MacKeeper review: We’ve tested it for you

MacKeeper is a Mac cleaning application by Kromtech Alliance. According to the developer, the app has over 60 million Mac clients using it. Without going into a long discussion about MacKeeper’s trustworthiness and business ethics, we’ll have an honest look at MacKeeper’s features. This application is full-packed with various Mac optimization tools.

The interface

Right after installing MacKeeper, you’ll see its trademark robot figure. This aims to show an automated approach to Mac cleanup; at the same time, MacKeeper lets you talk to a real human via live support, the link to which you’ll find in the top right corner. The whole right panel looks like a giant chat window. This space MacKeeper uses to sell you extra features and other add-ons. 

The interface is pretty clean (for a cleaning application), with all the utilities placed in the sidebar to the left. The icons were easy to grasp as well as the names of the features themselves. On a different note, you’ll notice the abundance of pop-ups and dialogue boxes that constantly cry for your attention.

Before you get to clean anything, you got two main routes to choose from: either follow an automated cleanup script or start cleaning things manually. The latter option is good for experienced Mac users. The automated route is called Find & Fix mode.

What are the main MacKeeper features?

As I said earlier, MacKeeper features are so many that it is wrong to keep calling it a “Mac cleaner.” For example, it has a VPN tool, a tracking service, an ad blocker, etc. This makes it a swiss-army knife type of program for universal Mac maintenance. But before you get lost in the many options, here are some most prominent ones:

  • Safe cleanup
  • Duplicates finder
  • Memory cleaner
  • Update tracker
  • Login item manager
  • Smart uninstaller
  • Device tracker
  • Private connect tool
  • Ad blocker utility

Find & Fix: A guided cleanup 

MacKeeper suggests to automatically scan your Mac for issues with a feature it calls Find & Fix. This option is conveniently placed at the top above other elements. The scanning algorithm in Find & Fix goes through 4 consecutive steps:

  1. Cleaning
  2. Performance
  3. Privacy
  4. Security 

Just as I tried to run my first scan, I was asked to give MacKeeper Full Disk Access in System Settings. This resulted in a few extra clicks, and I couldn’t go further without restarting the app — a rather cumbersome experience.

The scanning process took about 10 minutes on my 512 GB MacBook Pro 2021. The app found 577 MB of junk files I could delete. Interestingly, MacKeeper’s alternative, CleanMyMac X, found almost 5 GB of system junk. 

MacKeeper also detected two adware threats, although only one of them was displayed — another Mac cleaning tool it deemed potentially unwanted. 

Bear in mind that MacKeeper is a paid application, so in order to remove any items, you’ll have to pass through a paywall. Still, there were a couple of free tools that I was able to use in the trial version. One of those is Safe Cleanup, which belongs to the next group of utilities called Cleaning.

MacKeeper review: Performance tools

MacKeeper sports a RAM cleaner tool that shows occupied memory in real time. By pressing “Memory Cleaner,” you flush the occupied memory slots, releasing some fresh memory. This, in theory, should unfreeze some memory-demanding program that has hung up. However, to use it, you’ll have to create an account and buy a subscription. 

Within the same group of tools, you’ll notice the Update Tracker, which I found to be a bit out of place here since it doesn’t directly affect Mac performance. With this tool, you can update many apps at once, given that you bought the paid plan.

The app used to have Apps & Processes tab within the same group of tools. However, in newer versions, it was removed. So, the only way to somehow affect the performance of your Mac is to use the Login Items service found here. Unlike other utilities, I could remove an item the app labeled as useless without purchasing the paid plan or creating the account.

Security and Privacy features

MacKeeper takes Mac security seriously, which becomes obvious if you look at the sheer number of its security features. Here, you have an Antivirus and an Adware Cleaner. You can even check your email account for potential data leakage in the Privacy section (ID Theft Guard). For example, according to MacKeeper, my email has been leaked 40 times. Wow, that’s impressive! Immediately after I submitted by email for the check, I received a foggy email about “Protecting my password” with MacKeeper. At that point, I decided to stop experimenting with that feature.

According to the developer’s site, MacKeeper is able to detect spyware and viruses. Unfortunately, I could neither confirm nor deny this, as MacKeeper found 0 viruses on my Mac. According to Wikipedia, MacKeeper’s antivirus relies on Avira’s anti-malware database, which adds some weight to its security tool pack.

Is MacKeeper safe?

In the past, MacKeeper was known to be associated with the infamous “Your Mac is infected” messages. Though the company distanced itself from such tactics, MacKeeper’s safe status remains controversial. For example, Malwarebytes considers MacKeeper a “potentially unwanted program” or PUP. On the other hand, according to MacKeeper’s website, it has its own anti-malware lab that studies “new and unknown threats affecting Mac.”

If you’re in doubt as to whether MacKeeper is safe to use on your Mac, you may consider some of its best-known alternatives.

The best-known MacKeeper alternatives

CleanMyMac X by MacPaw is another Mac cleaning solution and one of the oldest cleanup tools on the market. CleanMyMac X is an app that is notarized by Apple. Notarization is a process that confirms that an app is free from malicious files.

Here is a detailed MacKeeper review that compares its features with CleanMyMac X.

CleanMyMac X has a couple of Mac cleaning tools that MacKeeper lacks. For example, there is a space visualization tool, Space Lens, that builds an interactive map of your storage.

You can download a free demo of CleanMyMac X here from the developer’s site and start using its modules without creating any accounts.

That was our take on MacKeeper — one of the most talked-about apps in the Mac world. In this MacKeeper review, I’ve covered its features and also touched on the question of whether MacKeeper is safe. Though I’ve been fiddling around with a free trial, you may get a paid version to get the real gist of it. Its yearly plan for 1 Mac costs $119.40. Or you may consider alternative cleaning solutions for your Mac.
