Pixelmator has been updated to version 3.0 with a new official name: Pixelmator 3.0 FX (though the Mac App Store, the sole place to purchase Pixelmator, doesn’t append the “FX” to the image editing and manipulation app’s name). The new release uses a new image editing engine that should improve performance dramatically, and adds non-destructive Layer Styles (such as shadows, gradients, and outlines), a Liquify Tool for warping images, and support for OS X 10.9 Mavericks (including App Nap, Compressed Memory, and tags). But these new features come at a cost, with Pixelmator 3.0 FX now selling for $29.99, rising from the special half-price “introductory” cost of $14.99 that it has been selling for since October 2012. ($29.99 new, free update, 35.9 MB, release notes)
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.
