How to run OSX and NOT on a Mac


Recommended Posts

Get an IBM RS/6000 and install YellowDogLinux...

Then install MacOnLinux...

Q: Does MOL run on non-Apple hardware?

A: It does. MOL runs for instance on the Pegasos board, the Teron board and on AmigaOne hardware. In short, MOL should run on any PowerPC hardware (with the except of 601-based systems). However, the EULA of MacOS prohibits its usage on non-Apple hardware (it is of course perfectly legal to use MOL to boot a second Linux though).

:D

Oh I don't know, some of the big IBM machines may be just a tad quicker than the G5's ;)

OS X won't take advantage of more than two processors so running on a 32-way IBM server isn't much help. MoL does virtualization (the same way VirtualPC on x86 works) no say dynamic recompilation so you'd not see any more performance just because you have more processors.

The Power4 IS the IBM high-end performance chip right now. While the Power4 is designed for reliability, stability, and is incredibly quick - it's not designed to clock as high as the G5 will: in the near future you'll see G5s outpacing it's power4 grandfather. Of course IBM has the power5 under development. (as mentioned: power4 systems cost more than G5s anyway). You'd also be missing altivec on everything other than the G5/G4 - again that isn't going to help performance.

Pilsbury: Don't suppose you could get a few benchmarkts from your friend? ps7bench is popular right now, and if it sees a 3D card maybe you could run Unreal Tournament.

MacOnLinux doesn't do virtualisation at all. All the calls to the processor are native PPC calls. That's why it only runs on PPC....

From their site:

Mac-on-Linux makes it possible to run Mac OS (including OS X) under Linux/ppc. MOL is not an emulator but runs runs the OS directly without any CPU emulation. Moreover, NO ROM IMAGE is required.

It's worth noting as well that the Power4+ machines have a lot more cache than the G4 or G5 do...

That's why I said virtualization and not emulation
Unless my understandy is way off, Virtual PC on x86 doesn't do emulation either: it does virtualization. Programs like soft mac, basilisk, fusion are all 68k emulators.

Virtual PC on Mac OS is equivilant to Fusion on x86, and MoL would be about the same as VirtualPC on x86.

Indeed, that's why I asked for benchmarks :)

Granted Power5 will be out Real Soon Now and by all accounts it's supposed to be disturbingly fast, but in the mean time it'd be interesting to see how well it works on whatever ibm gear we can get a hold of.

Just go out and buy you a Mac. You will be glad you did. :D

I've got a 15" 1GHz PowerBook, a Dual 1.4 GHz G4 Cube, a 2.13GHz G4 (overclocked 1.4GHz upgrade card), a TAM, and have a Dual 2GHz G5 ordered - I think that's enough Macs to do me for now.

But, thanks for the suggestion... :yes:

I disagree - I think maybe you're confused on the terms?

MacOnLinux accesses the processor directly, using native PPC instructions.
That's what makes it virtualization as apposed to emulation.

I can't find anywhere specifically on the MoL site that calls it virtualization (they are very clear it is NOT emulation) however it's been pointed out several times on the MoL mailing list, the first i can find is here:

http://maconlinux.org/lists/mol-general/December00/0098.html

Also, wikipedia has it listed as a virtualization application on it's "list of emulators"

http://www.wikipedia.org/wiki/List_of_emulators

The BEST source of info I can find on the topic is this o'rielly interview with one of the NetBSD developers.

http://www.onlamp.com/lpt/a/3096

NetBSD runs everywhere, but it also runs "everything" (Linux, solaris, and BSD binaries, and now even os x binaries - sans cocoa/carbon/etc) through binary compatibility. He discusses the differences between binary compatibility, virtualization, and emualation so I think this is a pretty good resource.

So, it's nothing like VirtualPC in that respect.

VirtualPC on x86 runs exactly like that - which is what I've been saying all along. You could say VMWare if you'd prefer but it's the same thing.

EDIT: fixed bad quotes

haha you Mac freak!! :happy::

btw, 1.4GHz overclocked to 2.13GHz? that's :woot:: :woot::

    • Lol I heard this last night and I about fell out of my chair. I rebooted again just to be sure I wasn't hearing things.
    • Microsoft accidentally replaced Windows 11 startup sound with one from Vista by Taras Buria The recently released Windows 11 Dev and Beta builds introduced some welcome changes and improvements. However, those preview builds are not flawless and have a pretty long list of known issues. One of those issues, though, is a rather delightful one: Windows 11's default startup jingle has been accidentally replaced with one from 2006. After Windows Insiders discovered that Windows 11 now plays the Windows Vista startup sound and reported it to Microsoft, the company acknowledged it and added it to the list of known bugs in the latest Windows 11 Dev and Beta builds: This week’s flight comes with a delightful blast from the past and will play the Windows Vista boot sound instead of the Windows 11 boot sound. We’re working on a fix. Although Windows Vista is nearly two decades old, it was brought to everyone's attention this week after Apple introduced macOS 26 Tahoe with its controversial "Liquid Glass" redesign, which many consider a rather miserable remix of Windows Aero from Windows Vista and Windows 7. While it is definitely an interesting coincidence, Microsoft did not intentionally replace the startup sound in Windows 11 preview builds. Brandon LeBlanc from the Windows Insider team confirmed in his X that that is a bug after joking about everyone talking about Windows Vista once again in light of Apple's latest announcements: It is worth noting that if you miss the startup sound of Windows Vista, you can still use it in modern Windows versions. All it takes is the original WAV file and a few clicks in the Windows Registry and Sound settings. And for those who want a shot of nostalgia, here is the sound of Windows Vista startup: What startup jingle do you like more: Windows Vista or Windows 11? Share your thoughts in the comments.
    • I refused at $70, $60 was cutting it close for me and I only bought one game at that price, CP2077.
    • Markets are always a follow the leader type of place so to speak. MS didn't raise prices first, but after everyone else did, they will to. Besides, at least they're doing other pro-consumer moves like Play Anywhere. In this case, you can think of it as $80 for 2 copies (console and PC) while Sony and Nintendo would just charge you for both, so $160. Regardless who does it, $80 is too much, even $70 is IMO. Lots of games still come out at $50 and sell well, even if your budget is higher, at $50 the odds are you'll sell more copies and just make it up on volume.
    • How about letting us do an in place upgrade from recovery that would be amazing.
