Why is Mac Mechanic so dangerous?

Mac Mechanic is a misleading system optimizer developed to trick Mac users into buying its licensed version. Once installed, it performs an unauthorized system scan and shows numerous warnings reporting hundreds of issues detected on your Mac.

The impostor promises to fix all the supposed errors and enhance system performance. But it's just trying to scam you by using fabricated scan results. There is likely nothing wrong with your device.

Mac Mechanic as a potentially unwanted program and scareware

Cybersecurity experts categorize Mac Mechanic as a potentially unwanted program (PUP) and scareware. The users can download the application directly from its official website. However, it typically comes bundled with freeware and appears on computers out of nowhere.

  • Intrusive ads popping-up while you’re browsing the web
