We are decidedly not impressed with MacBooster. Ok, we’ll put aside the general complaint that apps like this do very little if anything to improve performance (in fact, in our tests, we find almost always quite the opposite). We have a bigger beef with MacBooster.
Indeed, we rate it even more pesky than it’s obvious inspiration: MacKeeper…😳
Aside from the fact that MacBooster’s uninstaller leaves a number of executables and other binary files hidden on the user’s system, there’s also the rather cheeky use of ‘com.apple.UninstallerAD” as a bundle identifier in their uninstaller app.
I really don’t think the folks at Cupertino are going to appreciate that, but more importantly the use of a misleading bundle identifier reveals a lot about the developers’ intentions.
Meanwhile, whether you use our apps or not, steer clear of MacBooster.
If you’d rather dig it out yourself than use DetectX, here’s the list of paths we have so far:

UPDATE: Please also see How To Troubleshoot Your Mac with FT2.
There can be various reasons why your Mac starts running slowly. Some of these can be app-related – especially if you are making multiple changes in programs that have autosave enabled. Other problems could be due to running processor-heavy apps that need more RAM than you’ve presently got. Before you dash off to Crucial to check out your RAM upgrade options, here’s a few basics to run through:
1. Applications > Utilities > Disk Utility.app
How old is your HDD drive? Click on the top-most hard disk icon in the left column and check the S.M.A.R.T status at the bottom right of the window. Does it say ‘verified’? If it says anything else, back up all your important data and start thinking about buying a new hard disk. If the S.M.A.R.T status is verified, have a look at how much space you’ve got left. A nearly-full disk will slow you down. Generally, it is recommended that you have at least 10% free, but I’d work on getting that closer to 25% for optimum performance. If you have less than that, think about what can be archived onto a backup disk (or two..), such as photos, movies, and even your songs.
2. Applications > Utilities > Activity Monitor.app
What’s using all the CPU time? Is it something you need to be running? Select any obviously unnecessary resource hogs and hit ‘Quit Process’.
3. > System Preferences > Users & Groups
How many apps are in your ‘Login Items’? Remove anything that is not absolutely necessary at start up time.
4. Have you downloaded MacKeeper or other Anti-virus software?
If so, remove it.
5. How recently did you upgrade to Lion and are you using Time Machine?
If you’ve only recently upgraded in the last day or so, or turned your Mac off not long after upgrading, perhaps Spotlight is still indexing (indicated by a dot in the middle of the ‘spyglass’, top right of your screen) or TM is still updating (indicated by the TM indicator spinning in the menubar). Either or these will eventually finish and return your system to (about) normal, but you should let your system run (leaving it in ‘Sleep’ mode will do the trick) for at least 24 hours if you’ve only just upgraded.
6. Did you repair system permissions after upgrading?
Even though the Lion installer should fix system permissions after an upgrade, if you then added any other 3-rd party apps or restore something from Time Machine, repairing permissions is always a good idea. Doing so is harmless, and rules out permissions as a possible factor of poor performance. Do Step 4 here. Unless any are indicted in red type, don’t panic about the permissions errors that come up in the ‘details’ window – many of these can be safely ignored.
7. Clear out your caches
Caches, in general, help to speed your computer up. However, if you’re a heavy internet browser and you’ve never cleared your caches or your history (I mean like in several months), then this is worth doing from time to time. You can clean out Internet caches in Safari or Firefox by choosing Safari > Empty Cache or Firefox > Tools > Clear Recent History > Everything. Your computer has other caches that can usefully be cleared out periodically, too: use OnyX to do so.
8. Is the system slow with just one particular program or while trying to open some particular window?
A couple of things could be going on here. If its your browser, try killing some of those extensions/add-ons – every one of them slows you down just that little bit, and many slow you down a lot. Another possibility is a corrupt ‘plist’ or preference file associated with a particular app. Curing this is a bit more tricky and requires knowing your way around the hidden Library folder. If you think this is your problem, leave a comment below to get further instructions.

If you’re unfamiliar with the reputation of MacKeeper but have come here because you downloaded it – or it downloaded itself after you were inadvertantly redirected to some unwanted website – and are now wondering whether you made a mistake, let me present you with a few facts.
MacKeeper is one of the most infamous pieces of software on the macOS platform. This post itself was first published in September 2011, and has since received over 2 million hits from people wishing to uninstall MacKeeper from their computers.
When I ran MacKeeper’s free trial version on a brand new clean install of macOS, it told me that my system was in ‘serious’ condition and that I needed to buy MacKeeper in order to solve all my problems.
It seems, then, that MacKeeper thinks macOS, freshly installed, is a poor piece of software engineering, but the feeling is mutual. macOS doesn’t like MacKeeper much either. macOS provides the following warning about MacKeeper:
MESSAGE FROM CONSOLE
12/05/2015 17:48:00.946 com.apple.xpc.launchd: (com.mackeeper.MacKeeper.Helper) This service is defined to be constantly running and is inherently inefficient.
If you have installed MacKeeper and wish to remove it, read on.
i. If you have used MacKeeper’s encryption feature, be sure to unencrypt before you uninstall MacKeeper. You should also check whether any of your personal files are stored in /Documents/MacKeeper Backups.
Backups & other disks
ii. If you have any disks connected to your mac, including Time Machine, eject them before you start the uninstall procedure.
iii. If you have anything in the Trash, empty it now before you start.
You are now ready to uninstall MacKeeper.
The Easy Way
As I’ve been involved in helping people uninstall MacKeeper for over 5 years, I eventually got round to the task of automating the process so that folks who were not that technically proficient with computers could take advantage of the information on this page.
If that sounds like you, then the easiest way to uninstall MacKeeper is to use my app DetectX. This is a shareware that can be used for free 😀. You do not need to sign up to anything, subscribe to anything or give anyone your email address. Just download the app, run it, remove MacKeeper and be on your way.
After several years of testing and refining my app’s removal procedure, I now recommend using it even for proficient users as it is simply faster, more reliable and less prone to error than doing it any other way. The only people who should really consider the manual option are those that are running versions of macOS that are too old to run DetectX.
Please note also that the list of filepaths below is somewhat out of date. Follow the instructions, but consult my post here for the most recent update to the list of MacKeeper filepaths.
The Manual Way
If you need to remove MacKeeper manually then follow these instrutions carefully. They’ve been refined over the years by many people who contributed in the hundreds of comments that follow this post and have been proven to work without exception. However, bear in mind that the onus is on you to follow the instructions to the letter. For that reason, go slow, read carefully and don’t do anything if you’re not sure what you’re doing. If you have any doubts, post a question in the comments.
Here we go!
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’:
Drag this folder to the Trash.
2. Still in Library, look for and trash any of these you find in the same way:
3. If you are using OS X Lion 10.7 or later, 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:
Be careful not to delete the wrong files: only those that have got the words ‘zeobit’, ‘MacKeeper’, ‘911’ or ‘911bundle’ should be trashed.
Update May 2015:
Due to recent changes in MacKeeper, the following files should also be searched for and removed:
~/Library/Application Support/MacKeeper Helper
The last item above will require removal in Terminal or turning on of invisible files in the GUI (various 3rd party apps can do this, including my own DetectX and FastTasks 2).
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). In 10.10 Yosemite or later, select the View menu and choose ‘All Processes’. For earlier versions of macOS, select ‘All Processes from the drop down menu just over on the right of the dialogue box. Next, scroll down the list of items shown 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 the ‘Quit Process’ or ‘X’ button (Yosemite) in the top left corner.
6. Go to your Applications folder from a Finder window and select MacKeeper. 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 Leopard) | 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.
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 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!
4. If you are seeing ads on this site, we recommend that you use an adblocker!
