THANKS to everyone on this board who has posted their experiences/fixes/guides to getting OSX on the Sandy Bridge platform, I've got myself a very solid 2500k Mac Pro - and I think from what I can see I may be the first running a Displayport output at 2560x1440, working beautifully with full 3d acceleration. Basically the only thing I have yet to figure out at this point is getting Speedstep enabled - incredible!
Hardware:
Asus P8P67 Motherboard (plain vanilla)
i5 2500k @ 4.3Ghz
G.skill Phoenix Pro 60Gb SSD
Edimax EW-7611UTn Wireless N USB Dongle
Dell U2711 Displayport
Radeon 5850 (MSI Twin Frozr II)
External USB HornetTek D-Slim DVD Drive
Installation process:
1. The iBoot Legacy CD many have used here never worked for me regardless of any PCIRoot options used, so I was able to use the Gigabyte Intel boot CD located here: http://www.mediafire.com/?9lq0il8d0vlra2u.
1b. Before booting I disabled the onboard sound and firewire in the BIOS for installation simplicity. I also disabled SpeedStep to keep the processor at a decent speed. (Otherwise the CPU was stuck at < 800Mhz).
2. Used Macbook Air to install Snow Leopard onto SSD using OSInstall.mpkg (/system/installation/packages/OSInstall.mpkg on leopard DVD)
- This step was necessary because my burned DVD kept telling me that "OS X cannot be installed on this computer" - this MAY not have been necessary if I had disabled Speedstep the first time around.
3. Booted from the same Gigabyte boot CD as above and selected the newly available OSX Partition. No need for any startup flags, or PCIRoot flags. You can use a -v if you like to see what's going on during startup.
4. After Booting into OSX, I installed the latest 10.6.6 Combo Update, didn't click restart at the end, and installed BridgeHelper 1.1.0 and MultiBeast 3.1.0. MultiBeast options were only to use the ATI Experimental Bootloader, and to use 64-bit Apple Boot Screen. (Note that later I changed my boot.plist to 32-bit only, but for the sake of clarity this is what I had done at this point.)
5. Restart the computer, this time without need for a Boot CD (the Boot CD shouldn't be necessary from this point on) wait for the black screen.. and after hours of testing.. I find out that I just had to turn the monitor off and back on to get video! Not sure why this happens yet but a small issue. Anyway - glorious 2560x1400 through my displayport with full Quartz Extreme! Unfortunately the mouse was jumpy and the Quartz graphics were slow. On to the next step.
6. Edit /Extra/com.apple.Boot.plist - for me GraphicsEnabler=yes was already there, but I also added in the following Kernel Flags:
The busratio fixes the mouse speed as well as Video playback, and the i386 locks in 32-bit mode to fix stuttering/sluggish graphics. Eventually there may be a way to boot into 64-bit mode and have smooth graphics, but I'm only using 4GB of memory so it's not a huge deal to me.
So my full boot plist is as follows:
7. I then installed the latest drivers from Edimax for the USB Dongle and had full internet.
8. Installed the latest SleepEnabler from http://code.google.com/p/xnu-sleep-enab ... p&can=2&q=. Sleep works fine, the only issue I've noticed is that I lose my USB keyboard on awake.
9. Installed the latest version of VoodooHDA from http://code.google.com/p/voodoohda/down ... p&can=2&q=. Sound seems to be working perfectly save for a bit of random crackling/popping which is apparently the result of some default.
To do:
10. I'm going to flash a broadcom mini pci-e card to an Airport card ala http://x86wifi.blogspot.com/ as soon as I get the hardware, as the USB dongle is running very slowly.
11. I still need to figure out a way to enable SpeedStep, not 100% necessary but it would be nice from an economical/environmental point of view.
