Why Choose MacKeeper

MacKeeper is a tool that has put ease of use front and center in its product offering. The tool features a variety of different tools that are together designed to ensure that MacOS computers run as fast and efficiently as possible. Mac users are used to dealing with a smaller selection of security and cleanup products than exist in the Windows world. Tracking down different components can be difficult. With MacKeeper, users can install just one program and benefit from an enormous range of utilities including a VPN, a privacy scanner, a cleanup utility, and a memory cleaner. MacKeeper promises to offer everything needed to keep a MacOS computer safe—and more

What MacKeeper Offers

Cleanup tools

  • Junk file remover
  • RAM inspector and smart shutdown utility
  • Duplicate scanner and remover

Antivirus and system protection

  • Antivirus
  • ID theft prevention system
  • Live chat integrated into scanning tool


Find and Fix

MacKeeper’s find and fix utility scans the entire Mac filesystem in order to identify security threats as well as things that might be impairing system performance such as duplicate files and leftover caches from browser activity. Although many users prefer to dive deep through the program’s settings and individually perform security and cleanup scans, the Find and Fix utility gives users a quick and easy means of applying a multitude of system fixes and performance enhancements in one go.

Deep System Clean

The longer computers are used the greater the chance that they will be harboring a significant amount of junk that could impair system performance. Besides duplicate files these could include things such as files that browsers store to speed up operation, email attachments that were stored offline, and other files and folders that may have been useful once—but which are simply taking up space now. By using the deep system clean utility, users can quickly scan the system for these files. The results of the scan are presented prior to any automatic deletion occurring so that users can ensure that the system is only eradicating those files which are not truly needed


Of course, at its core MacKeeper features an antivirus scanning engine. Despite popular perceptions, MacOS systems are routinely targeted by viruses and malware and MacKeeper maintains an up to date definitions database which is designed to spot these on the system. The antivirus component of the product protects users’ computers from:

  • Malware
  • Viruses
  • Adware attacks

Track My Maс

MacKeeper also integrates with iOS-running mobile devices in order to help users find their devices in the event that they are lost or stolen. The Track My Mac feature allows users to track their iOS device while it is lost. Users can also remotely take a photo through the device’s camera. As this is instantaneously captured remotely this can be useful evidence in the event that the thief is captured red handedю

Memory Cleaner

Mac memory can quickly become bogged down with startup processes and other things running in the background that do not need to be there. MacOS allows users to both cut down on unnecessary background clutter and also to forcibly close programs that are running in the background. Together, these 2 strategies can significantly boost system performance and speed up laggy systems.

Smart Uninstaller

After taking care of the main system junk there are still plenty of fragments lying around the system—including things like previous installation executors that are no longer needed, unwanted widgets, and Mac plugins that are not actually doing anything. MacKeeper’s Smart Uninstaller is the final line of defense against bloatware and system clutter and can automatically detect files that are unlikely to be wanted or needed and quickly remove these from the system. Again, users are informed before any actual deletions take place.

VPN Private Connect

MacKeeper includes a built-in VPN tool in order to help Mac users use a secure encrypted connection when accessing any page where sharing their personal information might be unsafe. The VPN can also be configured to be connected all the time. 

Ease of Use

Thankfully getting your Mac clean is an easier process than might be expected. Users can initiate the complete cleanup routine by initiating the Find and Fix utility. Additionally users can remain in constant contact with the MacKeeper team through a sidebar communication window located next to the scanning display bar. 

Detection Rates and Reliability 

The main negative about MacKeeper is that we were not able to source any independent benchmarking data to assess just how good the tool is at detecting MacOS viruses and malware. Although the Mac antivirus world is certainly smaller than the Windows ecosystem we found this slightly concerning. 

Nevertheless, despite the third party validation, we did find that the tool was competent at detecting a variety of test samples used during the testing process. Additionally the program has been downloaded more than 50 million times to date according to the website with plenty of happy users enjoying the product to keep their Mac device safe. 


Users can use the tool for free if they are happy to only have the system scan for viruses and other system problems. However in order to access the removal functionalities then users will have to upgrade to a paid plan. 
The service can be subscribed to month to month or for a 24 month plan. If users commit to the service for 2 years then the monthly cost drops to just $4.95

Subscription Period1 month6 months12 months24 months
Price$14.95$9.94 per month$7.95 per month$4.95 per month
BillingMonth to monthIn one sumIn one sumIn one sum

Value for Money 

In order to maximize their value for money users would clearly be best advised to opt for the 24 months plan where they can get the program for less than $5 per month. In terms of the tool’s value for money, given that it includes both cleanup and antivirus features it represents a very good deal. For users that want to take the system even further and also make good use of the VPN it is an even better price. 

Help and Support 

MacKeeper promises its users 24/7 support through a live chat functionality that is baked into the product. This gives users quick access to a product expert that is able to advise upon the best scanning and cleanup methodologies to use to get their system in good running order. Some users have reported that getting assistance can take a little time so patience is advised. In terms of online self help resources this is one domain in which the MacKeeper team could do a bit better as we did not find a plethora of documentation available to help make best use of the solution. 

Bottom Line

Overall, MacKeeper contains a lot of functionality for Mac users that don’t want to have to go on a shopping spree just to find the tools required to protect their device and keep it running at good speed. While the lack of external benchmarking was a negative, there are plenty of features packed into the tool to help prevent age-related slowdown and ensure that Mac devices are protected against adware, viruses, and other threats.
