Change the Minimize Effect in Mac OS X via Defaults Command
When you click the yellow minimize button in Mac OS X, the snazzy Genie effect pulls the window into the Dock. Although you can change between the Genie and Scale effect from within the Dock preference pane, there is a third hidden effect that Apple has chosen to keep out of the preference pane. The hidden effect is named ‘Suck’, it’s more attractive than the Scale effect, and speedier than the Genie effect.
We’ll show you how to activate any of these minimize effects from the command line of OS X by using defaults strings, and remind you that you can change between the standard effects through the preference panels too.

By default, the Mac OS X Dock has a semitransparent white background that holsters the Dock’s icons. ClearDock is a nice little utility that allows you to customize the Dock background to be completely transparent, or if you’d prefer, you can select a different semitransparent color. It’s super easy to use, and best of all, it’s completely free. Check out the screenshot below to see the transparent effect in action.
Mac rumor site AppleInsider is reporting that Apple has filed a patent for a finder feature that would allow different sized icons to be within the same window, with the size of the icon being representative of that items importance. This feature would make a lot of sense for many directories that are crowded with loads of folders and files needed for the application to run, but largely useless for the user to see or interact with. Read on for a mock-up illustration of how this feature would appear within Mac OS X. 
Most of us use iTunes to transfer files to and from our iPod, but apparently you can also use the command line. Sasha Ingbram writes in with this tip: “I realize this is a controversial position to take, but I’m not always thrilled with iTunes and how long it takes to get things done. For me, going through the command this is much faster and more efficient rather than launching iTunes and waiting for the store to load and everything else. I found that you can transfer data to your iPod through the terminal though by using the following command:
If you have ever wanted to turn a DMG file into an ISO file, look no further than the handy command line utility called hdiutil, which is bundled in all versions of OS X. This can be helpful for many reasons, but one of the primary reasons to convert a DMG to ISO is for compatibility. Perhaps your Mac doesn’t have a writable media drive, or it’s not up to speed, or the multitude of other reasons you’d want to have or burn an ISO from a PC rather than a DMG on your Mac.
