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::

    • I will confirm the Vista hate was ridiculous. They had a point before SP1 and too many didn't use newer components at launch, misleading some to believe it was bad. It really wasn't (after SP1.) The jump from 98/ME to XP didn't get a bad reaction at all from what I remember. 8 was awful. 10 for the most part ran pretty well but people disliked the telemetry and standard MS shenanigans, but 11 is definitely worse in some ways.
    • What I can confirm to not be exaggerations or misinformation is the slowness of the standard right click menus and the Task Manager in Windows 11, even on brand spanking new bare installs.
    • Linux 6.16-rc2: Smaller than usual, but with notable network and bcachefs tweaks by Paul Hill Linus Torvalds, the creator of the Linux kernel, has just released the second release candidate of Linux 6.16. Following the release of Linux 6.15, developers submitted their new features to be merged with Linux 6.16. These release candidates are focused on polishing the kernel before release, following the merging of new features. In his weekly mailing list post, Torvalds noticed that things were pretty quiet this week and that this could be due to developers taking a summer vacation or just taking a break following a large merge window a few weeks ago. This isn’t uncommon at this point in the cycle and Torvalds expects more activity next week. Networking and bcachefs dominate changes The second release candidate, despite being small, still brings some notable changes, namely network drivers, Bluetooth drivers, and bcachefs, a copy-on-write filesystem for Linux. The improvements to network drivers have a direct impact on end users, it means that newer networking hardware works out of the box when you install Linux and existing problematic drivers get fixed. There were also improvements made to the Rust infrastructure and core networking changes. Implementing Rust in the kernel is good for users as it has memory safety built in, leaving hackers less to attack in Linux systems. Rust has received backlash by some opinionated Linux developers who don’t want to learn a new language, but it doesn’t look like it’s going anywhere. Under the hood: specific fixes This week, a diverse set of developers have contributed fixes to the kernel that improve kernel stability, Bluetooth connectivity, file sharing over SMB, and virtualization performance. Some specific changes this week include: Fixes for CPU burning, firmware stats, and use-after-free (UAF) issues with the ath11k and ath12k Wi-Fi drivers. Various fixes for UAF, NULL pointer differences and advertising issues in Bluetooth drivers. Improvements to Server Message Block (SMB) related to directory cache reuse and a fix for performance regression with deferred closes. In KVM (Kernel-based Virtual Machine), there are fixes for SEV-SNP support, memory pre-faulting, and ARM64 selftests. The SMB fixes are notable because it's an important protocol in networked Windows environments. It helps with file sharing, printer sharing, and Active Directory integration. By improving Linux’s support for this protocol, readers using SMB in Linux to talk to Windows machines will have a smoother experience. Ongoing development Linux 6.16 is due to get seven or eight release candidates over the cycle so there are now five or six weeks until the stable version arrives. Even when it is out, most people’s first use of this kernel will be when distributions decide to ship it, as they can be tricky to install manually. Stay tuned each week as we bring you all the new changes which each new release candidate.
    • Just checked my B650 Motherboard again, nothing there as yet, Guess 800 series getting it first, which i can understand as that's newer series, and chipset. I'll check again in a few days or a week depending on how busy i am
