It's time to do a clean install of Mac OS, but I want to restore BTT after so does or can BTT use iCloud for backups?
Best solution is to export your current presets using Presets => Export Selected
Alternatively copy these files:
~/Library/Application Support/BetterTouchTool
~/Library/Preferences/com.hegenberg.BetterTouchTool.plist
Thanks, Will do.
