If you're seeing a dialog box that states "witchdaemon is an application downloaded from the Internet. Are you sure you want to open it?" every time you try to use Witch, this is a sign that the macOS file quarantine wasn't removed from your download for some reason.

Follow these steps to fix that problem:

1. Open Witch's System Preferences panel and uncheck the Enable Witch box.
2. Quit System Preferences.
3. Open Terminal (in Applications > Utilities), paste the following bit of code, and press Return: xattr -d -r com.apple.quarantine ~/Library/PreferencePanes/Witch.prefPane/
   Note: You won't see any output (other than the Terminal's prompt) when you press Return.
   If you see a message about no such file, you probably have Witch installed for all users. Please reinstall for the current user only, then try these steps again.
4. Open Witch's System Preferences pane and re-enable Witch.

If the process worked, you shouldn't see the warning dialog when you enable Witch. If you've followed these steps and you're still seeing the warning, please let us know by opening a trouble ticket.
