    "CleanMyMac" is a scam and a common cause of instability and poor performance. Depending on what version you have, the developer's instructions may not completely remove it. Please follow those instructions, then do as below.

    Back up all data before proceeding.

    Triple-click anywhere in the line below on this page to select it:

    /Library/LaunchDaemons/com.macpaw.CleanMyMac3.Agent.plist

    Right-click or control-click the highlighted line and select

              Services Reveal in Finder (or just Reveal)

    from the contextual menu.* A folder may open with an item selected. If it does, move the selected item to the Trash. You may be prompted for your administrator login password.

    Repeat with this line:

    /Library/PrivilegedHelperTools/com.macpaw.CleanMyMac3.Agent

    Restart the computer and empty the Trash.

    You may also have to remove one or more of these items in the same way:

    ~/Library/LaunchAgents/com.macpaw.CleanMyMac.helperTool.plist
    ~/Library/LaunchAgents/com.macpaw.CleanMyMac.volumeWatcher.plist
    ~/Library/LaunchAgents/com.macpaw.CleanMyMac3.Scheduler.plist

    Never again install "CleanMyMac" or anything like it.

    *If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select

              Go Go to Folder...

    from the menu bar and paste into the box that opens by pressing command-V. You may not see what you pasted because a line break is included. Press return.

    Thank you So Much !

    I removed Clean My mac 3 completely.

     

    Im checking activity monitor and the only app that is using a significant amount of cpu is in fact Safari. Is this normal? the fans are also working non stop, and is still over heating.

    Is there anything else to do?

     

    What do you recommend to do as a regular maintenance to my mac? I used Clean my mac to get rid of duplicated files, etc. Is there any other way to free disk and memory space?

    Please quit and relaunch Safari after taking each of the following steps that you haven't already tried. Stop when the problem is resolved.

    Back up all data before making any changes.

    Step 1

    The issue can be caused by web pages in the Favorites list that sometimes or always prompt for access with a CAPTCHA. If you know that there are such pages among your Favorites, remove them and see whether there's an improvement. Otherwise bookmark and remove all Favorites, then restore them one or a few at a time until you find the culprits. There may be more than one.

    Step 2

    Triple-click anywhere in the line below on this page to select it:

    ~/Library/Safari

    Right-click or control-click the line and select

              Services Open

    from the contextual menu.* A folder named "Safari" should open. Quit Safari if it's running. One or more files in the open folder should have a name beginning in "History". Move those files, and only those, to the Desktop, leaving the window open. Relaunch the application and test. If there's no change, quit again and put the files you moved back where they were, overwriting the ones that may have been created in their place. Otherwise, delete the files you moved. The browser history will be empty. If possible, restore the deleted files from a backup that predates the problem.

    *If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination  command-C. In the Finder, select

              Go Go to Folder...

    from the menu bar and paste into the box that opens by pressing command-V. You may not see what you pasted because a line break is included. Press return.

    Step 3

    Open the iCloud preference pane and uncheck the box marked Safari. Test. Then check the box again, if you wish.

    How to maintain a Mac

    Make two or more backups of all your files

    One backup is not enough to be safe. A copy of a backup doesn't count as another backup; all backups must be made directly from the original data.

    Keep at least one backup off site at all times in case of disaster. Backing up to a cloud-data service is one way to meet this need, but don't rely exclusively on such backups.

    In fact, don’t rely on any single backup method, such as Time Machine.

    If you get an indication that a backup has failed, don't ignore it.

    Keep your software up to date

    In the App Store or Software Update preference pane (depending on the OS version), you can configure automatic notifications of updates to OS X and other Mac App Store products. Some third-party applications from other sources have a similar feature, if you don’t mind letting them phone home. Otherwise you have to check yourself on a regular basis.

    Keeping up to date is especially important for complex software that modifies the operating system, such as device drivers. Don't install such modifications unless they're absolutely necessary. Remove them when they are no longer needed. Before installing any Apple update, you must check that all system modifications that you use are compatible. Incompatibility with third-party software is by far the most common cause of difficulties with system updates.

    Don't install crapware

    ...such as “themes,” "haxies," “add-ons,” “toolbars,” “enhancers," “optimizers,” “accelerators,” "boosters," “extenders,” “cleaners,” "doctors," "tune-ups," “defragmenters,” “firewalls,” "barriers," “guardians,” “defenders,” “protectors,” most “plugins,” "virus scanners,” "disk tools," or "utilities." With very few exceptions, such stuff is useless or worse than useless. Above all, avoid any software that purports to change the look and feel of the user interface.

    It's not much of an exaggeration to say that the whole "utility" software industry for the Mac is a fraud on consumers. The most extreme examples are the "CleanMyMac," "TuneUpMyMac," and “MacKeeper” scams, but there are many others.

    As a rule, you should avoid software that changes the way other software works. Plugins for Photoshop and similar programs are an obvious exception to this rule. The Mac App Store has extensions for the Photos app, and perhaps others, that should be safe. Safari extensions, and perhaps the equivalent for other web browsers, are a partial exception. Most are safe, and they're easy to get rid of if they don't work. Some may cause the browser to crash or otherwise malfunction. Some are malicious. Use with caution, and install only well-known extensions from relatively trustworthy sources, such as the Safari Extensions Gallery.

    Only install software that directly enables you to do something that you need the computer for. For example, a word processor enables you to write. A video editor enables you to make movies. A game enables you to have fun. But a "cache cleaner"  or a "malware scanner" doesn't enable you to do anything. You didn't buy a computer so you could clean caches or scan for malware. Just say no to anyone who wants you to do such things.

    Never install any third-party software unless you know how to uninstall it. Otherwise you may create problems that are very hard to solve. Do not rely on "utilities" such as "AppCleaner" and the like that purport to remove software.

    Don't install bad, conflicting, or unnecessary fonts

    Whenever you install new fonts, use the validation feature of the built-in Font Book application to make sure the fonts aren't defective and don't conflict with each other or with others that you already have. See the built-in help and this support article for instructions.

    Deactivate or remove fonts that you don't really need to speed up application launching.

    Avoid malware

    "Malware" is malicious software that circulates on the Internet. That kind of attack on OS X was once so rare that it was hardly a concern, but it's now increasingly common and dangerous.

    There is some built-in protection against malware, but you can’t rely on it—the attackers are always at least a day ahead of the defense. You can’t rely on third-party "anti-virus" or "anti-malware" products for protection either. The only safety lies in safe computing practices. The "anti-virus" industry will always try to persuade you that you're helpless to protect yourself from malware attack unless you use its products. You're not helpless—rather, that industry is helpless to protect you, just as it's helpless to protect Windows and Android users, whose platforms are infested with malware despite the fact that they spend $75 billion a year on "anti-virus" software.

    Never install software from an untrustworthy or unknown source. If in doubt, do some research.

    Any website that prompts you to install a “codec” or “plugin” that comes from the same site, or an unknown site, is untrustworthy.

    A stranger on a website who is strangely eager for you to run a free application, and won't take no for an answer, is untrustworthy. What's in it for him?

    Software that doesn't come from the Mac App Store, such as Adobe Flash Player, must come directly from the developer's website. No intermediary is acceptable, and don’t trust links unless you know how to parse them.

    Any file that is automatically downloaded from the web, without your having requested it, should go straight into the Trash.

    A web page that tells you that your computer has a “virus,” or that anything else is wrong with it, is a scam.

    In OS X 10.7.5 or later, downloaded applications and Installer packages that have not been digitally signed by a developer registered with Apple are blocked from loading by default. The block can be overridden, but think carefully before you do so.

    Because of recurring security issues in Java, it’s best to disable it in your web browsers, if it’s installed. Few websites have Java content nowadays, so you won’t be missing much. This action is mandatory if you’re running any version of OS X older than 10.6.8 with the latest Java update. Note: Java has nothing to do with JavaScript, despite the similar names. Don't install Java unless you're sure you need it. Most people don't.

    Don't fill up your disk or SSD

    A common mistake is adding more and more large files to your home folder until you start to get warnings that you're out of space, which may be followed in short order by a startup failure. This is more prone to happen on the newer Macs that come with an internal SSD instead of the traditional hard drive. The drive can be very nearly full before you become aware of the problem.

    While it's not true that you should or must keep any particular percentage of space free, you should monitor your storage use and make sure you're not in immediate danger of using it up. According to Apple documentation, you need at least 9 GB of free space on the startup volume for normal operation.

    If storage space is running low, use a tool such as OmniDiskSweeper to explore the volume and find out what's taking up the most space. Move seldom-used large files to secondary storage.

    Relax, don’t do it

    Besides the above, no routine maintenance is necessary or beneficial for the vast majority of users; specifically not “cleaning caches,” “zapping the PRAM,” "resetting the SMC," “rebuilding the directory,” "defragmenting the drive," “running periodic scripts,” “dumping logs,” "deleting temp files," “scanning for viruses,” "purging memory," "checking for bad blocks," "testing the hardware," or “repairing permissions.” Such measures are either completely pointless or are useful only for solving problems, not for prevention.

    To use a Mac effectively, you have to free yourself from the Windows mindset that every computer needs regular downtime for maintenance such as "defragging" and "registry cleaning." Those concepts do not apply to the Mac platform.

    A well-designed computing device is not something you should have to think about much. It should be an almost transparent medium through which you communicate, work, and play. If you want a machine that needs a lot of attention just to keep going, use a PC, or collect antique cars.

    The very height of futility is running an expensive third-party application called “Disk Warrior” when nothing is wrong, or even when something is wrong and you have backups, which you must have. Disk Warrior is a data-salvage tool, not a maintenance tool, and you will never need it if your backups are adequate. Don’t waste money on it or anything like it.
