But the Finder does much more than just help you locate files and apps. The Finder has a Menubar menu.
The Finder has a Toolbar which you can customize until the cows come home. As if that’s not enough to make the Finder useful, there’s DesktopUtility, which adds a few Finder-like functions to the Menubar. One click gives you access to four functions, three of which you already have. This is a useful app, but it’s a good thing it’s free.
DesktopUtility resides as a gear icon in the Mac’s Menubar. Click it and you get a pop down menu which will Show Desktop, Show Invisible Files, Hide User Library (toggle), and Force Empty Trash.
Preferences are equally simple in DesktopUtility. Have it open up when you login to your Mac. And have it display and toggle three of the functions.
There are times when you want the Desktop to disappear (and, reappear). Use DesktopUtility to toggle visibility of invisible files. In Mountain Lion and Lion Apple has hidden the user library, but DesktopUtility brings it back so you can see it, and use it.
Force Empty Trash also exists in the Mac’s Finder Menu, but it’s including in DesktopUtility at no extra charge. Plus, it increases the number of functions by over 30-percent.
Who needs DesktopUtility? If you need to check on invisible files, there’s no easier way to view them. Ditto for making the user library visible. But that’s it regarding basic functions. As I said, it’s a good thing DesktopUtility is free.
