Any form of getting OS X to run on unsupported/unauthorised hardware is illegal and unethical.

A PearPC team (Paul Royal, Jimi Malcolm, Matt Wren and Hieu Tran) has managed to install Mac OS X on an Xbox with PearPC.

You will need to modify the Xbox first, install Xebian Linux, then PearPC.

If you've managed to install Linux on your Xbox, it shouldn't be that hard.

Although they do mention "You have purchased a copy of Mac OS X and made an image of it." as requirement, it is well understand that most crackers and hackers who decide to run/try Mac OS X on unauthorised hardware do NOT pay Mac OS X. Even if they bought retail pack of Mac OS X, the license agreement still does NOT Mac OS X to be installed on non-Apple labelled hardware.

Again. Any form of getting OS X to run on unsupported/unauthorised hardware is illegal and unethical. SillyDog701 does not endourse any attempts of installing Mac OS X on unauthorised hardware.

PearPC and OS X sure won't run very fast on a 733MHz Celeron processor with only 64MB of memory. I'm waiting for somebody to hack the 360, which uses a PowerPC-based processor, and get OS X running natively.

Running PearPC and Mac OS X on an original XBox is likely to be so painfully slow, it really isn't worth bothering.
Aside from the illegal/unethical arguments, I really think they're wasting their time and effort with this project.

I know it will be sh#t! Kassie and I modded her Xbox to the max, Greg will tell you, he's seen what we've done to it. It runs Linux, and we've had to put an extra 64MB on the mobo, there's an extra footprint for another chip on all Xbox motherboards, to get it to run even moderately well. The Xbox games don't use the extra RAM though, they're not designed to, but even then Linux runs OK, but not blistering.

I've done a hell of a lot of Xbox modding projects, and depending on the version of Linux you install, plus the quality and speed of the HD you put in, and the dashboard, it will be pretty good, but MacOS X, that's a no-go, not on the old Xbox.

Kassie wants to try and get her new Xbox360 to run MacOSX, which is definitely a do-able thing, with the Xbox having PowerPC processors.

Here's her boxes standard specs:

** Three symmetrical IBM cores running at 3.2GHz each; two hardware threads per core; six hardware threads total

** 500 MHz custom ATI graphics processor; 10MB of embedded DRAM and 48-way parallel floating-point dynamically scheduled shader pipelines; unified shader architecture

** 512MB of GDDR3 RAM memory; 700MHz of DDR; unified memory architecture

** 1 teraflop of overall system floating-point performance

** All games supported in high definition at 16:9, 720p and 1080i, anti-aliasing

** Standard definition and high definition video output supported

The graphics RAM might be a problem, but the GDDR3 main memory, definitely not!

Tidus, I'm not sure that the Graphics RAM would be that much of a problem, My G3 iMac i think has only 16 MB VRAM and its fine with OS 10.3.9 on it at the moment. Perhaps trying the 360 with 10.1 or 10.2 would be a better idea than 10.4 straight away?

The Xbox 360 isn't stuck with just 10mb of embedded memory. It has access to the main 512mb of GDDR3 memory in addition to it's embedded memory. Since the embedded memory has a huge bandwidth link to the rest of the GPU it's used to perform anti-aliasing and other effects with a very small performance hit.

Yeah, I thought that just 10MB sounded a bit small for a new console like the 360.

That was a misunderstanding, my fault! I was being badgered by the missus while i was writing it, and didn't finish. It's still a bit strange how it only has 10MB "dedicated", i would have expected it to have something like 128 or 256, instead of dipping into the main system RAM. That was my point!

I'm really surprised people are still talking about this after two years. For the record, I created that web page to satisfy the requirements for a 2 credit hour "technical communications" class that all undergraduates must complete to graduate from Georgia Tech. Calling it a "project" is probably the first mistake made. ;)
