Will Diablo 2 work in bootcamp or parallels with the Intel GMA X3100?

You need to use the Diablo II native installer.

So, you download it, run it, and it will ask you to insert your play discs.

But for myself that didn't work. The game was originally written for OS 9 so it seems to have issues I think.

If that native installer doesn't work then you can install windows on boot camp. All you need is a copy of XP SP2 disc or Vista SP1. Then you can run the boot camp utility (That will create disc space for windows, or called partitioning). I would recommend running any games in boot camp than parallels/VMware fusion. In virtualization(What parallels/VMware does) you're running windows on top of OS X, which eats up a lot more hardware resources.

Smerky

Probably. But it will also work just fine under OS X with the latest patch - and Diablo II ships as a hybrid disk - so I do have to wonder why you are trying to run it Windows in the first place...

nope, Apple and Blizzard still have not connected with the latest OS 10.5.6, Diablo II hasn't worked on my macbook since 10.5.2 or 10.5.3....it is very poor planning and development on Apple's part. Blizzard seems to be willing to help fix it but Macbooks still dont have updated 256 colors and other graphic issues. Many people still play this almost 10 year old game everyday.....It's pretty much amazing

That is odd... I have 10.5.6 on my new MacBook and Diablo II runs fine on my machine, so I know it works.

Perhaps you can drag out your Save folder out of your Diablo II folder, nuke Diablo II and start over from scratch with the OS X installer? Let all the patches run to the latest version, of course, and put a copy of your Save folder back where it goes. Like I said, it's working on my machine, so perhaps there is something corrupted in your install...

Hey Wolf, What graphics option on D2 do you use? Open GL or Software and if Open GL, thousands of colors or millions? I'm going to try to reinstall today with and keep my save folder....so i hope all goes well (i've been waiting and trying this with all the versions of Leopard)....fingers crossed

EDIT:
Just tried reinstalling Diablo II on 10.5.6 and I have still have a problem as always....as soon as I click on my battle.net character it crashes....never fails

I'm not sure if this helps but I have the integrated GMA 950 graphics on my macbook

any ideas??
please I want to uninstall boot camp as soon as possible

anybody think of anything? I'm absolutely dying every time I have to restart to use windows..ugh...

there is a beta patch flying around which works.
With this you can play Diablo 2 + exp on any Macbook carrying the X3100.

Bear in mind that this is still in its beta stages and you cannot play online.
