I am Unable to launch unity 5.6.x. in MacOS big sur. editor won’t show up.
attaching the log file.
unity 2020 works fine through.
this seems to be the issue

Failed to get socket connection from UnityShaderCompiler shader compiler! /Applications/Unity/Hub/Editor/5.6.3f1/Unity.app/Contents/Tools/UnityShaderCompiler”
