Many people that download and use MacKeeper experience severe problems as a result. If you have installed MacKeeper and wish to remove it, read on.
Uninstalling MacKeeper 2012
If you have used MacKeeper to encrypt any data, unencrypt it now. If you remove MacKeeper without unencrypting your data first, you will not be able to access it later. This only applies to data encrypted with MacKeeper, and not data encrypted using Mac OS built-in encryption services or using any other program.
Once that is done, you can follow MacKeeper’s uninstall instructions here:
These instructions promise that they will remove all MacKeeper’s associated files (see the note ‘Important’ at the bottom of their page). However, you may wish to do Step 4 in the procedure below for earlier versions of MacKeeper to check MacKeeper does not have access to your Keychain.
Uninstalling earlier versions of MacKeeper
If you have a version of MacKeeper earlier than MacKeeper 2012 you should follow the procedure below. You may not find ALL of the following, but any you do find should be removed.
i. Again, a warning: if you have used MacKeeper’s encryption feature, be sure to unencrypt before you uninstall MacKeeper.
ii. If you use Time Machine, leave it connected and do the Time Machine Step (TM step) where indicated. Instructions for the TM step are given in the box in step 1 below.
iii. If you use a clone without archiving, disconnect the clone and run the procedure below on your internal disk. When it is complete and you have verified everything is OK, connect your clone and wipe the partition using Disk Utility. Then make a new clone.
iv. If you use a clone with archiving, reboot into your clone now and run the procedure below on the clone first. Then shutdown your computer, disconnect the clone from the system and reboot into your internal drive. Run the entire procedure again on your internal drive.
v. If you have anything in the Trash, empty it now before you start.
The Uninstall Procedure:
Once you have prepared everything as above, you’re ready to start the uninstall procedure.
1. If MacKeeper is running, quit it. From the sidebar in any Finder window, choose your hard disk icon and go to your Library folder. Look in the Application Support folder for the folder inside it called ‘MacKeeper’:
Click on the folder once.
If you are using Time Machine do the TM Step now.
Enter Time Machine via the TM icon on your menubar at the top of your screen.
Click the little gear/cog in the Finder window and choose ‘delete all backups of xxx file’.
Enter your Admin password to confirm the delete. Exit Time Machine and then…
If you don’t use TM or after you have completed the TM step, hold down the ‘command’ key and press the ‘delete’ key once to send the file to the trash.
2. Still in Library, look for and trash any of these you find in the same way, remembering if you have Time Machine to do the TM step first in each case:
3. If you are using Lion, use the ‘Go’ menu in Finder’s menubar and hold down the ‘option’ key. Choose ‘Library’ from the menu (yes, this is a different Library folder from the one you were just in). If you are using Snow Leopard or Leopard, just click on the little ‘Home‘ icon in the Finder sidebar and navigate to the Library. Then trash any and all of these that you find, remembering to do the TM step (if applicable) first in each case:
Be careful not to delete the wrong files: only those that have got the words ‘zeobit’, ‘MacKeeper’, ’911′ or ’911bundle’ should be trashed.
4. Go to Applications > Utilities > Keychain Access.app and double click on it. Notice the padlock in the window is up there on the left, rather than down the bottom. Click on it and enter your admin password. Now go through all the items in the ‘Keychains‘ list (such as Login, System, Root) with ‘All items’ selected in the ‘Category’ list. Anything you find related to ‘MacKeeper’ or ‘zeobit’, click on it, then choose Edit > Delete from the menu.
(Thanks to Al for also mentioning this point in the Comments below! ).
5. Open the Activity Monitor utility (Applications>Utilities>Activity Monitor.app), make sure ‘All Processes’ is showing in the drop down menu just over on the right of the dialogue box, then scroll down the list and see if any processes called ‘MacKeeper’, ‘zeobit’ or ’911 bundle’ are still running. Older versions of MacKeeper may have a ‘WINE’ process running, so also look for ‘wine’. Anything you find, click on it and hit ‘Quit Process’ (top left).
6. Go to your Applications folder from a Finder window and select MacKeeper (if you have Time Machine, do the TM step now). Then, hold down ‘command’ and press ‘delete’ once. If you assigned MacKeeper to be pinned in the Dock, be sure to also drag the icon off the Dock and release it anywhere over the desktop. It will, satisfyingly, disappear in the ‘poof’ of a cloud.
7. When you’re done filling up your trash can with all this junk, click on the Finder> Empty Trash.
8. Go to
> System Preferences > Users & Groups (or ‘Accounts’ for Snow L) | Login Items
If you see anything to do with MacKeeper in the list of items there, highlight it, then click the little minus ‘-’ button near the bottom of the list.
9. Restart your Mac. Everything should be back to normal, but check the Activity Monitor one last time to be sure.
**If you are running a clone, remember to follow the instructions given above under “Preparation: Clones”.**
Supplementary: If you have a problem with MacKeeper pop-ups while using your browser, try clearing out the caches, like this:
In Safari menubar, choose ‘Safari > Reset Safari’. Make sure all the options are checked.
This will not only clear out your caches, but everything else stored by the browser. Don’t worry, it won’t affect your bookmarks, but it will reset your ‘top sites’ and history.
In Firefox menubar, choose ‘Tools > Clear Recent History…’ and choose ‘Everything’. Again, it’ll clear everything out but won’t delete your bookmarks.
Obviously, if you use any other browsers like Opera or something you’ll have to find the same options for those too.

1. If you have any problems carrying out the steps, try starting your Mac up in Safe mode, and then running the procedure.
2. You can safely ignore any MacKeeper files that are in the Logs, BOM or Receipts folders.
3. If you have only downloaded the MacKeeper package but not ran the installer, you only need to send the .pkg file in your Downloads folder to the Trash. That’s it!
