However, Apple has revoked TNT’s position as a recognized developer, so the operating system no longer gives its signature a free pass. TNT’s code signature was trusted by Apple, so when macOS’ Gatekeeper saw software carrying the signature trying to install, it allowed it to continue. Why has CleanMyMac by TNT stopped working? It strips MacPaw’s code signature from the app, replaces it with its own, cracks it so it will run without a license, and then distributes it on free blog pages and torrents. Unfortunately, that popularity makes it a target for people and organizations who crack software and distribute it illegally. It’s very popular and has had excellent reviews from sites like Macworld and Cult of Mac.
