Is MacKeeper a Scam in 2018?

MacKeeper by Zeobit, LLC is a multi-functional system utility for Mac OS X which consists of 16 tools for security, system optimization and cleanup. The program has caused much debate and controversy because of Zeobit’s marketing tactics and also because of users reporting that the software itself is actually malware.

Many people in the Mac community ask about the MacKeeper scam. MacKeeper itself is not a scam – it does have a few features that work well. However…

For more than 7 years, I have run my own computer repair company. I have repaired many Macs that have MacKeeper installed. In every case where MacKeeper has been installed, it has been the main culprit of the problem, usually causing performance problems or freezing or crashes.

Despite all the good reviews by professionals, I am personally skeptical about MacKeeper. Even if MacKeeper does its job well for some users, there are a majority who found that the software caused severe problems on their Mac. So, I had to see for myself what MacKeeper is really like.

Find out if MacKeeper is a Scam

Installing the software is a breeze, it’s just an ordinary Apple installer package. Once that is done, you’ll see the MacKeeper icon in your menu bar. MacKeeper has a Helper process which runs in the background all the time and it starts automatically at login. Unfortunately, the Helper uses a lot of memory.

The MacKeeper summary window displays an overview of the tools available.

The first feature I tested was the ‘Fast cleanup’ which identified 624.6 MB of ‘junk’ on a fresh Mac OS X 10.8 install. The bulk of this was removing non-English language translations from applications (an overrated feature because Mac drives are so large these days a couple hundred megabytes doesn’t make much difference). The ‘Fast Cleanup’ feature is quite thorough and gives you a choice of which files to remove. It also worked very best during both the scan and remove stages.

The disk usage feature is similar to that offered by OmniDiskSweeper, providing a column view by default to show the largest files in each directory. The utility offered by MacKeeper is clearer to read than OmniDiskSweeper, and the scan was very quick as well.

The Smart Uninstaller offers a feature akin to that of Windows Add & Remove Programs and also the Uninstaller list provided by CCleaner. It also lists installed plugins in Safari, Dictionary, QuickLook, iTunes, QuickTime and Spotlight – I don’t know of another piece of software which lets you easily remove plugins on Mac OS X.

I tried an antivirus scan which didn’t take too long (on an empty Mac with a fresh install of Mountain Lion), during the scan it used up to 50% CPU. I think on an older Mac system, probably the original Intel Core Duo models, performance may have been hindered during a scan. The MacKeeper Helper process used about 100MB memory during my testing. The MacKeeper application used about 45MB memory.

Uninstalling MacKeeper

Uninstalling or removing MacKeeper completely from your Mac is not an easy task. To say this is genuine software and not malware, ZeoBit has made it very difficult and awkward for the average user to remove the software from their Mac. I have written a guide about how to remove MacKeeper from your Mac.

What Is Missing?

While MacKeeper offers a good set of functionality, I wouldn’t say it’s the best multifunctional tool I’ve ever seen for the Mac. Similar tools usually include Disk Permissions/Disk Repair features, hidden parameter settings and Automation features. I personally prefer Onyx for this.

By using a combination of free tools, you can get the functionality of MacKeeper without the worry that comes with it. While I didn’t have any issues while using the trial version, I cannot ignore the fact that this software has caused problems for several of my customers in the past. If the software is meant to be as good as the professionals say, then ZeoBit needs to improve the reliability and iron out the problems people are experiencing.

  1. MacKeeper is Malware. It is identified as such by several of my antivirus/malware programs. It came up allegedly via apple.com and then rerouted me claiming that I had “severe” issues numbering close to 1900 of them and that I needed to pay them for their services to fix it. This is SOOO similar to a similar fishing scam by another company that froze my Safari multiple times claiming infection and directing me to their “people” who wanted remote access to my computer to id the issue, then wanted almost $300 to fix it, and an additional $250/yr to “make sure it didn’t happen anymore.” What a crock. My CleanMyMac, Avira, and other programs can id trojans, malware, and viruses and clean them just fine without all these huge yearly fees. Went Mac to avoid having to buy several hundred dollars of anti whatever every year for programs that only sometimes work and still resulted in my MS computer landing in shop. Mac has been good to us for the last twelve years – even the old ones that are now ten plus years old.

    The local Mac Doctor has advised me to avoid MacKeeper
    like the plague it is. Every day I receive pop ups to
    enroll in their service. How can I stop them?

    What is your problem?????

  4. Zeobit software has always been a tiny step removed from a scam and frequently crosses the line into being a scam. DO NOT INSTALL. I guarantee you will regret it.

    I do not use MacKeeper since they have always seemed too suspicious to me, especially with all those intrusive ads they seem to like redirecting me to. There are other options that you can find through https://alternatives.co which work better, without the threat of malware hanging over your head.

  6. I have a business that passes personal data and need to demonstrate secure transfer so downloaded mac keeper to check my mac was clean, they identified perfetnight which they said I could buy another ‘technician package’ to remove, I said no, I have now downloaded an app OS Cleaner Master – will thus remove perfetnight which I believe is

  7. Sorry didn’t finish I believe it will damage my mac?
