SwitchResX broke my color profile, how to restore?
Per campyguy‘s post in https://forums.macrumors.com/threads/switchresx-cannot-remove-fully.1893707/, here goes how to get rid of the annoying "SwitchResX" prefix.


Open Terminal and enter the following Command:
ioreg -lw0 | grep IODisplayPrefsKey
Return of last step should be ended like: ... AppleBacklightDisplay-610-a031, remember the "610" and "a031" hints.
Go to folder "System/Library/Displays/Contents/Resources/Overrides"
Find the file folder "DisplayVendorID-610" as per the hint.
Edit the file "DisplayProductID-a031" in text editor with super admin permission (such as "sudo vi" command), delete the "SwitchResX" word in the file.
Reboot. (Don't forget to delete SwitchResX profile files in your ColorSync folders /Library/ColorSync/Profiles/Displays/ and ~/Library/ColorSync/Profiles/


Hope this finds you well.
