First off, this tip does not work with all menu bar items, only Apple-provided menu bar items (like the clock, WiFi status, iChat, etc.) and select third-party application menu bar addons. This reason behind this how to do with how developers add an item to the menu bar: only items through OS X’s SystemUIServer will work with this tip. 

Back when I first switched to the Mac, I couldn’t for figure out a way to move the items on my Mac’s menu bar around. The only way I could figure a way to do it was to manually enable/disable them in the order I wanted them to be displayed. This tip is a simple solution to that problem.

A simple time saving tip that I’ve found useful is to quit open Applications without switching to them first. I’ve got two time saving ways to accomplish that task, first through Mac OS X’s built in Application switcher (Command + Tab) and secondly the Mac OS X Dock.

The Application switcher built into OS X and accessible through Command + Tab, this allows you to quickly switch between open Applications. By striking Command + Tab once and holding down the Command key you’ll see something like the screenshot above with icons for each running Application on your Mac. Pressing Tab again will cycle forward through the list while Shift + Tab will go backwards. A nifty trick is to hit the Q key while you have an Application highlighted in the Application switcher; you’ll notice that the icon fades out, the Application has just quit.

Using Mac OS X’s Dock is also an easy shortcut for quitting Applications. Right-click an open Application and choose Quit from the menu. If you’ve got an Application that has locked up and is not responding right-clicking the Application’s Dock icon will reveal a Force Quit option (much easier than opening the Force Quit window).

Exposé, the application window switching and hiding feature built into OS X  is something you either love or hate. But this article on Exposé is not about its flaws, but instead a cool hidden feature that easily lets you cycle through the open windows of applications open on your Mac.

How to use it: Start Exposé (All Applications or Application Windows) and while its displaying all your open windows hit Tab. Each time you hit Tab, Exposé will cycle from one open application to another, basically switching which application’s windows it’s displaying. If you’re in All Applications mode this will switch Exposé to Application Windows mode, and each subsequent press of Tab will move you to the next application (Shift + Tab to go backwards). Even if there are no applications open with more than one window, this will still cycle through highlighting one window at a time. Pressing Enter will exit Exposé and bring the the selected window/application to the front (Escape also works). A screen shot of this Exposé feature in action can be seen below as well as two videos at the end of this post.

There is no mention of this feature in System Preferences, it seems like one of those things that you’ve got to find for yourself. By default you can enter the Application Windows mode with F10, but this allows easy access to Application Windows from All Applications as well as another nice way to switch applications from Exposé.

I’ve got two videos of this in action, the first shows this trick with single-window applications only while the second shows multi-windowed applications mixed in with single-window applications.

I’ve noticed most people drag an external disk to the Trash in order to unmount/eject a drive from their Mac. Thats not the only way to safely eject a disk from your system though… I can’t claim this tip saves any time, but its one I use quite often when I’ve got several application windows open, this tip is how to eject a disk through the Finder window (instead of the Desktop and the Trash located on the Dock).

Each ejectable disk has a small eject icon next to it in the left sidebar of Finder, this is highlighted in the image above (click on it to enlarge). A simple click on this eject icon will unmount the disk from your system and allow for removal without data loss (providing it ejected without an error). You’ll know its been ejected from your Mac when the disk disappears.

There are other ways of ejecting a drive from your system, using Disk Utility is one, and another method is by selecting a disk in Finder and using Command + E (while a drive is selected).

While I was writing another post for OS X 411, I mistakenly added the word Cyrsis to Leopard’s built-in spell checker, I wasn’t paying attention, but after looking at the word more carefully (after it was added) I noticed it was misspelled. The proper spelling is Crysis, which I assumed Leopard didn’t know anyway, thats how this started… 

Most applications in Leopard that use the built-in spell checker allow you to add words to the dictionary, but not all of them allow you to remove or “unlearn” the learned words. Pages is a perfect example, it will allow you to add words to the spell checker but not remove them. Below I have an example of where I’ve added “Robetr” to the spell checker.

I’ve found two ways to remove a “learned” word from the Leopard spell checker, the first is to open TextEdit and type the word, right-click the word and select “Unlearn Spelling” from the popup (thats it, you’re done). 

If you used the TextEdit method above this is not needed (just an alternate way of removing learned words for the more curious). The second way I’ve found is to edit a file located at ~/Library/Spelling/en (en is the file name (for English I assume), and the Library folder located in your home folder). Open this file in any text editor (TextEdit even works) and remove the word from the list. Once the file is saved logout and you have just unlearned a word. This would also be a practical way to unlearn all the words known by Leopard. Note: The Spelling directory is only created if you have learned words, on a fresh install of OS X the Spelling directory doesn’t exist. It also seems that this file is not synced with the spell checker live, if you delete a name it will still show up as correct until you logout.

Having the ability to change the text on Mac OS X’s Login window is not an explicit feature of Apple’s operating system, it is however possible. Some of the reasons you may want to add text to your Mac’s login window are: security, lost/found and identification. Adding text to the login window is easy, simply add a key and value to a .plist file and logout. 

First you’ll want to navigate in Finder to the following location: /Library/Preferences/ (the Library folder in your hard drive’s root, not your home folder).

Once there, find and open the file com.apple.loginwindow.plist in a text editor like TextWrangler.

Because this file, com.apple.loginwindow.plist is outside of your home folder and effects all users on your system, you must have administrator access on the computer you wish to modify.

Make a backup copy of your original com.apple.loginwindow.plist incase something goes wrong in any of the following steps.

Click to Enlarge

Insert into com.apple.loginwindow.plist somewhere after the <dict> and before the </dict> the italic text exactly how it is shown here: <key>LoginwindowText</key> Once that has been added, directly below it on a new line enter <string>Your Custom Text Here</string> Replace the Your Custom Text Here (red) with your message. Image: The text you will be adding is highlighted in yellow (the end of the line was omitted).

Save the file and logout to test your new login window text. TextWrangler or any other text editing program will ask for an administrator password when you attempt to save this file.

To remove the text you just added, simply remove the two lines of text you added.
