Mac OS X 10.6 simplified the font smoothing (anti-aliasing) for Mac OS X and all apps within it, but for some the change is unwelcome. If you feel like your screen looks different, it probably does, and the change can be very profound on certain LCD displays. Using the Terminal we can adjust the font smoothing to the same precision that we could prior to 10.6, so launch the Terminal and enter the following command:

defaults -currentHost write -globalDomain AppleFontSmoothing -int 2

the 2 on the end is for medium smoothing which used to be called ‘best for flat panel’, 1 is for light smoothing, and 3 is for strong smoothing. After you execute the command you’ll want to reload the Finder and other apps that are open to see the changes in effect, you can reload the Finder by killing it:

killall Finder

Now your font smoothing will be reflected in the settings you chose.

I found this hint on MacWorld, where the author was complaining of the way fonts looked in 10.6 on his Hackintosh Dell Mini 10v, the changes are very profound on smaller screens and the improvement was very nice on my Hackintosh Netbook (an Acer Aspire) as well.

You can change the Mac OS X login screen background picture using a few different methods. We have covered this tip before but it was based around a few Terminal commands that might not be easy to follow for the average Mac user without command line experience. With that in mind, here are ways to change the Mac login wallpaper:

Change the Mac Login Screen Background

This is the easiest way to change the Mac’s login window background picture, you simply copy a new background image file over the old one via the Finder.

* Change the image of the file you want to use as the new login background to ‘DefaultDesktop.jpg’ – note that it must be a JPG file!
* Hit Command+Shift+G to bring up the ‘Go To Folder’ window

* Type or paste in the following directory path: /System/Library/CoreServices/
* Within this directory, locate the file ‘DefaultDesktop.jpg’ and copy it somewhere else on your hard drive, so that you have a backup of the original.
* Now drag the new image file you want to use as the login background (also named DefaultDesktop.jpg) into the /System/Library/CoreServices/ folder
* You will be presented with a dialog box telling you the file cannot be modified without authentication, click on ‘Authenticate’ – you may need to enter your Admin password

* After authentication, the copy should go as intended, and your Mac login background is now changed! Reboot to see the difference:

The above screenshot is dated from our past article, but this method has been tested and works in Mac OS X Snow Leopard 10.6! You can further also customize the Mac login screen, by changing the Mac logo and whatnot.

Mac OS X Server is infinitely better equipped, more stable, and just generally more pleasant than any of Windows offerings (yes I am biased, but it’s true), if you’re needing a server I highly recommend checking out Apple’s offering. Instead of shelling out the $499 for a copy though, you can get a free evaluation copy! If you’re a large corporation, small business, nonprofit organization, government agency, or educational institution, you can get a free and fully functional evaluation copy of Mac OS X Server directly from Apple. I just found out about this and I think it’s a pretty great thing for Apple to do, so if you qualify for a copy, check it out and you will be impressed.

Snow Leopard changed the way the Dock behaves when a Dock item has been clicked on and held down, since 10.6 it launches Expose for that specific application. You may recall how Leopard handled the click-and-hold though, which was to launch the contextual menu (the same one you get when you right-click in 10.6). Using the Terminal and the defaults write command, you can alter this behavior between the 10.5 contextual-menu and 10.6 Expose style click-and-hold Dock behavior. So launch your Terminal:

Show contextual menu rather than Expose when Dock item has been clicked and held (like 10.5)
defaults write com.apple.dock show-expose-menus -bool no; killall Dock

Revert to Expose upon click-and-hold (10.6 default)
defaults write com.apple.dock show-expose-menus -bool yes; killall Dock

I actually like the new Expose click effect (which is slightly different in 10.6.2 than it is in 10.6), so for me this is a matter of “If it ain’t broke, don’t fix it” but to each their own.

When you go to change the file extension in Mac OS X you will get a dialog box notifying you that by changing a file type it may open in another application. Chances are if you are changing the file extension deliberately, you did this intentionally. You can quickly accept this file type extension change by hitting Command+U when the dialogue box pops up.

This appears to be Snow Leopard only, but I do not have access to an older Mac OS X to test.

If you want to change the wallpaper that sits in the background of your Mac’s login screen, from the Finder hit Command+Shift+G to open the ‘Go to Folder’ screen. Type /System/Library/CoreServices/ and click ‘Go’:

Next, find the image file called ‘DefaultDesktop.jpg’ – you should save a copy of this somewhere safe, or rename it to DefaultDesktop-backup.jpg or something of the sort, so that you can revert your changes.

After that file is safely backed up, add the new wallpaper image you want to use as the login background, naming it exactly the same as the previous file: DefaultDesktop.jpg

That’s all there is to it! Reboot and your login wallpaper is now whatever you set it to. This works to change the login background in Mac OS X Snow Leopard 10.6

With Mac OS X Snow Leopard you can input Chinese Characters directly into the trackpad! This is an extremely cool feature but requires a newer Mac with a multitouch trackpad.

Enable Chinese Character Input in Mac OS X

* Launch System Preferences
* Select the Languages and Text pane
* Click the “Input Sources” tab across the top
* Scroll down to either “Chinese – Simplified” or “Chinese – Traditional”
* After enabled, you can show the trackpad handwriting surface in two ways:
* Either Hit Control+Shift+Space to bring up the Handwriting Input Surface (or whatever else you changed it to in prior screen)
* OR you can select the International keyboards menu bar item and select “Show Trackpad Handwriting” to bring up the Chinese Character Input screen

When the trackpad handwriting feature is enabled, the mouse is disabled for scrolling around and the trackpad itself becomes a writing surface allowing you to draw and input Chinese characters directly into it. The strokes are then monitored and you will be offered different character choices depending on what strokes you enter. Very cool!

If you Option-Click the Airport Menu you can get extended information about the wireless network you are connected to (and the ones you’re not as well), including Channel information, MAC address of the access point, signal strength, and the transmission rate. This is Snow Leopard only, if you haven’t upgraded to Snow Leopard yet and your Mac is compatible, it’s highly recommended.

You can adjust your Mac’s sound volume level silently by holding down the Shift key and then pressing the volume up or volume down keys. This is really handy when you’re in a quiet office or library and don’t want the beep sounds blaring as you adjust system volume.

You can easily resize any disk partition in Mac OS X using the included Disk Utility app, located in /Applications/Utilities, you can even resize a mounted volume but that’s not the best idea in the world. Before you go messing around and resizing your partitions, be sure to backup your data in case something goes wrong.

Since Mac OS X Leopard (and obviously Snow Leopard) you can grow or shrink HFS+ (Mac OS X) Partitions on the fly, with the resizing done live regardless of whether the drive is internal or an external drive.
