Camtasia 2 reviewed

I’ve been a long time user of TechSmith’s Camtasia screen capture software, primarily for two reasons: ease of use combined with a rich set of editing features. Camtasia for Mac 2 strengthens this product in a number of significant ways although there are still some usability issues that need addressing, as well as room for further improvements in the feature set. In this review, I’ll walk you through what Camtasia has to offer as well as indicate the kind of uses where it excels as an aid to the technical communicator. Read the review…

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.

MacKeeper on Mavericks

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:

12/05/2015 17:48:00.946[1]: (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’:

/Library/Application Support/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






~/Documents/MacKeeper Backups





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 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 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!

OS X Lion 10.7 — the jury’s verdict

It’s been over 10 days since the jury went out to weigh up the evidence for and against Mac’s new operating system, 10.7 (OS X Lion). With Apple announcing a million downloads in the first 24 hours, there’s been no shortage of heated debate across the blogosphere and discussion boards (this thread runs to 60 pages and counting! Also see this witty and perceptive post about one user’s frustrations with the upgrade).

So it appears that some love it, others hate it, many are merely sanguine about the whole experience. A number of people are reporting trying it and reverting back to Snow Leopard with brow-mopping relief. My guess, though, is that the vast majority of Snow Leopard users are patiently waiting till a few updates have been released and all the early bugs ironed out.

It’s worth remembering the options: even if you buy Lion now to take advantage of the $30 opening price, you don’t have to install it now. You could buy it and leave the installer app in your Apps folder till the updates get released. Nor do you have to install it over the top of your existing installation. You could install Lion on an external disc instead, or move your Snow Leopard to an external disc and have Lion on your internal disc. Either of those options will allow you to play around with it and switch over fully when you’re truly ready. Don’t forget you can check out whether your existing software will work with Lion.

I have to say though, after ten days, 10.7 is starting to grow on me, and I think the external drive with Snow Leopard sitting on it is going to be gathering dust in a cupboard from now on. That’s not to say I’m thrilled with all that Lion has to offer. It’s a mixed bag, so sit back and let me read the court’s judgement in full. 🙂

The Good, …

    Mission Control

— yes, I have unwillingly been converted. The four-finger screen swipe (left/right to change screen, up/down for Spaces and Expose, respectively) is addictive, and now I don’t think I could live without it. The truth is I could never get along with Spaces or Expose in Snow Leopard anyway, but Mission Control really does sort of force itself upon you. I do miss the App Switcher that is no longer available via the trackpad (Cmd-Tab still invokes it). There are free 3rd Party programs that you can get to add it back into the trackpad, but my experience is they are awkward at best.


— this is an app I use a lot and I love what they’ve done to it. Preview’s enhancements are one of the most undersold changes in all the talk about Lion. It’s always been ahead of Adobe Reader to my mind, but it did have shortcomings, particularly with adding and placing comments neatly and readably. The new Preview has tidied that up nicely, with the comment markers placeable with much finer precision and clear, neat lines indicating which comment each belongs to. The full screen feature also looks great and makes reading a pleasure.


— is growing on me. Switch it back to Classic view for a tidier interface, but there’s still lots of nice things about it. The animated display when you double-click to open a message is very neat (note: you won’t see the animation if you’ve got your IMAP account settings set to ‘Don’t keep copies of any messages’ in Mail Preferences | Advanced).

the Bad, …
Well, overall, the worst thing about Lion is that most of the good things are really cosmetic. There’s not a lot of new things you can do with Lion, and what there are, I don’t like much, particularly the triumvirate of data guardians otherwise known as

    Resume, Autosave and Versions

— Apple has gone to extraordinary lengths to ensure every keystroke, every page, every file you ever open is remembered somewhere (and often in multiple somewheres) on your internal drive and your backup drives. It’s worth noting that not all of these are places the average user can either find or remove. This is something that not everyone is thrilled about, and certainly it’s raised a few eyebrows among the security-conscious. If I were a Chinese blogger, I’m not sure I’d want to update to Lion (you think the Chinese don’t buy Macs? Oh,please!). Another thing worth noting about the Evil Trinity is that Apple has also made them extremely difficult to turn off. Resume, despite what you might be reading elsewhere, cannot be turned off by default (or at least no one’s found a way to do it yet).

However, with all these things, it’s not so much that you can’t beat them, but that you have to work around them. Adjusting your workflow to avoid Resume, Autosave and Versions is certainly possible, but something some may rightly begrudge paying $30 to have to do (in which case, that external backup of Snow Leopard I mentioned above is your friend!). I’ve already written about Resume, and I hope to post workarounds for Versions and Autosave in the near future (sign up for the RSS feed).

The only other ‘bad’ thing I have to say about 10.7 is LaunchPad. This is the iPad look-alike-finger-swiping app display (known as ‘springboard’ on the iPad). A complete waste of time: literally, it’ll take you forever to organise it, and even then it’s a very slow way to find anything but your most familiar apps. There have always been much faster and more efficient ways to get to both your most-oft used apps (the Dock) and those you only occasionally fire up (Finder).

…and the Ugly.
It’s not often that Apple do ugly, but its been universally acknowledged that the designs for iCal, Address Book and Photo Booth are a real eyesore. Fortunately, it’s easy to get rid of them with a bit of mucking about.

So should you upgrade or not? Well, why make it a black-and-white decision when you could have the best of both worlds? If you have a spare drive hanging around, whip it out, pay your $30 and take Lion for a test-drive. If it’s not for you right now, just put it away till the updates smooth it out and the time is right regarding compatibility. After all, if you’ve invested heavily in Apple products or have a lot of legacy material, then it’s probably only a matter of time before you give in and let the Lion tame you, too!
