Turn on access in TextExpander for Mac

For privacy reasons, OS X does not allow third-party applications (such as TextExpander) to log keystrokes unless access for assistive devices is turned on.

In macOS 11.0 (Big Sur):

  1. Go to System Preferences -> Security & Privacy -> Privacy -> Accessibility -> TextExpander.
  2. Close System Preferences.
  3. Launch TextExpander.
