If you've started to see messages on your Mac from an application called Mac Auto Fixer, warning you of possible infections and the need to clear them out with the premium version of the app, then you're probably wondering what it is and how it got there.

We explain what Mac Auto Fixer is, why you shouldn't have it on your system, and how to get rid of it.

Where did Mac Auto Fixer come from?

Mac Auto Fixer is regularly found in free third-party apps that bundle other software into their downloads. This 'piggy-backing' is essentially a deceitful way to trick you into installing an app that you didn't actually want.

These type of apps are called Potentially Unwanted Programs (PUPs for short) and are sometimes missed by antivirus software as they are not seen as dangerous, just irritating.

Is Mac Auto Fixer harmful?

Not really. It's not strictly a virus or malware as far as we can tell, instead it's more of a persistent ad that tries to convince you to upgrade to the full paid version. That being said, you should remove it from your system once discovered.

Should I upgrade to the paid version?

No. Mac Auto Fixer and its ilk are not thought to be reliable ways to keep your Mac safe. Instead you should look to free and paid options of apps such as Malwarebytes, CleanMyMac X or those you'll find in our Best Mac Antivirus chart, which will maintain your system without having to sneak on to it in the first place.

What is Mac Auto Fixer?

How can I get rid of Mac Auto Fixer?

The aforementioned apps would be the best way to go, as Mac Auto Fixer can bury itself in various places across your systems. CleanMyMacX, Malwarebytes and other similar security software should be able to find, quarantine and remove all the elements securely, which will prevent any reoccurrence of the PUP.

If you'd prefer to do it yourself then there are manual steps that will achieve the same ends.

Hold down the CMD key and press the Space Bar. This will open a Spotlight search bar into which you need to type Activity Monitor and select the matching result.

Next, go to Finder, click on Applications, then search for Mac Auto Fixer. When you find it, drag the app to the Trash.

The last part is to delve deeper into the system to find any remnants that could be lurking in folders.

Navigate to the following folders and drag them to the Trash.

  • /Library/Application Support/Mac Auto Fixer
  • /Library/Application Support/maf

Then look in the /Library/LaunchAgents folder for any files that are for Mac Auto Fixer or MAF, and drag them to the Trash.

Finally, empty the trash, reboot your system, and hopefully you should be rid of the nuisance application.
