With the last seven days of July upon us, the suspense is just killing some people waiting for the release of Apple’s latest version of OS X, 10.8 Mountain Lion. While rumours abound for just about every conceivable day left being the ‘official’ release date (with the 25th being the most popular, it seems), the sensible are making sure they’re prepared. So here’s a few things to do both before and on the big day:
1. Check the tech specs
Check out the tech specs for Mountain Lion and the list of supported machines to make sure you can run it on your current system. If you are upgrading from Snow Leopard, you should also check out will my old apps work with Lion?.
2. Run Software Update
Make sure you have the latest version of everything by running
> Software Update
before you upgrade. This will help to cut down any compatibility problems when installing Mountain Lion.
3. Backup your current install
Without a doubt the biggest cause of trouble and frustration with every OS release is among users who didn’t backup their systems before trying to install the new one. Like Lion, Mountain Lion will be delivered as a download from the App Store, and while this method is certainly convenient, corrupted downloads are not uncommon. Moreover, even when the install proceeds as expected, you want to be able to get back to your previous system if you find things are not to your liking. An OS installation is like performing major surgery on your computer and the chances of complications are always a significant risk. As the old boy scout saying goes ‘Be Prepared’. Backup, backup, backup.
4. Remove everything from your Login Items.
For Lion users, that’s
> System Preferences…> Users & Groups | Login Items
If you’re upgrading from Snow Leopard 10.6.8, go to
> System Preferences…> Accounts | Login Items
There’s a couple of reasons for doing this, but mainly it’s to ensure that you can log in without difficulty. Login Items are one of the main causes of OS problems at the best of times, but with a major upgrade like this, you don’t want any incompatible software choking the system from booting up. See Steps 8 & 9 below about re-activating your Login Items after the installation.
5. Uninstall AV software & other utilities
If you have Sophos, VirusBarrier, iAntiVirus, F-Secure, or similar uninstall these prior to upgrading. After upgrading, if you must use them, look for updates. Uninstall MacKeeper, Little Snitch, LogMeIn or any other 3rd party utility that runs prior to user login.
6. Be prepared for slow download times
Apple’s servers will be hotter than a forest fire on release day, so you can expect download times to be pretty poor. At the very least, connect your computer to your router via ethernet cable rather than wifi – that’ll at least help push things along a bit faster at your end. If you can do it from the office or somewhere else that has a lot more bandwidth than the usual home connection, do so.
7. Save the installer
After the download completes the installer will run automatically. Do NOT click ‘Install’, but instead quit it. Then go to your Applications folder and copy the ‘Install OS X Mountain Lion .app’ and save it to your Downloads folder or somewhere else. Then you can run the installer in your Applications folder.
The reason for doing this is that when you install Mountain Lion the Install app in your Applications folder will self-delete. If the install shouldn’t work for some reason the first time round, you won’t have to go through the whole tiresome wait of a download from the App store again if you save a copy to your Downloads folder.
8. Update 3rd-party apps
Assuming Mountain Lion boots up just fine, the first thing you’re going to want to do (after having a nose around, of course!) is update your 3rd party apps. Start off by opening the App store to see if any that you’ve sourced from there have updates waiting for you. After that, start up all the main apps that you normally use and use their ‘Check for Updates’ option (usually in the Apps main menu), or contact the developers through their websites. If you use Parallels 7, you will need to update that before trying to run your virtual machines.
9. Test your Login Items apps
In particular, you’re going to want to test out the apps that you want to put back in your Login Items, before you put them back in there. Run each app and play around with the system for a couple of hours before deciding to put it back in your Login Items list. If you notice any weird behaviour with Finder, the Dock or Desktop backgrounds, problems with wifi or graphics, chances are one or more of your 3rd party apps needs updating to work with Mountain Lion. If there is no update yet, stop using that app till one becomes available or find an alternative. In general, it’s always best to keep Login Items down to a bare minimum. Running apps at login is a sure fire way to slow down boot up times.

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. DetectX is shareware and 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 DetectX’s removal procedure, I now recommend using DetectX 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. Currently, there are versions of DetectX available for macOS 10.6.8 (Intel only) thru to 10.12.
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!
