Since Mavericks came out last year, we have gone over features previously unknown to us regular users. We shared secrets of Terminal Commands, hiding and unhiding icons on the desktop, hiding the Dashboard and Notification Center; in the interest of bringing you more things you can do with Mac OS X that you didn’t think were possible, here are 4 more.
Hide/Unhide System Preferences Icons
You could either password protect your utilities with an app like iLock, or you could just go about it the easy way and make it so that a feature doesn’t appear altogether. You can hide certain icons from within System Preferences. Open “System Preferences”, then, with the System Preferences window active, click on “View” in the menu bar above. Select “Customize” and you will be given a list of checkboxes for icons you want to see here. Unchecking will make the icon invisible in System Preferences, checking will make it reappear.
Hide/Show Username on the Menu Bar
If you use multiple accounts on your system, and if for certain reasons, you do not wish for your username to display on the menu bar above, you can just go to System Preferences > Users & Groups > Login Options > Show fast user switching menu as. You will see a list of other options you can access here, such as full name, first name or just icon. Unchecking it will hide the name altogether.
Align Dock On Corners Of The Screen
By default, you can position your dock to the left or right of the screen, just ctrl + click/right click at the space between Trash and your Dock Icons and select the position you want to keep the dock in.
In order to take it one step further, you can move its default position around through the use of simple commands.
defaults write com.apple.dock pinning -string start; killall Dock
If your Dock is in the default horizontal position, the above command will align to the left, if it is on either vertical position, it will align to the top of the screen.
defaults write com.apple.dock pinning -string end; killall Dock
If your Dock is in the default horizontal position, the above command will align it to the right, if it is on either vertical positions, it will align to the bottom of the screen.
To return to the default alignment, enter this command:
defaults write com.apple.dock pinning -string middle; killall Dock
Show One Application At A Time
Some of us are easily swayed by the power afforded to us by multitasking on a computer; you can listen to songs, browse websites and work, all at the same time. For those of us who are easily distracted, this is a veritable punishment as nothing gets done. That can be changed now. You can enable ‘Single Application Mode’ through the following command. This doesn’t kill any running tasks, only minimizes and sends other apps away. This way, when you switch to another app, the previous app goes away, but is still very much alive.
defaults write com.apple.dock single-app -bool true; killall Dock
And you will have only one app visible at a time. In order to revert to the good old multi tasking view, enter the following and you’re all set to run as many applications as your system can sustain.
defaults write com.apple.dock single-app -bool false; killall Dock
