Keep the spooks and data thieves out of your personal data with this easy-to-use, drag-and-drop 128-bit AES encryption applet. It’s a simple 1-2-3 process:
1. Download EncryptMe, copy to your Applications folder and drag the icon to your Dock.
2. Select the files you want to encrypt and drop them onto EncryptMe’s Dock icon.
3. Choose a password and you’re done!
That’s really all there is to it, but let’s take a moment to go over the details of Step 2 and 3.
How does it all work?
First of all, note that EncryptMe is an Automator “droplet” app. That means you use it by dropping files on it, not by clicking or double-clicking the icon (which will just produce an error message). If you want to know how EncryptMe works (or make your own), just open up Automator.app and take a look a the ‘New Disk Image’ action. EncryptMe sizes the disk image to fit the files you drop on its icon as long as you have enough free space on your drive.
Secondly, take a moment to pause and think about the password options. You can use OS X’s built-in password generator or make one up of your own. However, be careful. This encryption won’t just keep the bad guys out; it’ll keep you out too if you forget the password!
For that reason, you’ll need to think carefully about whether you’re going to tick the ‘Remember password in my Keychain‘ checkbox or not. Doing so gives you far more insurance against losing the password. The flipside is that anyone will be able to access your encrypted files if they gain access to your computer while you’re logged in. Leaving the box unchecked is more secure: the password you set here will have to be supplied every time an attempt to open the files is made even when you’re logged in. The bad news? Forget the password, and you’ll be in the same boat as the spooks and the data thieves, locked out of your data forever. So choose carefully here.
Over the last few years, Apple have made great strides in protecting users from losing their data, be it from system failure, software crashes, accidental deletion, disk corruption or just the plain negligence of forgetting to save before quitting. We now have Time Machine for automatic backups, application savedStates and Resume for crashes, and Autosave and Versions for negligence. As if all that wasn’t enough, iCloud is probably syncing your browser tabs, photos, and pretty much anything else you want straight up to Apple’s servers and pushing it back down the pipe to your other devices as and when needed. All this is a good thing, right?
Well, probably. For most people, most of the time. But not always. The security implications of having your OS (and even Apple) copying everything you type, open or edit on your computer can sometimes be disturbing. What if you need to open a confidential pdf in Preview but are required to make sure (either morally or contractually) that all copies of that document are destroyed after viewing? No one wants to be zeroing their hard-drive every week; and what if you need to edit a Pages or Numbers document but don’t want the changes pushed to the cloud? Turning iCloud on and off is no 2-second job and can have implications for your other workflows and data. Making duplicates to save locally risks having copies stored in the hidden .DocumentRevisions-v100 folder.
Use a secure USB
With USB flash drives now coming in at large GB sizes and relatively low cost, one solution is to load and delete sensitive files via a USB. Wiping a flash drive takes considerably less time than wiping a hard disk and keeps your sensitive data nicely partitioned from everything else, but there are problems. First, there’s always the danger of negligence; in the heat of deadlines or other pressures, we might just forget to wipe that disk; second, there’s the danger of loss or theft; and third, there’s always the possibility of deep recovery by people with the appropriate tools and know-how. Some of those issues can be mitigated by encrypting the drive using Disk Utility.
Set up a RAM disk on OS X
Using an encrypted USB can be a great idea, but it both takes time to create and is not always unobtrusive. If another party should get physical access to your USB, the fact that it’s encrypted also tells interested parties that you might have secrets to hide. A faster and less conspicuous solution could be to use a RAM disk, a portion of your RAM memory that is partitioned and formatted just like any other disk. RAM disks were once common on Macs when peripherals were considerably slower at loading data, but with the speed of modern drives few people bother with them anymore. However, a RAM disk has another advantage apart from being the fastest way to read and write data: its entirely non-persistent. There’s no way of recovering something that was once in RAM once that memory has been flushed.
Making, using and deleting a RAM disk is incredibly simple. Here I’ve created one that’s a half a gigabyte. To create it, you just need a one liner in Terminal. Triple-click the following line and copy and paste it directly into a Terminal window:
diskutil erasevolume HFS+ "ramdisk" `hdiutil attach -nomount ram://1165430`
After you hit ‘return’, you’ll see a new disk icon on your desktop and in the Finder sidebar. You can now use the RAM disk just like any other disk. Use it as the location to download, open or create sensitive files that you know you are going to destroy after use. You can, of course, even create copies of applications and run them from your RAM disk, too.
The RAM disk, while it exists, will behave just like any other disk, so it will have its own .Trashes directory, and its own Versions and Spotlight indexes just as all other disks do. That means you get all the comforts of OSX’s failsafes while the disk is mounted, but as soon as you eject or unmount the disk, all the Versions and Autosaves and Trashes disappear completely and unrecoverably. RAM disks are ideal for reading or editing short pieces of information (such as messages or passwords) that you want to quickly review or store before discarding without a trace.
You can eject the disk either in the usual way from within Finder or the Desktop, or you can use another Terminal line:
hdiutil detach /dev/disk1
And if you want to flush the contents of your entire RAM buffer for good measure, you can also do:
followed by an admin password (if you’re using any version of OS X before 10.9, you can just type ‘purge’ at the command line. No need for sudo or a password).
A word of caution, however. The strength of a RAM disk from a security point of view is simultaneously a danger from almost every other: — the volatility of RAM means you could easily lose everything in your RAM disk if any of the following occur: you eject the disk accidentally, the computer crashes, the power fails or battery runs flat, you log out or restart the computer. Keep these points in mind and only use your RAM disk for short sessions. Never store anything solely on a RAM disk if preserving the data is of importance to you.

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 or FastTasks 2. Both are 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 my app’s removal procedure, I now recommend using them 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. FastTasks 2 requires 10.10.5 or higher.
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!
