Thanks, in part, to this thread, I just got 10.9.5 to work on my Dell Optiplex 990 (Intel i5-2500, 4G RAM, BIOS A18).

BIOS Setting that worked for me:

System Configuration
SATA Mode: AHCI

Performance
Multicore: ALL
Intel SpeedStep: enabled
C-states: checked
TurboBoast: enabled

Virtualization
Intel Virtualization Technology: enabled
VT for Direct I/O: disabled
Trusted Execution: disabled

I now have MacOS 10.9.5 running on my stable of Dells (Optiplex 755, Optiplex 760 and now Optiplex 990 -- all with GT 640 GPUs (Galaxy and MSI).

I started with my clone copy of Optiplex 760.
Had to used KextEdit to build older version on the following kext (needed to do this on all platforms since 10.9.2):

AppleACPIPlatform.kext
AppleAHCIPort.kext
IOAHCIFamily.kext
IOPCIFamily.kext
NVDAGK100Hal.kext
NVDAResman.kext
(all may not be necessary but haven't put forth the effort to reduce this list)

Added this GPU on the Dell 990: MSI NVIDIA GeForce GT 640 2GB GDDR3 VGA/DVI/HDMI PCI-Express Video Card N640GT-MD2GD3
 
Have you bumped up to El Cap yet? If so, does the user dsdt still apply?

Thanks for the post!
 
Anybody had success with Wake-on-Lan with the onboard network card?
 
I can't get the system to boot using UEFI mode in BIOS, only Legacy. Has anyone had success with UEFI mode?
 
Anyone got Sierra up and working? Did the direct update with clover work?

Got Sierra running and basic things like Ethernet, etc work.
Just have to look into audio and powermanagement later today. will upload some guidelines afterwards. :thumbup:
 
Hi@all,

another update regarding Sierra on Optiplex990:
Since using VGA would not work (couldn't even get to the installer), I used an old Nvidia GT430 card. With the card everything worked like a charm using the official install guidelines with UniBeast and MultiBeast.
For MultiBeast I used the following settings:
  • Legacy Boot mode
  • Fake SMC + Plugins+HWMonitor
  • AppleIntelE1000e
  • Clover
  • iMac 14,2
  • Inject NVIDIA
For Audio I had to download Voodoohda (2.88) manually and install it from the package. The MultiBeast-version did not work. Afterwards I applied headbang666's patch for it to set igain to 0 and avoid any static.
Finally I reenabled Speedstepping in the bios which seems to be working out of the box with at least some levels/multipliers.
Will look into this soon.

Hi!

Could someone who has working Sierra share config.plist from CLOVER.
I have everything working on El Capitan, but can not lunch Sierra-installer with my old config.plist.
Computer got frozen after grey background drown.

Thanks.
