You can still remove annoying agreement prompts from Mac disk images (.dmg files)

I got tired of accepting agreement notices when opening distributed disk image (.dmg) files, so I created this script. It should work until certain people decide it shouldn’t. Create a MacOS Service using Automator with one Run AppleScript action, and make the service accept documents in Finder. Paste the following AppleScript into the Run AppleScript action and save. Here’s the shortest complete documentation I could find (written by Ben Waldie, an extremely proficient Mac automation enthusiast) that explains how to use Automator to quickly deploy AppleScripts as MacOS Services.

After you’ve added the MacOS Service, when you encounter a disk image that you’ve downloaded that wants you to agree to something before it opens, just click “disagree”, then launch the service from the contextual menu (right-click the disk image). After a few seconds (depending on the size of the image), you can double-click it and it will open with no further nagging.
