I recently downloaded an application called MacLoc which when activated will switch you out of your user account, instead of logging and closing out your open applications. It’s a one-click process—very fast and easy.
Well, I didn’t realize until today that QuicKeys also has a default macro, titled Lock Screen, that does the same thing. This means that you can use the macro with other shortcuts to switch/lock out your account at a certain time of the day, or after a file is added to a particular folder. You can also activate it remotely using QuicKeys Everywhere if you have the app installed on your iPhone, iPad, or iPod touch.
MacLoc is great, but if you’re QuicKeys users, you can use the macro to perform the same thing.
