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)
Smarter Parental Controls
If you've been using the parental controls options in Mac OS X to lock your child out of using a particular computer late at night, but would like to employ a more clever technique to limit Internet access, turn to MAC address filtering on an Apple base station.
To do this, launch AirPort Utility, select your base station, and click Manual Setup. In the Access Control view, choose Time Access to turn on MAC filtering. You'll need to enter the MAC address of the particular computer, which (in 10.5 Leopard and 10.6 Snow Leopard) you can find in the Network System Preferences pane: click AirPort in the adapter list, and click Advanced. The AirPort ID is the MAC address.
