Guide To Install Yosemite on HP Laptops with Clover UEFI

Just reinstalled Yosemite.

Installation went fine. Boots to Yosemite after first installation.

Looking for PBI from Christmas (the last beta update). Ran the one updated today. Rebooted after running PBI, clover loads, but then laptop gets stuck on Apple logo at about 25%. Completely reinstalled yosemite AGAIN with same problem. What happened?

Tried booting yosemite with CLOVER partition on install usb. I get a verbose boot with all the background information running. It says "SuperIODevice: {Fatal} found unsupported chip!

So you can boot via USB before PBI, but can't boot by USB after PBI?

Will not boot at all after running pbi.

Accessing yosemite partition through standard efi partition and it freezes as described above.
Acessing through usb clover partition from Yosemite usb gives verbose boot that freezes.

Can you link the last pbi before you updated today?
Its no longer on your website, and I have so many archived pbi, I don't know
which one it was that last worked.

No. Read the description.

Optional. Read the description

No. It's for AMD model without Intel HD.
 

1. Same problem when using clover.
2. When using usb, I get "bug in process subhelperd (214): over-released legacy external boost assertions."

3. The beta 6 PBI version at least prompted my laptop to download xcode when I can it. The RC version did not.

4. Are there different versions of the Yosemite Installer from the app store depending on where I get it from?
 
Your AppleHDAIDT is not the one included in PBI CE. Why do you install it????????

I installed it because it didn't work with the one that PBI CE installed, so I decided to get creative and I followed that link about patching kexts on the fly.

But after following your and RehabMan's advice I was able to get it working.

I have removed the kext (sudo rm -rf S/L/E/AppleHDAIDT.kext ), and re-run PBI CE ticking the box for the 4x40s kexts. I've done Repair permissions (via Disk Utility). Boot without caches (pressing space in clover). Rebuild cache (Kext Wizard). Reboot 2x. On the second time the sound was working (The volume didn't appear in the menu bar but the sound was working, added the volume to the menu bar in the System Preferences). The buttons in the keyboard that control the volume also work (although I don't need to press the fn key to activate it, I might have to check if that is toggled in the BIOS or what)

I don't really know why it didn't work on the other times I installed via PBI CE (I've formatted the disk and followed the guide several times). But I think it might be RehabMan's trick of "
Repair permissions (via Disk Utility). Boot without caches (pressing space in clover). Rebuild cache (Kext Wizard). Reboot 2x.".

Thank you very much, I think you guys are awesome. Judging by the 4540s booting OSX perfectly is very easy. I bought the 4540s because I needed a working OSX. It had it with Chameleon + Mavericks for some months and now I'm very happy that it is working with Yosemite (I needed to update XCode).

Thank You!
