What is it and what does it do

Main Functionality

CCleaner, when used correctly, can be a fantastic program. It is a perfect alternative to CleanMyMac, and works almost as efficiently. CCleaner will go through your Mac and delete any files that you no longer need. You can specify before the clean which files you want touched and which files you want left alone. What’s terrific about CCleaner is that is contains no spyware or adware. It is a truly free application.

CCleaner will clean out a bunch of different files. For starters, it will completely clear your browsing history for nearly any web browser you can think of. This is great because these files are where the majority of the clutter on your Mac comes from. In addition, CCleaner will clean out all deleted and temporary files. This will empty your trash and delete log files, error reports, and caches. If all of that wasn’t enough, CCleaner will even go through your registry to make sure you don’t have any unneeded entries.

Now for the horror stories. As with any app like this, it can be dangerous deleting lots of files. There are many users out there who have used this application and gotten terrible results. In most cases, this application would completely reset all of the preferences on your Mac. This can be very annoying as it will reset application license keys, stored application preferences, and even data saved within the application. In addition, it has been reported that it deletes your custom dock, display settings, passwords, and game serial numbers. In one extreme case, it was reported that a user had lost all of his personal data contained in his user folder (which is essentially everything).

Conclusion and download link

Like I said, if you use this app correctly, you will not have a problem. After using it personally, I understand why so many people had bad experiences. You have to be very careful when you are deleting files. If you take it option by option, you should be fine. Overall this application does it’s job and it does it very well. It may be dangerous, but using a little common sense can avoid these issues. If you are not computer savvy, or don’t understand the inner-workings of your computer, then you will probably be better off using a fail-proof application like CleanMyMac.
