first boot the Loading Screen appears and the short movies play, but afterwards it loads infinitly. Like I see the yellow SWTOR cursor and I also hear sounds but it remain on the loading screen with the blue circle spinning.
I am currently on an iMac Pro with MacOS Big Sur 11.1. I already got LOTRO working flawlessly.
I tried also different bottles like windows 7-64 bit windows 10 64-bit,
then i tried activating dxvk, esync etc. its always the same behaviour. Even with swtorfix. it keeps spinning forever. I also tried the step by step guide from the tips section its always the same. Has someone a suggestion?
