Running Mac OS X on x86 PC!


Question

Because of the fact this thread is <bleep>ing huge, how do I change the memory size? I want it to be 192MB or 200MB or something..

In your config,

##

## Main memory (default 128 MiB)

## must be >= 64 MiB

##

## 0x8000000 (128mb)

## 0x10000000 (256mb)

## 0x20000000 (512mb)

memory_size=0x20000000

In your case, for 192

1024*1024*192 > hex

memory_size=0xC000000

Go into Windows calculator, and switch it to scientific mode. Make sure the 'Dec' radio button is selected, and do:

[MB of RAM you want] * 1024 * 1024

Next, click on the Hex radio button. Take the # that calc has, throw a 0x infront of it, and there is your number ;-).

So, if you want 256MB, do: 256 * 1024 * 1024 and click on Hex. The answer is 10000000, and then add a 0x in front of it, making your config setting: 0x10000000.

PearPC may make or break a normal user's decision on whether they would want to switch to a mac, but it should never change a gamers mind. I run a p4 3ghz with 1gb of ram, and my comp is primarily used to play games, watch DVDs in college, and re-encode TV that i record on my server. Switching to a mac is completely impractical to me. that's why I like being able to use PearPC to atleast try out some of the stuff in OSX and run a mac app, if i find one that i need at some point.

that is the flaw with emulating a PC on a Mac, you can't emulate the PC to play games. but on a PC i can play games and emulate the mac to do other things

Except for a few games all that stuff is easier on a mac.

OS X can even record hdtv signals without extra hardware, all you need a ~500k app. I dont think windows can do that.

And if you can actually get OS X to boot with anything other than 128mb then you're doing better than me :rolleyes:

Okay, here is my first tutorial for PearPC! This guide I just hope it doesn't get lost in the 100000s of posts in this thread! (Maybe I'll add it to the Wiki)

Requirements:

PearPC, Windows, Mac OS X

Tested using:

PearPC 0.2pre (Richard Goodwin's 05.28.04 AMD Optimized Build), Windows XP SP2 RC, Mac OS X 10.3.4

Abstract:

When I started with PearPC, I used the 3gb hard disk image. Quickly the 3gb disk image became filled up, and I required more space. Since I wanted to have a "CD" in PearPC, adding a second hard disk image wasn't possible. This guide will show you how to create a blank image file, add it to your PearPC config, use Mac OS X's disk utility to format it and copy the old disk to the new disk, make the disk bootable, and finally remove your old disk from the config file.

Since I can't figure out how to properly post "tabs", attached is a PDF of the entire step-by-step guide.

It doesn't seem like you have your osx image im the right place. Double check if everything is in the right place. All files should be in the same folder. if they are remove that c:\ from your osx1.iso If your Also check the name of your osx cd 1 iso. Anothe member contacted me and corrected me. my guide had a mistake and he got the same error. is aid to rip the image to osx1.iso. But i ment rip it to osx.iso

Theres your problem right there.

Your ISO should be listed something like this

"C:\pearpc\OSX_CD1.iso"

The image file as well

"C:\pearpc\HD-OS-X-Panther-PREP.img"

unless of course you are working right out of your "C" directory, but in every tutorial I have seen it says make a folder called "PearPC" on your drive.

Yeah I got a slightly different setup. I used the guide from http://s87840517.onlinehome.us/pearpc.html

I even start PearPC with a .bat file like in that guide.

@echo off

cd pearpc-0.1.2-win32-jitc

ppc ppccfg_HD.txt

Not sure if it makes much difference really.

Here is my config file that has working internet and full screen. Just change the IMG and ISO to suit your needs. See if it fixes it. Make a copy of your old one first

That works tw0-fold tho. I really don't see you running Final Cut or DVD Studio Pro on PearPC... Aside from that, what happened to font rendering? The fonts look awful on the desktop / finder...

    • Thanks for liking it! 😊 That's Arch Linux with Gnome.
    • LOL. Can't even quote and edit a comment correctly. Figures you're a Linux user.
    • It won't perform hugely better than the 3080 unless you're VRAM limited in games. Have you tried putting new thermal pads on them 3080 and giving it a good clean to see if you can regain your temps and overclock?
