 A meta data file (.meta) exists but its asset 'Packages/com.unity.ide.visualstudio/Editor/Plugins/AppleEventIntegration.bundle/Contents/Info.plist' can't be found. When moving or deleting files outside of Unity, please ensure that the corresponding .meta file is moved or deleted along with it.
 
 Couldn't delete Packages/com.unity.ide.visualstudio/Editor/Plugins/AppleEventIntegration.bundle/Contents/Info.plist.meta because it's in an immutable folder.
