Accelerator version: unity-accelerator-app-v1.0.909+g1e7dfa1 MacOS version: Catalina 10.15.7 I got an error when I tried to install the accelerator. After spending a lot of time I found out that the problem is in the path to the service: /Users/<home>/Library/LaunchAgents/com.unity3d.accelerator.plist. The folder named LaunchAgents in /Users/<home>/Library/ didn't exist. In my OS I found folders with this name in paths /Library/ and /Library/Apple/System/Library/. When I created this folder in /Users/<home>/Library/ , I can successfully install accelerator.
