Activate One Window mode for Safari.

If you’re like me, you’re tired of all sorts of Safari windows all over the place, and wish you could keep them all in one browser window! If that’s the case then you’ll love this terminal trick that does just that for Safari, here’s what you do. Browse to terminal ( applications/utilities/terminal.app ) and enter the following command:

defaults write com.apple.Safari TargetedClicksCreateTabs -bool true

You’ll have to restart Safari for it take effect, but now any links that are set to open in a new window will now open in a new tab saving you from having 10 browser windows open all the time.Of course to reverse this setting, you simply enter the same command except change ” true ” to false at the end.

Speed up Mac Mouse tracking via terminal

Here’s a great Mac OS X terminal trick to change your mouse tracking speeds via terminal.If the available settings in the mouse preference panel aren’t good enough for you, You can adjust the rate via terminal using the following command:
defaults write -g com.apple.mouse.scaling *.*

Replace the *’s with a number between 1 and 5 ie:
defaults write -g com.apple.mouse.scaling 5.0
for fast tracking or
defaults write -g com.apple.mouse.scaling 1.0
for slow tracking

Override Finders maximum icon size

If you really want to jazz up your finder and “supersize” your icons, open your terminal and enter the following command:

defaults write com.apple.finder DesktopViewOptions -dict IconSize -integer 128; killall Finder

Replace 128 with the size in pixels you’d like to set as maximum as high as 512, but becareful not to push the limits of your hardware as it can be very taxing on your system so proceed with caution

Add Hover Effect to Stacks

To add a nice hover effect to the icons in the stacks pop up enter the following code into your terminal ( applications/utilities/terminal.app)  

defaults write com.apple.dock mouse-over-hilte-stack -boolean YES killall Dock

To Remove this Stacks hover effect enter the following terminal command:

defaults write com.apple.dock mouse-over-hilte-stack -boolean NO killall Dock

Here’s a preview of the magic at work.It’s also important to note that this only shows when you navigate your stack pop up by keyboard.

Add Spacers to the Leopard Dock

If you find your Leopard dock a little messy, Here’s a tip that’ll allow you to add spacers to the dock to seperate your apps/documents into groups on the dock.If you’d like a space on the left or application side of the dock, Open terminal (~/applications/utlities/terminal.app) and enter the following command:

defaults write com.apple.dock persistent-apps -array-add '{tile-data={}; tile-type="spacer-tile";}'

If you’d like to add one to the right or document side of the dock enter this command:

defaults write com.apple.dock persistent-others -array-add '{tile-data={}; tile-type="spacer-tile";}'

To see your changes you’ll also need to restart the dock by entering the command:

Killall Dock

Afteryou’ve done this once, you can drag the spacers where ever you’d like and even create more by simple entering the same commands into terminal over again.To remove the space, simply click and drag the space out of the dock like you would any other application or document and ” poof ” it’s gone.

Apparently

wordpress was playing a few games on me in this post .. It should be fixed now, Sorry for the confusion folks.

Remove Leopards 3D Dock

If you’re looking for a way to remove the 3d styled dock from leopard, Here’s how you do it
First open terminal and enter this command:

$ defaults write com.apple.dock no-glass -boolean YES

To change it back simply enter :

$ defaults write com.apple.dock no-glass -boolean YES

Then Type:

killall Dock

The dock will then restart with a new 2D style dock similar to that of Tiger, but slightly better looking in my opinion.
If you’re not up for entering terminal commands and would like to achieve the same thing you can also download the DockDoctor widget from innermindmedia and it’ll let you toggle back and forth with 0 effort right from your dashboard.

Modifying Leopards Stacks

I find Leopards new Stacks feature incredibly useful, and fun to watch at the same time! Here are a few tweaks to help you make the most of stacks.

You can add a ” Recent Items” Stack to your dock by entering the following in terminal ( You can find terminal in /applications/utilities )

defaults write com.apple.dock persistent-others -array-add '{ "tile-data" = { "list-type" = 1; }; "tile-type" = "recents-tile"; }'

Once the stack appears you can right click it and select its type, and a few other features. To add a nice hover effect for the icons in a stack when expanded, Enter this line into the terminal

defaults write com.apple.dock mouse-over-hilte-stack -boolean YES

Type the same, with NO at the end to reverse this effect.

If you don’t like stacks and the reduced folder browsing capabilities, you can download Quay, Developed by Rainer Brockerhof, It Allows you to add your drive, or folders to your dock and browse them via a menu just as you would in OS X Tiger.
