Mac says the app is "damaged"? macOS blocks unofficial apps downloaded from the internet. The app is fine; this is just Apple's strict security filter.

To allow the app to run:

Open the Terminal app on your Mac.

Type xattr -cr  (make sure you leave a single space at the end).

Open Finder, locate the extracted folder, and drag and drop the app directly into the Terminal window.

Press Enter. You can now double-click the app to open it normally.
