iTweaX is one of those apps that were born out of the need to make things easier for the common user. This app comes free and is a small download that can make a big difference for you.
Once installed and launched iTweaX will ask for your system password to validate the changes you are making in the system. Of course system changes are somewhat risky, and you need to make sure that what you set in your OS is a change you’re familiar with.
Although it’s great that iTweaX also provides maintenance, cleaning, and restore tools, where it shines most is by its namesake: tweaks!

iTweaX supports the following apps available for all Mac OS X users:
- Finder
- Dock
- Safar 4 and Mail
- QuickTime X
- Spotlight
- Login
- System
- Misc
For Finder, you can set iTweaX to disable icon animations, enhance the finder by enabling the paths to show in the title bar, and you can hide or show elements in the system menu bar.
For the dock, you can set it to be 2D even though it’s in the bottom, use a secret dock minimization animation called the “Suck Effect”, you’ll be able to disable dock animations and lock icons and the dock’s size.
Safari 4 can be tweaked to be in single window mode, and you can limit the history kept by the browser. Mail can be set to force emails to be displayed as plain text, and you can even completely disable data detectors if you want to make it speedier.
iTweaX can make Quicktime X to auto play movies when opened and you can force the controller to show all the time instead of disappearing after sometime.
You can make further changes with this app, even with Spotlight, where you can opt to hide the Spotlight icon completely, and disable some Spotlight functions, like searching in the dictionary and the calculator function.
