In order to perform some of the interface tweaks listed here you’ll need to install Developer Tools. Sounds scary ? Well, it does, but it really isn’t a big deal.
To install Developer Tools you’ll need to:
OS 10.4 – Insert your Tiger DVD and when the window opens double-click XcodeTools folder to open it. Then double-click XcodeTools.mpkg to install it.
OS 10.5 – Insert your Leopard DVD and when the window opens double-click Optional Installs folder, open XcodeTools folder, and finally double-click XcodeTools.mpkg to install it.
Simple as that. Seriously, that’s it !
hope this works
hope this product does not mess with my mac settings
