"Squad SDK Unreal Editor" on UE 4.16.3 Windows 10 on MacPro newest Model 16GB
UE is initializing quickly towards 73% where it spends a few minutes on shader compiler work, after that it goes quickly up to 95% where it spends around 20 minutes on shader compiler. At some point it finishes this work and CPU use drops to a few % with the only task left running "Unreal Editor" without any shaders or other apparent processes.
It stays that way for hours until task is ended manually.
I have turned off everything in Windows i could find in settings that might interfere.
Any ideas ?
