What CleanMyMac Can Do for You

CleanMyMac Lead Image

Because I work at my Mac on a daily basis, I know that I’m accumulating all kinds of outdated cache files, logs, unused langue files, and junk left over from when I delete an application.

I don’t have time to manually search and delete unused junk on my Mac, and that’s why I’ve been using CleanMyMac for several years now. CleanMyMac is so easy to use that it doesn’t really need an entire article to explain how to use it. Instead, the point of this article is to explain why you should be using CleanMyMac to keep your machine free of unnecessary junk, and even give your Mac a power boost.

CleanMyMac 3.0 (affiliate link) is available for free trial download, and is $39.95 for the license.

What It Does

When you run the basic Smart Cleanup, CleanMyMac goes through your Mac  system like a self-running vacuum cleaner, locating junk files, including un-needed foreign language files, finding temporally stored cache files, old log files, broken preferences files, iOS photo caches, and numerous support files that may not get removed when new files are installed.

To use CleanMyMac, you simply click Smart Cleanup, and the program will do the rest.


Many of these types of files can be located and deleted manually, but what kind of fun is that when CleanMyMac can automate the process.

I run CleanMyMac about once a month, each time it locates several gigabytes of junk in my computer to remove.

Running CleanMyMac on my small 128GB MacBook Air is especially important because if I don’t keep it clean, the MBA easily runs out of memory space.

What Else It Do

CleanMyMac can also remove old mail attachments, useless cache of photo files, outdated backups of your iOS device, broken downloads from iTunes (downloads that don’t finish downloading), old iOS software, and duplicates of iOS apps.

Preview Before Running

I mainly run just the Smart Cleanup process, but there are other cleanups that you need to be careful about triggering. For example, the Uninstaller module can locate old files associated with applications you’ve previously deleted. CleanMyMac can locate those files and delete them for you.

But you want to make sure that applications you’re sending to the trash are indeed applications you no longer need. If you have lots of applications like I do, you can use the Uninstaller feature to first locate older versions of an application. As a I was writing this article, I didn’t realize that I had an older version of CleanMyMac still installed, so I got rid of it.

If you run an update of an application and the update doesn’t replace the current version, but instead trashes the older version and then installs the new version, CleanMyMac will in turn ask if you wan to uninstall the older version completely. But be careful with that. Sometime it can result in files being removed that you don’t want removed. CleanMyMac let me know that they are working on a special “ignore” list of applications to avoid that issue. Usually the uninstall works just fine, but it you’re uninstalling an application in which its system files may be tied to the new version, check with CleanMyMac before doing the clean uninstall.

You can also open the Extensions module in the sidebar and select old extensions in your web browsers that you can either have removed or deleted. When I disabled and deleted  several Chrome and profiles I noticed a difference in the speed of Chrome launching.CleanMyMac Chrome extensions

Security Modules

CleanMyMac also includes security modules such a brute force file Shedder, and Privacy checker that removes your web browser history, online and offline activity, and chat data.

Preferences Settings

One of the marks of a professional application is what preferences settings it includes. CleanMyMac in this area also doesn’t disappoint.

You can set which modules you want to appear in the sidebar, schedule how often you want to run CleanMyMac, and select which applications and files you want CleanMyMac to ignore in the cleaning process.

In the Updates you will want to make sure to enable “Check for updates automatically,” because CleanMyMac frequently gets updated. Nearly every time I run the application, about once a month, an update appears.  This is not an annoyance for me because I want an application like this to be at its best and most updated when I run it.

Give It a Try

CleanMyMac has been in existence for about seven years, and it’s been endorsed by many popular and respected technology websites including The New Web, iMore, iCreate, and MacStories.

If you’re not using this program, I highly recommend downloading it and giving it a try.  You should naturally always have your Mac backed up, and even your most important files backed up to the cloud, just in case CleanMyMac doesn’t perform the way it should or that you erase a file you didn’t intend to.

The developers of CleanMyMac stand behind their product. Their website is  chockablock with explanations of its cleaning modules and other features. And it even includes a manual that you can download.

Let me know what you think of CleanMyMac and if you plan to use.

    I’ll have to give this a try. Always on the cusp of running low on disk space. Anything similar for iOS that you know of?

    Excellent article, but how does it compare with competitors? Is it absolutely perfect or is there other software that is just as effective and less expensive? It’d be nice to see more objective analysis rather than just a commercial for the software.

    • Hi Corbett, thanks for your feedback. A comparison article would be useful. ClaenMyMac as worked well for me that I haven’t thought to look elsewhere. But when I get some time I’ll look into that.

  3. Just ran this and clean up over 30 G on my machine. That’s a ton on this SSD. Great product and features.

  4. Many of Mac users have shared that CleanMyMac didn’t work for them.

    Thanks Bakari for sharing this with us. I am also the luckiest one that CleanMyMac used and worked for me.

  5. I have used this software before for my mac. This software is perfect with its best features.

    Thanks for the info, Bakari. I always enjoy and learn from your postings. CleanMyMac has worked great for me and I’d recommend it to others: very easy to use and worked as advertised with no issues.
