Does the app work? Have you tried to reinstall it?
The app works normally, reinstalled it many times, And even If updated to a new version still greyed out, I tried to refresh the icon with this Method I know it with searching:
- Go to the Application
- Show Packages Contents
- Then 'Resources' Folder
- There you will find the app icon
file with format .icn just copy it and press
Command + i to show file info
then in the top left there is a small icon preview click it and paste the file like command + v , This can change the icon with any icon you want, So if you change to the same icon this is like a refresh i think, in a nutshell i tried this but doesn't work.
