Resolution Note (2020.2.X):
The changes which caused these OSX regressions brought in other important performance benefits and cannot be removed. We are therefore unable to address this issue. In some cases (temporarily) disabling https://docs.unity3d.com/ScriptReference/Texture-allowThreadedTextureCreation.html may help, but note that this may also cause performance regressions, so it is not recommended to leave this permanently disabled.
