My Optiplex 990 (with EVGA NVIDIA Gtx650 Ti 1024MB) runs on OS X 10.11 El Capitan. What to do?
http://www.tonymacx86.com/el-capitan-desktop-guides/172672-unibeast-install-os-x-el-capitan-any-supported-intel-based-pc.html (For whom might read this in the future. Post-installation with Multibeast 8.0 was not available at that time)

I did a clean install with bootable (LEGACY) USB. To boot from usb and enter the installation I had to modify one entry in .../EFI/CLOVER/config.plist: Graphics -> Inject -> Intel -> false (changed it also after installation on the HD)

After Installation I could boot El Capitan from the USB Clover and it ran smoothly (except sound), but after the Post-Installation procedure (see link) there were some problems. I tried a lot of things at first that didn't work, so I don't know if I forgot any important thing. But the essential configurations are:

For the "Stepper Error 18": turn off "INTEL Speed Step" in your BIOS

Install NullCPUPowerManagement.kext, delete AppleIntelCPUPowerManagement.kext in S/L/E

If someone has a patched DSDT.aml for BIOS revision A19 (please share!) than those steps might not be needed.

I also changed the default SMBIOS from the default iMac 12,2 to MacPro3,1 ... but I don't know if it made a difference.

Sound works with of VoodooHDA (I use the current version 2.8.8). The "white noise" problem is (permanently) fixed by copying VoodooHDA.kext from S/L/E on your Desktop, Right Click "Show Package Content", edit .../Contents/Info.plist by changing the integer value of the gain under IOKitPersonalities->VoodooHDA->MixerValues->iGain to 0. Save it and install the edited VoodooHDA.kext with something like Easykext Utility

Thanks a lot, enzosdue, for the original post.

I'm super stoked - someone just gave me a working Optiplex 990 and am looking to upgrade it to a Hackintosh :D

I noticed that many who have the Optiplex 990 have added in a Graphics Card, is the Hackintosh not possible with the existing on-board?

Im getting the same error, Any updates on this?


hi guys ,
I've got a dell 990 and so far I tried to do the tutorial below, I installed with usb, and after I used multibeast and chameleon like in tutorial. I haven't checked the kernel because when I checked appeared Can not find mach_kernel. Now, if you don't get into safemode, it gets stuck the Apple logo, and if you go into safemode with -x, shows me that. What should I do?

One more thing, after I installed with usb, appeared the error below, and I solved that like in the link.

Error : Article: boot0 Error: The Official Guide

Ok

My first time with all of this. El Captain up and running on 990, 20gb ram, i5, 250gb SSD, GTX 950.

Having trouble getting sound to work via HDMI.

Cannot get Nvidia web drivers to load. It loads the OX basic driver.

also, does anyone have the drivers for a Netgear WNDA3100 WIRELESS drivers?

thanks for the help

Success!!!!!!

Clover configurator helped tremendously!

its up and running beautifully.

Only one question, using the latest web based graphics from Nvidia and it looks a little strange on the HDMI to HDTV.

Anyone know why?

I can't get the system to boot using UEFI mode in BIOS, only Legacy. Has anyone had success with UEFI mode?

Hi, I am trying to install OS X on my Optiplex 990 but can't boot from USB. I tried different loaders, sticks, configurations, can't understand what is the source of the problem. Any suggestions?
Thanks
