DisplayLink has just released an updated beta OS X driver with Snow Leopard 64-bit support.
Previously, Snow Leopard users had to be careful to stick with a 32-bit kernel to use DisplayLink devices. This driver removes that limitation.
The beta drivers are available from DisplayLink here: http://displaylink.org/forum/showthread.php?t=268
These drivers work on all of Plugable’s laptop docking and graphics adapter products (UD-160-A and UGA-2K-A). Note that this driver is still in beta, and has limitations which are noted below in DisplayLink’s release notes.
DisplayLink Mac OS X Software Release: External Release Note
Version: 1.6b1 (23745)
Date: 18th March 2010
Improvements over the DisplayLink Mac OS X Software 1.5 release
* Snow Leopard (64 Bit) Support
More information on how to use this software can be found in the Mac OS X User Guide found on the DisplayLink website (http://www.displaylink.com/mac)
Supported Operating Systems
The DisplayLink software can be installed on any Intel-based desktop
or laptop Apple Mac computer running client versions of Mac OS X Snow Leopard 10.6.2 (32 and 64 bit versions), Mac OS X Leopard 10.5.8 and Mac OS X Tiger 10.4.11.
Note that at the time of writing these were the latest available versions of Mac OS X tested against.
Supported Mac platforms
This software supports all Intel-based Macs. It does not support Power-PC based Macs.
This is a DisplayLink driver release that supports 2D acceleration on Mac OS X platforms. This software has some limitations:
* No 3D (OpenGL) acceleration – some features of Mac OS X applications that require hardware OpenGL
acceleration, such as Keynote presentations and iPhoto slideshows, will not function properly.
* Colour calibration does not work with DisplayLink enabled displays on Mac OS X versions prior to 10.6.2
Note: Applications that require Quartz OpenGL hardware acceleration support will likely exhibit problems with this version of DisplayLink software. Some problems can be avoided by making sure the DisplayLink display is not set to be the main display (the display with the menu bar) If an application refuses to launch when a DisplayLink display is present, try to disconnect all the DisplayLink displays, then launch it and then reconnect the displays.
