Sometimes Mac's accessibility permissions becomes corrupted, and weird things start to happen.
For example, Steam applications will complain that accessibility permissions are required, even though they apparently are already granted.
To fix this, reset the accessibility permissions cache:
- Launch
Terminal.app
- Enter
tccutil reset Accessibility
- Quit Terminal
- Launch
System Preferences
- Select
Security & Privacy
- Select the
Privacy
tab - Unlock the console.
- Add the appropriate application (e.g.
/Applications/Steam.app
).
