What CleanMyMac Can Do for You

Because I work at my Mac on a daily basis, I know that I’m accumulating all kinds of outdated cache files, logs, unused langue files, and junk left over from when I delete an application.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

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 Does

CleanMyMac can also remove old mail attachments, useless cache of photo files, outdated backups of your iOS device, broken downloads from iTunes (downloads that don’t finish downloading), old iOS software, and duplicates of iOS apps.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

CleanMyMac lets me know that it’s working on a special “ignore” list of applications to avoid that issue. Usually the uninstall works just fine, but if 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.

I highly recommend giving CleaMyMac a try.  You should naturally have your Mac backed up regularly, and even have your most important files copied to or stored in the cloud, just in case CleanMyMac doesn’t perform the way it should, or if you accidentally erase a file.

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.

CleanMyMac On Setapp

You can download CleanMyMac for a free trial directly from its website, but I suggest you download CleanMyMac from Setapp, which consist of a suite of handpicked Mac applications that you can review and download by simply opening a Setapp account. (Discloser: I’m an Setapp affiliate. The applications I recommend ones that I currently use or have tried out and recommend for other Mac users.)

You can try out Setapp for free 7-day trial, which means you can not only try out CleanMyMac for a month, but there over a hundred other apps you can download and try out as well.

You don’t have to provide a credit card to register for Setapp. At the end of your month trial, you can sign up for a $9.99 subscription, which gives you access to CleanMyMac and all the applications in the suite. More applications get added to Setapp on a regular basis.

Setapp has 111 apps, from 94 vendors, worth a total of $3,127.82 as of today, and the number of apps keeps growing.

If you purchase ten of the applications separately outside the Setapp suite, you’d easily pay a few hundred dollars, but with the subscription, you pay less over time.

Here’s my longer review of Setapp. Let me know what you think of Setapp and CleanMyMac.

  • 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.

  • 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.

  • 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.
