If you are on OS X El Capitan or newer macOS, you will need to temporarily disable the new OS "rootless" mode before installing required Mono Framework and X11 as follows:

  • Restart your Mac and hold down Command + R keys on the keyboard while booting to enable recovery mode. Keep holding these keys until you see the macOS Utilities window similar to the sreenshot above.
  • Once booted in recovery mode, navigate to Utilities > Terminal in the top menu as per the screenshot.
  • Enter csrutil disable in the terminal window and hit the return key on your keyboard.
  • Restart your Mac again via the Apple menu -> Restart.
  • Install Mono Framework and X11 as described in readme.txt (supplied with the Mac download) and reboot.
  • Re-enable "rootless" mode by going through steps 1 to 4 and entering csrutil enable in the terminal window in step 3.
  • Double check that SpotEditor app was copied outside of the extracted zip folder and if not, copy it to your desktop for a example. If it doesn't start on the first attempt from your desktop, please check System Preferences->Security & Privacy->General tab to see if it's locked there and unlock if so.
