How Mac Master works

Mac Master by FonePaw is a Mac cleaner. According to, it’s an app for cleaning up your Mac “in various ways”. These sorts of apps should always be scrutinized. Some of them are built to always find some issues with your computer so that they appear more useful. It’s probably why Mac Master is configured to start on your login. This way, it doesn’t need you to run it – it can just scan your Mac by itself and then prompt you from time to time.

Like other cleaners, FonePaw’s Mac Master:

  • finds large and old files,
  • check for duplicate files,
  • looks up cookies and other browser data,
  • helps uninstall apps,
  • it can shred files.

In other words, all things you can already do yourself for free just by using the features present in macOS and in your browsers ( I’ll just say again that Mac Master is a paid app.

Removing unnecessary files once in a while is good, but most people don’t need to do that often. A few GigaBytes here and there won’t do anything for your Mac’s speed. And deleting temporary files, cache, and cookies might not be helpful. Some of these files, though unnecessary, hold useful data in quickly accessible files while barely taking up any space. And if you do need to delete those files, like for privacy reasons (What happens when you delete cookies), your browsers provide all the needed tools for free.

That’s why it’s good to be skeptical of cleaners. They can give you a list of unnecessary files, but you should be critical about which of the files you actually wish to remove. Mac Master

All the while, Mac Master takes up hardware resources with its regular scans, slowing down your Mac.

Mac Master is detected by three programs on VirusTotal.

Issues and problems

Mac Master is safe to use, but it is a potentially unwanted program. Some anti-malware apps warn their users about it (VirusTotal link). This is a sign that Mac Master doesn’t have a good reputation. Same as Qbit Mac Cleaner, Tweakbit Mac Repair, and many other optimizers for macOS devices.

The company that made Mac Master, FonePaw, also offers a lot of other apps, utility tools, and programs, including a tool for spying on other people’s phones. Not everyone is super happy with FonePaw (Trustpilot link). A frequent complaint is about not being able to get a refund. That’s because FonePaw has a bunch of restrictions for when it refunds purchases, even while Mac Master’s free version has limited functionality. Most people understandably assume that a refund can be obtained for any reason. But, according to FonePaw, if you buy the wrong program (they have a lot of different utility programs), if you don’t understand how to operate it, if it doesn’t work, or if you just don’t want or need it anymore – you’re not eligible for a refund. So, be aware of that if you ever buy anything from FonePaw.
