macOS Dequarantine
Tired of dealing with the annoying processes necessary to run an unsigned application on macOS?
Here’s a simple thing to make your life a lot easier: dequarantine.zip
Download this file, open it up, double-click the dequarantine.workflow file, and then install it as a Quick Action. Now if you want to let an unsigned application run, right-click (or ctrl-click) it, select “Quick Actions,” then “dequarantine.” And then, done.

Have fun.
How it works: All it does is run xattr -d com.apple.quarantine on the selected file(s), which just tells macOS that you trust the source of the files. It makes no modifications to the files or your operating system, it’s just removing a metadata flag.
