Cleaning your Mac is a necessary task if you don’t want to end up with a slow Mac, and it is an easy task if you’re using a Mac cleanup program. There are several Mac cleaning programs to choose from, so hopefully this review of the software program CleanMyMac, can help you decide if this particular Mac cleaner is the one for you.


CleanMyMac is compatible with Lion OS X, and can be installed on PPC / Intel, Mac OS X 10.4 or later. It installs easily, and says nothing about being a trial version until you go to clean it.  During the review, it found 700+MB in my cache, however, as seen in the below screenshot it only allows a total of 500MB to be cleaned during the trial. It did allow me to use 154MB to clean some smaller areas, but without the license if you have anything over 500MB in one area, such as the Caches, then you won’t be able to clean it.

CleanMyMac Interface

CleanMyMac has a nice layout, even allowing you to change the appearance in preferences if you wanted too. The application is made to be easily usable, even by those that are not very tech savvy. When it first opens there is nothing that tells you what to do next, it would be helpful to have something prompt you to either read the manual or begin cleaning by pressing the scan button.

To start the program you press the Scan button located in the lower left corner, or you can go to Preferences and choose the ‘getting started’ or user’s manual web-page. The scan takes several minutes, much longer than other Mac cleaning programs. However, it does find a lot of unnecessary files and junks.

Features and Cleaning

With almost every application you install come caches, universal binaries, unnecessary logs, files, and languages, install preferences, etc. All of this clutter not only takes up valuable disk space, it also slows down your Mac.

CleanMyMac Features and Functions Allow You To:

  • Clear caches
  • Clean logs
  • Remove unnecessary universal binaries
  • Clean system junk
  • Delete unnecessary language files
  • Empty Trash and get rid of leftovers
  • Uninstall Mac software properly
  • Delete files without leaving any trace
  • Monitor Trash status
  • Clean removable devices from service files
  • Manage built-in widgets, plug-ins and preferences
  • Advanced search filter allows cleaning or exclusion of cleaning of a single item

The functions and features on CleanMyMac are commonly found on other Mac multi-cleaners. Like the other Mac multi-cleaning programs, CleanMyMac is able to remove all of the garbage that is on your Mac.

More Tools:

Some multi-cleaners come with more than cleaning tools, and CleanMyMac is no exception. It does not come with as many extras as some other programs, but it does have a few, including:

Uninstall Applications: This is a recommended way of deleting Mac software, as it makes sure the app was deleted properly and entirely (in opposition to dragging Application file to Trash).

Quick Erase Files: Allows you to delete files without leaving any trace. It doesn’t free more space, it just guarantees that the file will be removed completely.

Manage Extensions: This allows you to explore what extensions are currently installed in your system, and remove those you do not want.


CleanMyMac performed fine, with the only slow part being the earlier noted lengthy scanning process. There is, however, a concern about files or programs becoming corrupted. This is noted on the CleanMyMac web page, and by frustrated users. The fix is to simply reinstall the program, and there is also a way to prevent it as well.


CleanMyMac is a multi-functional cleaning utility that can free up a lot of hard drive space on your Mac. In addition to cleaning tools, it included other utilities that can be useful, such as the uninstaller. CleanMyMac has a simple, easy to use layout that can help keep your Mac clutter free.

The makers of CleanMyMac have made this cleanup utility more user friendly than some others, in that you can co some configuring to the program in Preferences so that it suits your needs better, including the ability to exclude a program from cleaning, or cleaning only that program. This feature alone can help you lower the risk of file corruption, or accidental removal, something most other cleaning programs does not have.

The bottom line is that CleanMyMac can get a lot of garbage off of your Mac, sometimes even more so than other cleaning programs, and although it does have a slightly higher risk of file corruption or removal you shouldn’t let that stop you from using it. Because as long as you use its unique user preferences to add your input, CleanMyMac will be a good cleaning utility for your Mac.
