2. Enable Fast User Switching
If there are multiple user accounts on the same Mac, there is no need of logging out from a user account completely in order to login to another account. Simply activate fast user switching, and you can quickly switch back and forth between multiple accounts from the main menu bar. To enable fast user switching in Mountain Lion:
- Select System Preferences from the Apple menu and select Users and Groups.
- Click the lock icon and then enter the admin name and password.
- Select Login Options.
- Check the box labeled ‘Show fast user switching menu as‘
Note: You may still be required to enter the login passwords.
3. Free up Inactive Memory Using Terminal
You can quickly free up memory, without rebooting the Mac, by using the purge command from the Terminal application.
Open the Terminal Application, either by typing Terminal in the Spotlight or by going to Applications -> Others -> Terminal
Once the Terminal Window is open, simply type purge and press return/enter key. OS X will take a few seconds to free up inactive memory. You can see the amount of memory freed in the Activity Monitor (Applications -> Others -> Activity Monitor).

The icon will simply vanish in a poof of smoke.
