Do you remember the day when you first got to play with Apple's new cat? The day when you all went "aaaawww!" after clicking on a stack or using the 3D dock? I certainly do and I have to say that, albeit enjoying most of the changes Apple has introduced in Leopard, like many other people that are using a Mac, I needed to change some of them to the way they were in Tiger or to a better, more unobtrusive look.

For instance, I'm sure that the 3D dock has made lots of fans since day one but there were people out there that did anything they could to change it back to the 2D look they were used to. Another part of the UI that generated lots of controversy is the translucent menu bar, translucency that made the menus difficult to read for some and that simply bothered others just by the looks of it.

What is one to do in such a case? Tweak, of course! And when it comes to tweaking, what else can be more obvious than an interface tweak. In this article, I will present you the most important nine secret Leopard tweaks I have used to make my Mac experience one that I could enjoy even more than if I had used a system with its default settings unchanged.

I call them "secret" because Apple hasn't made them public or included them in an easy to use application that could allow users to customize the OS's interface even more to their liking. I also call them "secret" because they cannot be accessed from any system menu or preference pane and this completely hides them from you or any other less nosey Mac user.

Without anymore talk, let's start the countdown and see how you can easily and quickly force the Finder to display the entire path to a file or directory in the title bar, add movable and removable spacers to the dock, change the login screen background with a single and simple command-line that you can run in your Terminal, customize the look of the menu bar, enable a secret Screen Sharing toolbar, make the good old switch between a 2D and a 3D dock, and disable the Safari option that will auto open the downloads.

1. Force the Finder to display the entire path to a file or directory in the window's title bar
Have you ever found yourself wandering around in the Finder to be able to realize out what the active directory path is? Make the Finder window display it by issuing the following commands from the Terminal:


To turn off this tweak, all you have to do is to type the above commands again and change the YES at the end of the first command with a NO.

2. Add movable and removable spacers to your Mac's dock
The first time I heard about this one, I wondered how spacers could help me with. I'm pretty sure some of you might think exactly as I did but, after trying it, you will find out they are quite handy and that your dock will actually look way better than before. This is especially useful when you have a lot of apps and you want to group them by certain criteria. To enable this tweak, you have to use the following commands:


Your newly created dock spacers can be moved around on your desktop and also be removed by dragging them off the dock or by using the context menu.

3. Change the login screen background
To be able to do such a thing, there is more than one way to go. Some people suggest replacing the DefaultDesktop.jpg file that one can find in the /System/Library/CoreServices/ directory. Although this might work we, as well experienced Mac users, know better than to mess with files that reside in the /System folder and know that a much more proper way to do this job is to change the appropriate preference from the command-line using the following:


where "/Library/Desktop Pictures/Aqua Blue.jpg" is the path to the picture you want to set as your login screen background.

4. Easily customize the look of the menu bar
The one thing that totally annoyed me since day one is the new look of the Leopard menu bar (the translucency effect it had). And after a while, I did manage to find a way to get rid of it and have a completely white and nice looking menu bar as in Tiger. To be able to switch between the different looks the menu bar can have, you must use the following commands (as usual, from a Terminal window):

- Gray menu bar:

- White menu bar:

-Translucent menu bar:

Although this hack has actually been included by Apple in the Desktop & Screensaver Pane under the Desktop tab and you will easily be able to change the menu bar's look with just a click, I still want to mention it here because it is only available as a system preference starting with OS X 10.5.2 and the people that run a OS X 10.5.0 or 10.5.1 will still need it.

5. Enable a secret Screen Sharing toolbar
For the people that use Screen Sharing each and every day, this tweak can deliver quite a boost to the way they manage things while controlling a remote computer. To enable the toolbar with the extra secret buttons, run this command from a Terminal window:


I will let you discover what each new button does and I'm quite sure you are going to be pleasantly surprised.

6. Switch between a 2D and a 3D dock
This is probably the tweak that got the most celebration from the Leopard users who are still divided between the 2D and 3D. The ones that like the dock simple and clean as it was in Tiger, and the ones that will go for the 3D dock look and for the innovative modality to display icons using reflections and all the bling bling that we're used too. To enable the 2D look, you have to run these two commands from the command line:


In case you change your mind, think 2D is not for you after all and you have just made an unfortunate choice, you can easily get the 3D dock back by replacing YES in the first command with NO.

7. Disable the Safari option that will auto open the downloads
Although this is not a Leopard specific tweak, it is included in this article because I find it extremely annoying when Safari starts acting like it has a mind of its own. To enable it, use:


and, in case you get to the conclusion that you like more the old untamed Safari, you just have to run the same command, this time replacing NO with YES.

There are a lot more Leopard related tweaks available out there but I have decided to write only about these because I find them to be the most important and that will have the biggest impact on your Mac experience in the end.
