Apple releases Mac OS X 10.6.8 Supplemental Update for Snow Leopard

Instead of the usual point release, Apple on Monday released a “Supplemental Update” for Mac OS X Snow Leopard 10.6.8.

The Mac OS X 10.6.8 Supplemental Update is recommended for all users running Mac OS X Snow Leopard 10.6.8 and resolves issues with:

  • Transferring personal data, settings, and compatible applications from a Mac running Mac OS X Snow Leopard to a new Mac running Mac OS X Lion
  • Certain network printers that pause print jobs immediately and fail to complete
  • System audio that stops working when using HDMI or optical audio out

For users who are not running Snow Leopard 10.6.8, Apple has an update combo that will bring your Mac up to date to 10.6.8. The supplemental update is available via the usual software update.

How to setup keyboard shortcuts to easily switch between language input methods in Mac OS X

If you use more than one language for text input, it is necessary to enable keyboard shortcuts in order to switch between the input methods easily and quickly. In Mac OS X, keyboard shortcuts to switch between different language input methods are disable by default. To enable them, open System Preferences and select the “Language & Text” option:


Select the “Input Sources” tab and click on the “Keyboard Shortcuts…” button on the right. This will bring you to the System Preferences menu for keyboard shortcut. Select the item “Keyboard & Text Input” on the left:


You can see that by default the options “Select the previous input source” and “Select next source in input menu” are not enabled. Click on the check boxes to enable these two options:


The system will display yellow triangle icon to warn you that the default shortcut key Command-Space and Option-Command-Space are in used. Command -Space is actually the default used by Spotlight thus we need to change the keys.

To change the keys assigned to the shortcuts, simply double-click on the shortcuts and type in the new shortcut keys. You can use the key Command-[ and Command-] for the shortcuts as shown below:


Once the shortcut keys are defined, you can switch between them by pressing the Command-[ or Command-] keys.

How to change a Mac OS X computer name

When Mac OS X is setup on a new Mac, the default computer name is “John’s MacBook” or “Marry Doe’s iMac” depending on the user name you supplied. It is easy to change the computer name with a unique name to allow users on your network to easily find your Mac.

Start up System Preferences from the Apple menu. Click the “Sharing” icon to open the Sharing preference pane.

System Preferences

Click into the “Computer Name” text field and type in the new name you wish to use.


If you wish to further customize the computer name, click the “Edit…” button and fill in the custom info you with others on your network to see.


Command-Click to move background windows

Clicking on a window under Mac OS X will bring the window and its application into focus. You might used to clicking the background window of an app, bring it on focus, in order to make the app window visible on screen. You can actually move a background window without giving it the focus. Simply Command-Click on the background window’s title bar and drag to move.

This is handy for example if you’re trying to perform a drag and drop of files from Finder into Mail compose window. While composing your email, simply Command-Click to arrange a Finder window until it is visible on the screen. This will save some clicks by keeping the email compose window in focus.

The ever useful four fingers gesture


One of the great differentiator of a MacBook/MacBook Pro notebook compared with its competitors is the trackpad. So much so that Apple released a standalone bluetooth trackpad last year for iMac and MacMini users. The trackpad is multi-touch and is leaps ahead from what you get from other manufacturers.

If you are used to iPhone and iPad, the trackpad’s one or two fingers gestures for zooming and scrolling will be second nature. But many Mac users might not realize the useful four fingers gesture:

  • Instead of Ctrl-Tab to bring up the Switch Applications, just swipe across to left or right with four fingers to bring up the same.
  • Four fingers swipe down will activate Exposé, and you swipe up to exit Exposé mode.
  • Four fingers swipe up will activate the Show Desktop, and you swipe down to exit Show Desktop mode.
