I am successfully running iAtkos 1.4i (Leopard 10.5.4) on a new Asus Mobo self-built box.

Built-in Atheros Gigabit ethernet not working (using RTL8139 PCI).

Built-in Sound working in Stereo-Out only with patched AzaliaAudio.

My biggest problem is the reliability of the system. Sure, it RUNS, and when it RUNS it runs fast!

I haven't had a WinXP program crash in months, maybe I am selective about what I run, but I do run quite a few OLD games (Quake II, Slave Zero, Rayman 2). On my new box (and this isn't a complaint, because I am very happy it actually RUNS AT ALL on the cheapest PC available), the software seems "flaky" or "touchy", just a little bit unreliable, especially when launched for the first time on the machine. In one night of use, I would have clicked on the "IGNORE" button in crash dialogs just a few times too many.

The only software I have discovered that does not work at all is:

iMovie '08 (I believe this is a global problem)
Overflow
Quake 1 (any variant)

I am wanting to test this out with a virgin Vanilla Kernel and System.kext to test stability of software - any hints on where to find these for 10.5.4? My sound is usually distorted badly when using vanilla kexts, but this may be fixed with 10.5.5 vanilla kernel etc. with a working PS/2 keyboard patch.

Anyone else having "usability" or stability issues with OSX86, please post your thoughts below!

(this makes me want to reinstall LINUX!, at least it was stable).

EDIT: I am using Kabylkernel with Netkas SMBIOS from original DVD. I am using MBR with Darwin Bootloader. Would it make ANY sense to use GUID + EFI/Chameleon + vanilla kernel/system.kext in relation to stability? Would it make any non-working software run (like Parallels Desktop 4.0 which refuses to even install?).

PS. I have LOTS of files backed up called "mach_kernel.zip" and System.kext, with no way of checking versions (at least not with the kernels) - maybe I should have renamed these before backing them up eh?

OSX isn't build for gaming even if it's old games

.... what u wrote happen cause of roseta translation layer.
thous games are ppc... so bugs are expected... try find a "patched" versions as universal doom, Doom Legacy wich makes a job of protected mode and uses libraries from orignal game. its also usable for many iDsoft games. Quake2 pathed version is on support page of iDsoft... proofed. im playng that on Pentium Dual Core 2200 nad NewBerryLake mobo from intel using integrated GMA950 accelerated. Hope helps u.

I'm running Quake2 on OSX already - I am getting an OpenGL extension related error for any of the Quake 1 universal binaries (FuhQuake, ProQuake etc.)

I have heard anecdotal evidence that using GUID partitioning, along with a vanilla kernel and system.kext can result in much improved disk performance, and much improved reliability - is there any truth to this?

I might reinstall CrunchBang! Linux, as the newer version (8.10.01) is now released.

I have personally found Tiger to be much more stable and a more mature OS in general, and especially most updates being double the size of Tiger's (Safari and the DVD/CD Sharing update are good examples) doesn't help Leopard either.

I agree that Leo isn't quite there yet. Even just recently they were patching things like printing from Illustrator, pretty mundane stuff. Tiger was all tucked in at the end, so everything worked well. Where I work we recently switched to Leo, and not much changed with CS3 performance on the Mac Pro, but I did notice some anomalies like the menu bar showing the Finder, while you were in Illustrator, and needed to be switched around from app to app to get it working right again. Also we lost our network connection to an old unix box with Leo, and keep one computer on Tiger to work around that. It depends on what software you use, if it's all Apple stuff maybe Leo is a way to keep all that working well, along with Mobile Me, etc. Quickview is nice to have when you're looking thru a bunch of pdfs, psds, etc., but other than that Leo is not much better than Tiger.

I may go back to Tiger then, I have the combo 10.4.12 update I think.
