Why? For maximum security settings on your computer, assuming you did create and set a password, do the following.

Go to System Preferences>Security. Check the boxes for Require Password To Wake This Computer From Sleep or Screen Saver; Disable Automatic Login; and Require Password to Unlock Each Secure System Preference. You may have to click on the Lock and enter your Password to enter your choices.

Then, while still in System Preferences, go to Accounts, and click on Login Options. Make sure that Automatically Log In As is not checked, and for Display Login Window As you will check Name and Password. Again, you may have to click on the Lock and enter your Password to enter your choices. If you did not create and set a Password, while in Accounts, click on Your Account in List, then click on Password tab>Change Password. If you did not ever enter a Password, this was left blank. Now you can enter a Password or change your Password here.

Now open up Keychain Access (Applications>Utilities), and open its preferences. Check the box for Show Status in Menu Bar. Now when you need to secure your computer, click on the Lock Icon in your Menu Bar, the first choice is Lock Screen. Selecting this will Lock your screen and start screen saver. To get back in, click mouse or any key, like Space Bar, computer will ask for your Name and or Password.

Setting a hot corner is another faster way of locking your MAC when you have to walk away for a bit. . .

Do what RJphotovideo recommends above and then go to System Preferences > Mission Control and set your hot corner where ever you want on your screen to start the screen saver [which locks the screen automatically if you choose "Require Password To Wake This Computer From Sleep or Screen Saver"

Hope it helps!

Great work. Worked like charm. Can't find any language to praise. It's the best lock application I found so far. Thanks for giving it Free (as in Freedom).

Since this program claims it simply activates Fast User Switching, why not go to System Prefs-->Accounts-->Login Options and check the box to enable it, which then puts an icon in the menubar and has the option to go to the Login Window?

I'm not knocking the developer, but I didn't see any difference between this app and what I have enabled already.

seems like another 'solution in search of a problem to me'.

why not just set your system preferences to require a password to wake from sleep and then put your comp to sleep when you need to leave it for a few mins? - or, if you've got a laptop, just close the lid and it will go to sleep anyway.

[system preferences > security > require password to wake this computer from sleep or screen saver]

when you return just enter your password and all your open docs and windows are as you left them. no need for third party add-ons

While MacLoc may not be the solution for everyone, it is the perfect solution for me and so I thought I'd share it.

I've used the password features in both OS X's screensaver and wake from sleep, but in my situation I'm finding myself having to enter my password way too often.

MacLoc was born out of the need for something that I had complete control over. Since users with desktop machines can't simply "close the lid", MacLoc does exactly what I want, when I want it to.


even considering your not having a powerbook, i fail to see what's so difficult about 'apple menu > sleep' or [if moving that mouse is too much like hard work] hitting the power button and then 'S' - that you felt the need to create a separate app to do this?

This is a good program. Interface is Good as it is 3D when it switches from your desktop to your log-in page.

My Mac is a laptop, and it plays a huge part in my life. On occasion, I need to leave my Mac for just a moment and don't want anybody messing with it. This app is perfect for those moments. ^_^
