    Clean my Mac problems?
    I just read that Clean my Mac is not recommended by some on this forum because it can cause some problems. What kind of problems can it cause?

    Slowdowns...and money out of your pocket to make your computer slower! Both things folks usually don't want.

    p.s. I wanted to add. One of the more common complaints about "Clean My Mac" is it cleans too much. And this seems to lead to computer slowdowns of some sort.

    Have a read of this for problems. Note the comments by the developers and lack of response to many problems.

    Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

    I have used CleanMyMac and Onyx for several years. I never had a problem with either except with the "maintenance" functions in CleanMyMac3 (similar to Onyx, which I never had a problem with). However, I don't use the CleanMyMac "Smart Cleanup" - i go through each section and check what each scan brings up. You can deselect anything that might be a problem, for instance, I use Family Tree Maker, which syncs with ancestry.com. I had a lot of problems with syncing in the past and am afraid of messing this up. Something like that I set in preferences for the scan to skip. As I said, I've never had CleanMyMac mess up my system using any function except maintenance - so I use Onyx for that.

    But you have to use either program properly! It is critical to restart immediately after using these programs - that is when your system integrates the changes. If you don't, your system doesn't know what to do. CleanMyMac can be a very convenient way to find and remove unnecessary stuff if used properly. I agree that there can still be some files left over after an uninstall with CMM - I have used AppCleaner.app and EasyFind.app successfully without problems for this. There are also Terminal command lines you can find from reputable posters in forums and IT blogs. I am not a developer or IT person, but have found posts that have helped me many times.

    It looks to me like people who are having big problems need to learn some basic principles like making regular backups. I use Time Machine for daily backups, or more if I am doing a lot of work. I also make bootable clones with Carbon Copy Cloner monthly, or if i make significant changes to my system. If you spend a little time to learn how to use things, proceed cautiously with small steps when first using a new program or OS, backup frequently so you can restore if something goes wrong, it takes more time at the beginning, but saves a lot of time and aggravation later.

    Also, in the "CMM cleaned too much" link posted above, I don't understand the comment about "lack of response" from CMM developers. They replied to people's concerns in the forum, and made repeated requests for people having problems to contact support - the developers say no one contacted them with the problems described in the forum.

    I have to ask - do you work for the makers of CleanMyMac?
    There literally thousands of complaints about CleanMyMac - here and on Apple Discussions.

    Take the above post from "miz_mdk" with a large grain of salt. They are obviously associated with the app which as member "gsahli" has pointed out has many complaints against it. Besides, the new version CleanMyMac3 is $39.95 to purchase whereas OnyX is free (and safe to use).
