With a quick thumbing of Command+Tab, the built-in OS X Application Switcher is a great way to navigate apps for when your hands are just too busy to leave the keyboard.
One annoyance, though, is that no matter what, Finder is always listed in the Application Swticher, which you may not want to constantly have to be navigating against to go from, say, your e-mail and iTunes. Luckily, for advanced users, removing it from the Application Switcher for good is only a terminal command away.
Here’s what you do. First launch Applications > Utilities > Terminal and enter the following:
sudo nano /System/Library/CoreServices/Finder.app/Contents/Info.plist
Once you’ve authenticated your administrator password, a simple text editor will open in the Terminal windows. Add these lines at the top of the document, right underneath the first:
Now hit Control+O and then hit Enter to save the document, and Control+X to exit out of the editor.
Now exit out of Terminal and hit Command+Tab. Voila! No Finder!
