How do I allow the opening of all applications from a specific website? I frequently download from an unidentified developer, and I want to be able to always allow opening downloads from them. How can I do so?

However, I don't want to keep an option to allow apps downloaded from anywhere, although on a side note that option seems to have strangely disappeared.
This is the only option I'm aware of:


Navigate to 'System Preferences > Security &amp; Privacy > General'
Click the lock on the bottom left of the window and enter an admin password
Click the radio button that says 'Anywhere'
Click the lock in the bottom left of the window again to prevent further changes


You would have to remember to go back and change it though when you're done downloading applications from that specific website/developer. Yes, it's a pain, but you could set a reminder for yourself with a date on it so that your Mac can remind you to change it back at a certain time!
