Currently, there are three choices for those who wish to create virtual models on the Macintosh platform. All of the software is available at http://www.ldraw.org/article/97

BrickDraw3D OS X and OS 8.6+ developer release Also a promissing start. Unfortunately I do not have much experience with this program, so I cannot comment effectively.

Mac Brick CAD OS X and OS 8.6+ beta release Mac Brick CAD is a very capable viewer and editor. The latest Cocoa (OS X) release contains a "Part" browser. This LDRAW editor is the most Mac like LDRAW editor because the author, Andrew Allan, has written it from the ground up as a Mac application.

LDGLite for Mac OS X (only) A very capable ".ldr" viewer/editor This program is a port of a program that is designed to run on multiple platforms (Mac OS X, Windows, and Linux); thus, it is not very Mac like. None the less, this program is an excellent choice for those of us with less powerfull Macs eventhough it breaks many of the Mac UI guidelines. By the way, I used this editor to make the ".ldr" file for my GP-30.

LDGLite allows Mac OS X users to view and edit LDRAW .dat (or ".ldr") files, and it works very well. To be fair, it takes a little while to get going, but the time spent is well worth it.

Unfortunately, Macintosh stuff is missing from LEGO®'s site. (The Mindstorms software is another issue; I have been assured that Macintosh Mindstorms software is in the works, but I was told it would be ready in 1999. Until Mac Mindstorms is available there is a work around for people who are desperate to build robots; the Dacta Robolab software, available from Pitsco , can be used to program the "computer brick". Dave Baum has a lot of information about using Mindstorms with a Macintosh including a programing language called Not Quite C or NQC.)

Since I am a Macintosh owner and I felt neglected during my visits to the official LEGO® site--"Wall paper" has been available at official LEGO® site since its creation, but not a single PICT for Macintosh Desktop Pictures has ever appeared--I put together a few icons, and a desktop background.

As you can see the desktop background is a bit busy, and it tends to hide icons, but if you want it drag-and-drop it onto your desktop.

		Each of these gifs makes a pretty good icon; just drag-and-drop and copy and paste.
Ahh! There are great LEGO® inspired desktops and awesome Minifig inspired icons at The Icon Factory
This one isn't really Mac stuff it just happens to be a PowerBook that has been bejeweled. I guess you could glue LEGO to any computer that strikes your fancy.
		But to make a removable LEGO PowerBook cover you must have an infamous PB1400...the only PowerBook which is at the same time both maligned and ordered (I'm sorry), that is, adored by its owners. The hard part wasn't ruining the clear "book cover" but oh the brand new blue plates....( a closer look )
