Apple on Monday released an update to its implementation of the
X11 Windowing system, bringing the current version to 0.2. First introduced during Macworld Conference & Expo last month, X11 enables applications based on the X11 windowing environment to run side-by-side with native Mac OS X applications.
The update makes a variety of changes including Support for Gnome, KDE hints; Application windows now cascade instead of piling on top of each if they do not have an explicit placement policy; menu in the Dock now shows a list of X11 windows; Support for Copy & Paste working with other window managers; Support to respect the Mac OS X’s International keyboard mapping; among other changes.
X11 for Mac OS X uses Mac OS X’s own Quartz graphics system, which provides hardware-accelerated 2D and 3D graphics.
X11 requires Mac OS X 10.2 Jaguar and a minimum of 256MB of memory . It’s designed for eMacs, iMacs, iBooks, Power Macs G3s and G4s, and any PowerBook introduced after May 1998.
