Since the application is not signed (I don’t want to pay the $99/yr) you will have to do a manual step in the console to allow it to run.

 

 

1. Download ClutchEdit_macos.zip, the app will be automatically extracted during download
2. Use the following command to allow it to run
3. xattr -d com.apple.quarantine ~/Downloads/ClutchEdit.app
4. You can now run it. You can move it to the Applications folder if you do desire
