Mac Tips: [ctrl+alt+delete] on a Mac

Do you struggle with knowing how many applications are currently open on your Mac? Do you find that sometimes an application will freeze or is unresponsive? On a Windows computer most of us are familiar with the command [ctrl+alt+delete].  This command allows us to see which applications are not responding and close out of them.  On a Mac computer that process is called "force quit". To bring up the "force quit" menu, press [command+option+esc] then select the unresponsive application from the force quit window that appears, and click force quit.

The Apple Support article here goes into a little bit more detail about force quit if you are interested in making Mac experience more efficient.
