1. Close System Preferences

2. Copy this command into Terminal. You will be asked for your admin password

sudo spctl --master-disable

3. Unlock System Preferences > Security or check if the Anywhere button is selected.

4. Start UBNT Discovery Tool for Mac OS

5. If you want to maintain the security of the Gatekeeper as Apple dsigned it, copy this command into Terminal

sudo spctl --master-enable

Otherwise just select the option you want.

Ask Ubiquiti to please register the utility with Apple. It’s been four years…
