Open app from an “unidentified developer” via OSX terminal

Saturday 13 July 2019Saturday 13 July 2019

1. Open terminal
2. Type sudo spctl --master-disable and press enter/return
3. The usual “unidentified developer” system dialog will appear – click OK
4. Now do the usual open -a /path/to/application.app

To re-enable this, alter step two thusly: sudo spctl --master-enable

Context for this: I wanted to install Spaces Renamer so that I can name my OSX workspaces. As of OS10.15, you still can’t rename them.

I also had to disable SIP, as I explained in How to turn off SIP (System Integrity Protection) in OSX.
