Running Mac OS X on x86 PC!

[S.MULLA]

a new emulator called PearPC seems to be able to run OS X on x86 machines:

I keep getting a

"HFS+ has no backup volume header. skipping..."

error. Has anyone else had this problem? I created the ISO of 10.3 on a mac and copied them to the pc, but I can't get it to go any further... any help appreciated.

Come on don't get off topic. This isn't about Adobe.

I'm getting "You cannot install Mac OS X on this volume. You cannot start up your computer using this volume."

Any ideas?

Gheeezus, you people, what was wrong with just running Apple's Darwin OS on your x86..... I hear its a LITTLE FASTER ;) :p

It doesn't have Aqua. Duh.

So now that you've all had your fun arguing, let's get back to making it work.

I have the Mandrake 9.1 PPC, Apple Hardware Test, and Mac OS X Panther CDs. I also have a G4 tower next to my PC but I don't know how to do very much with it other than installing Panther... Can someone walk me through making the ISOs of the Panther CDs on the Mac (since it supposedly doesn't work on a PC)? When I set pci_ide0_master_image to a path like "\\.\D:" (cdrom) then, like windows, it will think any of the Mac CDs in there are raw data and it can't boot them. I was also thinking of taking the hard drive out of the Mac, putting it in my PC, and then somehow pointing pearpc to it (not sure how since Windows will think it is uninitialized and therefore not have a drive letter). Anyways, first I would like to try using cd images, so could anyone tell me how to make them on the Mac?

Rip the ISOs with Alcohol 120% on a PC.

300 x 500 = 150GHz

not if you download the experimental verson! it uses a itsc thingy so its only 40 times slower! :p so on my 3GHz pc, that would mean about.... 75mhz

how do I convert .dmg.sit file to .iso?

[hanxuuk]

google....

looks like u need at least a linux

[jack_canada]

no, works on windows

[Jackalo]

how do I convert .dmg.sit file to .iso?

First, unstuff it.

Next, copy the *.dmg file to a Macintosh running OS X and use Disk Util to convert it to a *.cdr.

Finally, copy it back to your Windows machine and rename the extension to *.iso.

There is NO other way to convert DMG files to ISO.

Arg, in the darwin installation it gets the point of asking me which partition to install it onto but there are no partitions so it mucks up!

Anyone know how to partition it?

Guys... this is a .01 release, Daz actually got Panther installed and _temporarily_ working. For a .01 release, that is astonishing. I can't wait to see how this project evolves.

Make sure that you have the primary master enabled (set to 1 instead of 0)

pci_ide0_master_installed = 1
pci_ide0_master_image = "pearpc-3gib.img"

And as for partitioning it...

Think I'll wait til its developed a little further, no point in wasting time over something with so many bugs.

I use Final Cut Pro and DVD Studio Pro for my stuff. Photoshop is sweet on the Mac.

Ever hear of Adobe Premiere Pro? Adobe Encore DVD? AVID DV?

I do professional video editing for a local TV station, all on macs, and I have many problems with editing on OS X/Final Cut Pro. 75% of everything is the same in FCP, Premiere, and Avid. But the other 25% in FCP isn't the better of the three (in most cases..). The dock, the most 'annoyingist' thing of the century, bugs the **** out of me. It's always in your way; even if you autohide it. Those bouncing icons.. gah.

I'd take a PC over an Mac anyday for video production or image editing. This is comming from someone who is paid to edit video for a living; not someone that does this for fun. Trust me, if your in these apps every day, you get past the pretty aqua look real fast.

Edit: Just to clarify, I have a Dual 1.2ghz G4, 2gb of RAM, 4x36.6gb SCSI HDs, 23" HD Studio Display, and a 19" CRT (for the clips window mostly..).

But hell, who am I to bash a mac. A mac is a mac; it gets done what a PC could do. A PC is a PC; it gets done what a Mac could do. Macs have been able to emulate x86 for a long time, it was only a matter of time before x86's would be able to emulate a PPC.

If your a PCer who wants to get his feet dirty on a mac, by all means mess around with this app ;-). But me, I'll wait for 0.6 or even 1.0 before I even seriously clear HD room for another virtual image :blink:

I've been tinkering with the source code, and may have found a way to speed things up. There is a hard limit in the source code to 10MHz in \cpu_generic\ppc_cpu.h

I'll post my findings in a bit.

see, the reason why school computer is slow is cuz there are a lot of poeple using that machine. everyone handles the computer differently. thats why schools replace their computer every so often. my school are now using emac just last year we were using the same one your using.

These computers are used for only a few classes, and thats it. I have been using these machines since they bought them, and they've always been like ****.

I don't have a mac right now, is there any way to do it on windows?

Is it possible to get a 1:1 cpu speed (not with the current stuff.. but I mean.. is it at all possible?).

What would be the best-case-scenario for the Host:Guest CPU speed? (again, not with the current app; but at all)

only true way to get 1:1 speed is to have a PPC processor rider card installed into your system. Apple use to do this with older PowerPC's they had 486DX processor cards installed in their systems so emulation wasnt nesacery. In an emulated environment though, 1:1 is near impossible because of the conversion of instruction on PPC to instruction to x86 takes more then one instruction to do, therefore loss in cycles, so in the end reduction of performance

haha - i can't even find out how to install GCC

[d10p]

GCC is the GNU C Compiler that Linux uses.
