How To Find iChat Sound Files

Ever wanted to use the sounds you hear in iChat for text messages on your iPhone? Maybe make them ringtones? Or use them for some other purpose on your Mac?

Well, the process for finding these .aiff files is fairly simple. Although you can't find them through a normal search in the Finder or Spotlight, you can get to the folder containing these sound files another way.

First, just use Spotlight to find iChat.app.



Once you see the application icon appear in the Finder. Right-click on the app and choose Show Package Contents. Then go to Contents, then Resources. Presto!

On a side note, after you complete this process, for your own convenience, you can now type .aiff in the Finder and tap Search: Resources to list only the sound files in this folder for iChat so that you can select and copy them easily in a group to another folder.

Bring Back Screen Zoom in Lion

If you have upgraded from Snow Leopard to Lion or Mountain Lion, you may have noticed something is missing. The ability to zoom in and out of the screen on the fly using your mouse or two finger gesture on the track pad while holding down Control isn't present right out of the box.


You can bring this feature back by going to System Preferences, Universal Access, and under Zoom select Options. Now check the box that says "Use scroll wheel with modifier keys to zoom". You have the option of assigning a key other than Control which is nice.

I'm not sure why Apple has chosen to unselect screen zooming by default as it is a useful feature to have, but at least it is still available, albeit buried within System Preferences panes.

View Application Windows Easier in Lion

When you are in Mission Control (OS X Lion or later), and you have several windows open in a particular program or several (as I often do), and you want to view more of the windows overlapping each other, if you have access to a trackpad on your laptop or desktop you can do so very easily.

Just move your cursor over the group of windows and use your thumb and three fingers in an outward motion to activate the gesture. You can also reverse this process to bring the windows back. This might not show you everything in the windows, but it can let you have a better look.



If that is not enough, and you want to view your application windows another way, you can go to System Preferences, and go to Desktop & Screen Saver, then choose Hot Corners. From a dropdown menu you can choose Application Windows. Now when you activate this corner with your cursor you will automatically see most if not all of your windows (depending on how many you have open) and not have the issue of your view being obscured by overlap. Alternately, you can choose the option of left clicking the application icon in the Dock and selecting Show All Windows to achieve the same result.

Ways to jump to the bottom of a web page

In case you were wondering, there's a way to move all the way down to the bottom of a web page without having to manually use the scroll bar all the way there. Just holding Command + Down Key will do the trick, also Command + Up Key will do just the reverse. Additionally, just tapping the Space bar will slightly scroll down the page if you do not wish to go all the way to the top or bottom.

Interestingly enough, if you are using the track pad you have the option of using a three finger upward or downward gesture to go all the way to the top or bottom, but this will only work in Firefox, Chrome, or Opera browsers. For some unknown reason Safari is missing this helpful feature.

Customize the Mission Control Wallpaper in Lion

You have probably noticed when you activate Mission Control, in Mac OS X Lion, that there is a second background image behind the wallpaper you may have already chosen for the desktop. The Linen tiled picture is selected by default for the operating system, but you can change this to a custom image if you desire to give it your own unique look and feel.



Setting Up Your Image

Lion's processing will not recognize a file that does not have the proper extension for the file of the picture you will be using. So, in order for this to work, you will need to either make a new picture in an application of your choosing, or you can simply copy and paste your ready image to an app and export the file with the PNG format. To simplify this process, just follow these steps:

Open the file you want to use as the new Wallpaper (we are using Preview for these directions):

• Go to File, and select Export

• Next, choose the format PNG, and save as "defaultdesktop.png"

If you want to optimize the look of the wallpaper before exporting, you should see if
the resolution of your display matches that of the file you will be using. If the file is too long or too wide you could run into problems with how it displays. The default Linen image is 256 x 256 pixels small square that is used as a tiled pattern. You can check the resolution of your monitor by simply launching System Preferences and going to Displays.



Replace the Mission Control Background Picture



Buried within the system files, this little file is hidden waiting for you to change it. You cannot find this particular file by using Spotlight or the Finder search. Instead, follow these steps to get to it:

• Choose Go from the Finder menu (or hit Command + Shift + G) and type in this location:
/System/Library/CoreServices/Dock.app/Contents/Resources/

• Look through the folders and files until you see "defaultdesktop.png" (you can make a copy of this if you want to revert back to this easily at a later time).

• Select your file you named "defaultdesktop.png" and move it to this Resources folder. You can do this the easiest way by dragging the file over the open Finder window. A window will pop up asking which option you would like to use. Choose Replace. You may have to enter your User Password to Authenticate this process.



• Next, launch Terminal from Spotlight and type the following command:
killall Dock



Now, whenever you use Mission Control by using the assigned F3 key or the three finger upward swipe or by simply using the icon on the dock, you will see your chosen beautiful custom picture appear before your eyes.

If you want to use an existing OS X Lion desktop image as a new Mission Control background, just as we have here in our example, you can find these desktop files by selecting "Go" from the Finder menu, and click "Go to Folder", then type "/Library/Desktop Pictures/". Once here, you can choose a file to copy. Select it, and go to the Finder menu and under Edit, hit Copy. Next, paste to the Desktop or wherever you want to paste. Then open the file in Preview, from there, follow the same process to export the file in the PNG format. After this has been accomplished, go once again to the Resources folder and drag the file over as shown in the preview steps above. Enter your password to Authenticate if needed. And Presto!

If you would like to go back to the default setting, you can just replace the file in the Resources folder with the original backed up Linen image file.

Setting Default Boot Mode

You might be wondering how you can change your boot kernal so that you can use different hardware and/or software or perhaps some other reason.
In OS X Lion, you can choose a default of either the 32-bit or 64-bit kernal, by typing these commands in Terminal:

To select 64-bit mode as default:
sudo systemsetup -setkernelbootarchitecture x86_64

To select 32-bit mode as default:
sudo systemsetup -setkernelbootarchitecture i386

You can also boot up in either of these modes for one startup only without assigning a default mode. You can
do this by holding the 6 and 4 keys during startup for 64-bit mode or you can hold the 3 and 2 keys during startup for 32-bit mode.
