Workflow to remove the quarantine lock from files for macOS.

Developers have a lot of programs that are not notorized, Java web apps like .war files, for example. These are files that I created and know are not malicious, but trying to open them in anything on macOS results in getting a dialog like:

So I decided to write a Quick Action in Automator to make it easy to disable the quarantine lock on any file.

Simply place Remove quarantine lock.workflow in the ~/Library/Services directory.

Right-click on the file in question, then select "Services", then choose "Remove quarantine lock" from the "Quick Actions" menu item. There is no output; the file will now be usable.

The workflow is three steps:

1. Workflow receives the selected file

2. Run AppleScript to get the absolute path of the selected file in standard Unix format. This was taken directly from my GetAbsolutePath workflow.

3. Run a one-line shell script that actually disables the quarantine lock. The command it runs is:

   xattr -d com.apple.quarantine $1

   where $1 is the filename with path from step 2.
