Thanks to Macgasm for pointing out that Apple is now giving away free DVD copies of Mac OS X 10.6 Snow Leopard to MobileMe users still running on 10.5 Leopard. This is to aid those users in making the jump to 10.7 Lion (which must still be purchased from the Mac App Store for $29.99) and thus iCloud before MobileMe’s 30 June 2012 shutoff date. Of course, a copy of Snow Leopard won’t help those still using PowerPC-based Macs, which can’t upgrade past Leopard, but if you’ve simply been dragging your feet, this is a nice enticement to make the switch.follow link
Sleep (and Lock) Your Screen
When you are walking away from your computer, it's fairly common practice to start your screen saver and lock your screen. But did you know that there is a built-in keyboard shortcut in Mac OS X to sleep the screen?
Press Control-Shift-Eject and your monitor sleeps without engaging the screen saver.
