MacOS has a reputation for being a low-maintenance, snappy and reliable operating system. In our experience, that’s largely true. However, even mighty macOS can fall victim to accumulated digital junk clogging up its pipes. 

This is why there are several paid and free utilities for Apple’s line of computers which promise to give your Mac a good scrubbing. We decided to try popular apps such as CleanMyMac and CCleaner for Mac to see if there’s any real benefit to these utilities.

    CleanMyMacX is a paid package that offers a long list of benefits as well as a few pretty bold claims about performance increases.

    CleanMyMacX has three main components. There’s the system file cleaning part, which looks for orphaned and redundant data, letting you delete it. This even includes deeply-embedded stuff such as localization data that’s not relevant to you.

    The second part of the application is an anti-malware scanner. Many readers might find this surprising thanks to the persistent myth that Macs don’t have viruses. The truth is that the only thing that protected Apple computers from viruses, trojans, worms and other digital nasties was obscurity. With a rapidly growing user base, it’s now worth the time of malware makers to target these machines, so having a scanner isn’t the worst of ideas. 

    The final part of the package is  performance enhancement, monitoring and tweaking. 

    The specific claims made by MacPaw is that you’ll get 4x faster boots, 2.5x more responsive apps and 5x the amount of free space you’d otherwise have, based on their testing with a 2016 MacBook Pro 15. With our 2019 MacBook Pro 13 it’s hard to say that anything has changed performance-wise. It already booted up in a flash and rebooting is such a rare occurrence on modern computers it hardly makes any difference.

    What we will say is that CleanMyMacX is utterly comprehensive, it centralizes management of your system in a slick way and it recovered a significant chunk of free space on our cramped 128GB MacBook Pro. So, it’s well worth the money in our opinion.

    – 100% Comprehensive
    – Freed up a ton of space
    – Very easy to use
    – Makes tasks such as uninstalling apps easier
    – One-off and annual plans available

    – Not really obvious whether performance has improved.
    – It didn’t find malware, but we have no way of knowing if that’s accurate.
    System Cleanup
    Anti-malware Scanner
    Performance Optimization


    Though the program is not free, it’s been around for a long time and has a good track record. Overall, we recommend using it if you prefer cleaning up your Mac without reformatting.


    Stellar Speedup Mac

    Speedup Mac is another paid package, but you can try it for free before buying. Unlike CleanMyMac X, Speedup doesn’t offer any anti-malware functionality. What it does promise is that you’ll have more free space and a faster Mac. 

    It has various ways to achieve that goal. These include looking for duplicate files, identifying large files you might not know about and analyzing which startup and third-party apps you don’t use. It also targets unused language files, Mac trash files and other similar loose bits and pieces.

    This all sounds pretty good, but after signing up for the free trial, giving up our credit card information and downloading the application in the link sent to us via email, we were hit with an error message.The application needs to be updated to work with the latest version of macOS Catalina. So we had no choice to cancel the trial and move on.


    • None.


    • The application wouldn’t install on macOS Catalina.
    • No option for a once-off purchase.

    CCleaner for Mac

    CCleaner is a popular and trusted system cleaner app on the Windows side of the fence, but many people may be surprised to know that there’s also a Mac version. We’re only looking at the free version here as an alternative to the paid applications we’ve looked at so far. 

    The free CCleaner for Mac focuses on two things. The first is to make your computer faster and the second is privacy protection. The paid version adds real-time monitoring, automatic updates and premium support.

    We loved this little app and it worked just as advertised. The free version is light on features compared to something like Clean My Mac X, but for the average Mac user who wants a good free solution or perhaps for schools that run labs full of Macs, it doesn’t really get better than this.


    • It’s free.
    • It works just fine.


    • Not particularly attractive.
    • Middle of the road user-friendliness.

    All of the apps we’ve looked at so far are packed with multiple features, trying to attract you by offering a veritable buffet of optimization gimmicks, so we thought that something like AppCleaner could be a simple alternative. This little applet does one thing and one thing only; it uninstalls applications properly.

    The way it works is dead simple, at least from the user’s perspective. Simply drag an app you no longer want into AppCleaner and it will find and list all the files associated with the app across your hard drive. Then, after reviewing those files, you simply click a button to delete them all. 

    The main downside here is that it’s of little help for apps that have already been removed and left their crud all over your computer. However, it helped us remove apps that we had tried to uninstall, but still had their icons cluttering up Launchpad. Now they’re gone and all it took was a click or two.


    • It does one thing and it does it well!
    • It’s free!


    • It only does one thing, but again it does it well!

    Do Cleaning Apps Really Do Anything For a Mac?

    This is a very difficult question to answer, because your computer’s performance in day-to-day desktop tasks can be very subjective. These cleaning apps are unlikely to make much difference in benchmarks and in the age of solid-state storage it really doesn’t matter how jumbled up the actual data is, since it can be read from any location instantly.

    Where does that leave the utility of these cleaning applications? Well, one major area where they help is in freeing up disk space. Modern MacBooks in particular have pretty tiny system drives.128GB and 256GB disks aren’t uncommon, which means you could run out of disk space pretty quickly. What’s worse, it’s not always obvious in MacOS where that space is being consumed.

    From that point of view we really can recommend these junk cleaning apps as a fast and convenient way to remove typically unneeded files. You could do it manually, but that would take ages and require precise knowledge of where to look.

    Is an application like CleanMyMac or CCleaner safe? There is no such thing as a perfectly safe application, so there’s always the chance that these apps will delete something important or otherwise interfere with the normal functioning of your Mac. This is why you should always maintain a recent backup using Time Machine or the backup software of your choice.
