Run OSX Yosemite on a Dell Optiplex 780
This tutorial will describe the steps to install Yosemite on a Dell Optiplex 780 (this will also works on a 760).
The installation goes to the latest version of 10.10, and when there is a new update i will change the tutorial as soon as possible.
If you find any mistakes or have something to improve then please send me a PM and i will update the tutorial.

I have also included the PDF file of the guide and the zip file to install OSX Yosemite.

A special thanks goes to Brian from Tech Erra for using parts of their tutorial.

I am from The Netherlands so sorry for my bad English.

1. Credits/Sources
Everything OSx86-related is a collaborative effort amongst people who enjoy doing these things, as well as those of us who enjoy tweaking and experimenting with things. Below are a list of sources used to compile this guide:

And all other forum members who have posted in my topic and helping out the community.

2. Requirements
Here are the requirements:

A Dell Optiplex 780 – This is necessary to install OSX Yosemite for this tutorial
A copy of Mac OS X – This can be in the form of an existing hackintosh, a virtual machine within Windows or Linux, or even a regular Mac. If you don’t have any of these things, then find someone who can help you out for a while. I prefer using a hackintosh with OSX Mountain Lion.
Using an already working copy of Mac OS X either in a VM or a native hackintosh install is HIGHLY recommended.
A 8GB USB flash drive (or larger) – We’ll be copying the files to the drive appropriately, so make sure that you have a flash drive with enough storage space (8GB or larger).
A copy Yosemite 10.10 GM – If you don’t have a App Store Account, then create one to download OS X Yosemite.
30-60 minutes of time – Depending on how tech-savvy you are, this may be quick, or it may take a while.
An SSD or HDD to install 10.10 to – For me, I used a 500GB partition to install 10.10 to.
An PCI Express Video Card – For use with QE and CI Highly recommended. I use a Ati Radeon HD5450 1GB but 512MB or 2GB also works.
CLOVER_780.zip – This ZIP file contains everything that you need to get your flash drive and hackintosh properly prepared.

Note: number 7 contains the files for clover, you can copy the entire directory to the EFI Partition:

3. My Specs
My installation was successfully done on an Dell Optiplex 780 Desktop computer with the following specs.
NOTE: A PCI video card is recommended to use the full potential of OSX Yosemite because the on board video card doesn't support QE/CI.

Intel Core 2 Duo E7500 @ 2.93GHz
8GB DDR3 1333Mhz RAM
Western Digital 500GB HDD
ATI RADEON HD5450 1GB
Intel WG82567LM onboard network
Bluetooth USB Cambridge silicon radio (works OOB)
ADI 1984A HDA audio onboard
HP W2207h Monitor 1680×1050 display
Apple Magic Trackpad
Apple Magic Mouse
Apple Wireless Keyboard US

Enter Bios via tapping F2 during boot.
Change SATA Operation to AHCI (Leave the Booting mode on Legacy! UEFI is not support/does not work.)
Click Save and reboot
Press the F12 key to choose boot device, select USB Drive
When Clover boot screen is visible, choose Boot "Mac OS X from Yosemite".
The system will then boot into OS X Installer.
For a new installation of OS X, you MUST erase and format the destination drive according to the following steps before continuing. If you are upgrading from Lion, Mountain Lion or Mavericks and you want to keep your files and apps, skip steps a-j.

When the installer asks you where to install, choose YosemiteHD, or your existing install.
Upon completion, system will restart a 1st time.
Press the F12 key to choose boot device.
When Clover boot screen is visible, Press F4 (this wil dump your dsdt/ssdt, we don't need it for now), choose YosemiteHD.
You’ll eventually get to the setup screens for OS X Yosemite. Go through that process to setup OS X Yosemite.
Choose by "How Do You Connect" for "My Computer Does Not Connect to the Internet" we will fix this later, go further with the setup process.
The setup process will take about 3 minutes.
Done.

9. Video For HD5450

The DSDT in EFI/EFI/Clover/ACPI/Patched is already edited for HD5450 Video.

Video should be 100% functional if you are using an HD5450 Video Card.

Important: Using the included DSDT with a Video Card other than an HD5450 may cause system conflicts. Pressing F4 at the Clover Boot Menu

will temporarily dump the DSDT. If needed, remove the DSDT from EFI /EFI /Clover /ACPI/Patched.

10. AppleHDA Sound and HDMI Sound For HD5450

There are Two Methods: Clover Injection-Method, and Non-Injection Method.

Clover injection method will not require reinstallation of the AppleHDA.kext after a System Update. Non-Injection Method requires kext reinstall after updates.

Each Method Requires a properly edited, matching Clover config.plist. For More Info see the readme in the AppleHDA Sound Folder..

1. Open AppleHDA Sound folder that is inside the Kext Folder in The Opltiplex 760-780 Clover zip.

2, For Injection-Method: Use Kext Utility to install the AppleHDA.Kext from the Injection-Method folder. The Clover config.plist in EFI/EFI/Clover is already set for Injection Method Sound.

Check to be sure that RealtecALC.kext is in EFI/EFI/Clover/Kexts/10.10, it should be already preinstalled.

AppleHDA.kext MUST be installed in S/L/E. Nowhere else.

3. For Non-Injection Method: Install AppleHDASound.kext from the Non-Injection Method Folder, and install Matching Clover Config.plist from the same folder.

4. Sound may not work until you install System Update to 10.10.4.

11. Ethernet:

Install Intel82566MM.kext that is inside Ethernet Folder.

AppleIntelE1000.kext can be used if you have problems with your Ethernet, it works better for some people.

12. iMessage & FaceTime Fix

You will need MLB and Rom numbers from a legit Mac device that is on the mac server.

Run iMessage debug on a iMac, Macbook, etc, and make a copy and paste of the Terminal Output.

1. Open Clover Configurator

2. Mount EFI Partition

3. Import config.plist from EFI/EFI/CLOVER (File, Import Configuration, browse to config.plist and select).

4 In Clover Configurator Click on RT Variables, Enter Rom and MLB values from iMessage output from valid imac device. Click on calculate.

5 Save changes to config.plist

6 Reboot, Sign into iMessage

iMessage and FaceTime should now both be working.

13. Updating To 10.10.5

1. Download the !0.10.5 Combo Update. Download

2. Install Update

3. Computer Will Reboot After Update is Complete

4. For Injection-Method Sound, No Updates to Kexts Should Be Necessary

5. For AppleHDA Sound, (non-injection Method) use Kext Utility to Reinstall AppleHDA.kext. Reboot!

A HUGE Thanks to MacPeet For AppleHDMA Sound Fix! :thumbsup_anim:

Ok,

Answer this :

Where are your kexts AMDRadeonX3000.kext & AMD5000Controller.kext ?

Did you patch them ?

Is there a copy of those kexts in EFI/Clover/kexts/10.10 ?

teeodor · November 27, 2014

Yes,i put in to s/l/e,now i have copied in EFI/Clover/kexts/10.10 with other kext

polyzargone · November 27, 2014

Ok, let's start over :

Remove AMDRadeonX3000.kext & AMD5000Controller.kext from EFI/Clover/Kexts/10.10

Then follow these steps :

(If all of this is already done, you already have patched kexts in S/L/E). If not, proceed as described :

9. Video Fix for HD5450

Copy the Kext files AMD5000Controller.kext and AMDRadeonX3000.kext from system/library/extension to your desktop.
Go to AMD5000Controller.kext and rightclick and choose Show Package Contents and open info.plist with textedit.

BEFORE REBOOT !

Be sure to set Inject ATI to false in config.plist

Do the following :

open a terminal window and type :

sudo touch /System/Library/Extensions

valide with return key

Now you can reboot

teeodor · November 27, 2014

ok,i do it but nothing has changed

polyzargone · November 27, 2014

Are you using a DSDT ?

teeodor · November 27, 2014

I use the clover 780 zip.

There is inside a dsdt in acpi/patched but sure is not exactly with my optiplex 755 config

polyzargone · November 27, 2014

remove it repair permissions of the whole disk then type this in a terminal window :

sudo kextcache -prelinked-kernel

wait till it's done

and reboot again

teeodor · November 27, 2014

without dsdt i have kp about fakesmc dependency.

This is the result of sudo kextcache -prelinked-kernel

polyzargone · November 27, 2014

hummm … AMDRadeonX3000.kext & AMD5000Controller.kext seems to be corrupted in some way. Copy the orginal ones from you install disk and re-do patches as explained above.

Install them in S/L/E with kext Wizard, repair permissions of whole disk and rebuild the cache with sudo kextcache -prelinked-kernel

this "Prelink failed for com.apple.kext.AMD5000Controller; omitting from prelinked kernel." should have disappeared.

then reboot.

teeodor · November 27, 2014

this "Prelink failed for com.apple.kext.AMD5000Controller; omitting from prelinked kernel." has disappeared

now it's perfect,maybe in the million of try that i do,i used a downloaded kext.

now i'm trying to fix audio

The hdmi it's in grey

The front and the rear work good!

Now i have install voodoohda 2.8.4

polyzargone · November 27, 2014

HDMI audio has no control in system preferences and this is normal because you're supposed to control volume level directly with the HDMI device. VoodooHDA 2.8.4 works fine with 760 & 780 and it shouldn't be different with 755. Maybe you can try 2.8.7 pkg.

teeodor · November 27, 2014

ah ok,the hdmi don't work

teeodor · November 28, 2014

After update to 10.10.1 i reinstall the 2 modified kext and the card is recognize as ati hd5000

polyzargone · November 28, 2014

After update to 10.10.1 i reinstall the 2 modified kext and the card is recognize as ati hd5000

Or you can put Jake Lo's DSDT http://www.insanelymac.com/forum/topic/302877-guide-mavericks-1010x-dell-optiplex-780-760/?p=2088990 in EFI/Clover/ACPI/Patched and forget about kexts patching at every update

In that case, you MUST re-install originals AMDRadeonX3000.kext & AMD5000Controller.kext in S/L/E and rebuild the cache.

teeodor · November 28, 2014

i did it but the card still recognize as ati 5000. Work good but is recognize different

polyzargone · November 28, 2014

That's a minor detail

DSDT is best because you don't have to do anything when the OS is updated

teeodor · November 28, 2014

yes,the card work good

Now i have to find a working hdmi audio,i think it's dsdt problem,but i'm not able

morpheousman · November 28, 2014

After update to 10.10.1 i reinstall the 2 modified kext and the card is recognize as ati hd5000

Provided you have a HD5450 video card, that is normal. OS X does not recognize HD5450, so kext edits are done to make OS X think it is a HD5000.

Also, after any Update, normally you must re-edit the 2 video kexts that the update installed, or video resolution will be out again.

Or if you use the modified DSDT, then you must use only unmodified kexts.

yes,the card work good

Now i have to find a working hdmi audio,i think it's dsdt problem,but i'm not able

After you fix the HDMI audio problem, make sure you come back and share it with us.
