To patch AppleHDA: 1/ Patch binary by bcc9's script 2/ Put Codec config to info.plist 3/ Patch platforms.xml.zlib and layout**.xml.zlib

Find .app Installer Mavericks around Internet and download it, then make a shared Folder with Vmware. Vmware is out of the topic, I can't have much support, please ask in the author's thread.

After creating SMBIOS, click Save As and save to /Extra folder of your Mac drive.

Find .app in internet, or search for other workaround with InstallESD.dmg. Restore InstallESD.dmg alone won't work.

Try removing AppleIntelHD* kexts, many people reported HD4600 on laptop won't work on 10.10

Hang after or before installing? Can you boot to installer? And I forget packages folder, thank you.

What are you installing? Did you do step 3a/3b?

No need for opening a thread, guide now updated for Yosemite.

Do you have some minutes to read Clear Network Settings in my guide?

I will update the guide when both Clover and Yosemite are stable enough. DP1 is not stable and worthy to upgrade.

If you already show 0a16, inject 0a16 will have no effect.

If you're using Windows UEFI with GPT disk, just create new partition and install. Otherwise, reformat your drive.

Go to System Information > Graphics, what is your Device id?

If you want to patch kernel as Bronxteck said, run HVT and select Kexts > CPU Power Management > patch mach_kernel Or Run the following command in terminal: perl -pi -e 's|\x74\x6c(\x48\x83\xc7\x28\x90\x8b\x05..\x5e\x00\x85\x47\xdc)\x74\x54(\x8b\x4f\xd8\x45\x85\xc0\x74\x08\x44\x39\xc1\x44\x89\xc1)\x75\x44(\x0f\x32\x89\xc0\x48\xc1\xe2\x20\x48\x09\xc2\x48\x89\x57\xf8\x48\x8b\x47\xe8\x48\x85\xc0\x74\x06\x48\xf7\xd0\x48\x21\xc2\x48\x0b\x57\xf0\x49\x89\xd1\x49\xc1\xe9\x20\x89\xd0\x8b\x4f\xd8\x4c\x89\xca)(\x0f\x30\x8b\x4f\xd8\x0f\x32\x89\xc0\x48\xc1\xe2\x20\x48\x09\xc2\x48\x89\x17\x48\x83\xc7\x30\xff\xce)\x75\x99(\x5d\xc3)\x90{7}|\x74\x73${1}\x74\x5b${2}\x75\x4b${3}\x66\x81\xf9\xe2\x00\x74\x02${4}\x75\x92${5}|g' "/mach_kernel" then rebuild cache.

Are you using Clover or Chameleon?

I don't own this laptop, it's based on my experience with other laptops to build the guide. I think it's stable, the audio jack may not work, and FHD + touch may not work too.

It may work, but you'd better repatch dsdt.aml on new laptop.

You can enable 2 finger in Syspref > Touchpad. If it's new version of ALPS, it can be not supported fully. Here is the main page of ALPS touchpad driver, and I'm using the latest driver there. https://osxlatitude.com/index.php?/topic/2545-new-touchpad-driver-for-e6520-alps/ There is no further developement recently. I think you should buy a decent mouse instead.

What is your touchpad brand? ALPS, Synaptics, Elan?
