Updating from Yosemite - Computer frozen

Hello everyone !

I built my hackintosh 3 years ago using Ozmosis. I upgraded to Yosemite with succes when it was released, but I didn't take the time to upgrade to El Capitan yet.

I tried to flash my BIOS to then upgrade to El Capitan. As I didn't find the 1669m, I flashed my BIOS with the last one : HighSierra_9. I thought that it would work, but not really. Here is my problem :

My computer is blocked at the BIOS screen (not in the BIOS per say, but when I have the choice to go to BIOS Settings, Boot options, Qflash...). I can't chose any option. Everything is frozen. I can't go in the BIOS, I can't go to boot option. Nothing.

I tried :
- removing extra RAM
- CMOS numerous times
- plugging my screen on my motherboard instead of graphic card
- unplugging any not needed USB (printer for example)

Here is my build :
GigaByte Z97-D3H, Intel I7 4790K, Asus GTX 760, 2 X 8 GO Gskill Pc1600 RipjawX, Crucial M550 512Go (demarrage), Seagate 1To /7200 6Gb/s x2, Noctua NH-C12P SE, Alimentation CoolMaster G600W, Carte Wifi broadcom bcm94360cd. Yosemite 10.10.1

I don't know what I can do now. If you have an idea or solution, it would be great.

I already copied all my files, so I even could make a clean install (I would rather not to, but if it's the only solution...).

Thank you !

Thanks for your answer !

Since my original post, I changed a lot of things. I upgraded to Sierra (with the Sierra_F9 Bios I downloaded on this forum) but I have 2 problems now :
1) my CGU doesn't "work" (after the install, I disabled integrated graphics, but screen became black after apple logo). I heard I may have to install some Nvidia drivers, but I don't want to mess it all up, so I prefer to wait for advice (GTX760 on Z97-D3H motherboard).
2) I can't manage to make my sound work : I used to install ALC1150.pkg from Multibeast when I upgraded, and it worked perfectly. Now, in Multibeast Sierra Edition, I only have Clover-ALC1150 which doesn't work. I tried with VoodooHDA but doesn't work either.

Any idea for both these problems ?

Thanks !

You're right, I had a really simple installation : flashed BIOS with Ozmosis Mod and installed Yosemite from my USB Key. And installing the ethernet and sound (ACL1150) kexts. That's it.

I downloaded Clover Configurator (which I never used before), and mounted the EFI. But I don't have Oz in it. Only EFI>Apple. Do I have to create the OZ folder myself or did I do something wrong ?

By the way, you linked me to 1479m but I have the Sierra_F9 mod. Is your link still good for my case ?

Thanks !!

Done

Indeed, I have Efi>Oz on one of my HDD. Why on this drive and not on my boot drive ?
ANyway, i'll follow what you told me on your precedent post and I'll let you know !

EDIT : So, here are the news :
1) I now have the Ozmosis logo when I boot
2) I can chose to boot on my boot drive or Recovery HD
3) My GPU works fine !!! (thanks again)

Do you know how to solve my no sound problem ? With the same Defaults.plist and changing some options ? I went to your link, but I don't understand everything. It's hard when you never digged in all of this...

I would like to be more and more independant about those issues. Any documentation on Ozmosis that help ? I understood it's not the most popular bootloader, so Its kind of difficult to find good documentation.

(I have to leave home, so I can't work on my hack now. I will follow this thread on my cell).

Thank you

That sounds nice ! I'll be able to check it as soon as I'm home. I'll keep you updated

EDIT : I put the dsdt on the Load folder as you suggested, but I can't boot my computer anymore stuck at loading with the Apple logo
EDIT 2 : I didn't find any solution for now. It won't even let me boot on my bootable drive to make a clean Sierra Install. Can't access to anything

Thanks, but unfortunately, I can't access to the shell either.

I only have access to my BIOS or to the same startmenu as shown here :
https://i.ytimg.com/vi/G384uIQhwUY/hqdefault.jpg

It shows 2 drives. One with no name and the second one, Recovery HD (of course, I have tried to boot on both of them)
Clicking on the top right thing that loos like a shell doesn't do anything.

Don't worry ! You're helping me a lot already ! I've never did this, but i'll find à Clover tutorial tomorrow.

EDIT : Just to be sure : Were you talking about a Clover bootloader stick or a Sierra + Clover stick ?

EDIT 2 : So here is what I did :
- installed clover on my stick
- flashed the BIOS to have the "legit" one (and not ozmosis modded bios)
- enabledXHCI and EHCI Handoff
- disabled VT-d
- unplugged my CGU and connected my screen to my motherboard
- on boot, I had the clover start menu. When I try to boot on either my boot drive (with Sierra already on it) or on my bootable Sierra disk I have this message :

Zitat

OsxAptipFixDrv: Error - requested memoru exceeds our allocated relocation block

- So I reinstalled clover but choosing the OsxAptipFix2Driv this time
- I am on my Sierra Desktop now !
- Installed Clover on my computer boot drive
- Reboot the computer (and plugging my GPU again, disabling intern graphics)
- Hackintosh working using clover !! (with a stretched Apple logo though )

Of course, sound is not working. What should I do ? Stay on Clover and try to find a solution for my missing sound or go back to Ozmosis again ? (I deleted the DSDT)
EDIT 3 :
- I tried to restore AppleHDA using Kext Wizard and the restore the cache, but it doesn't work after rebooting. (AppleHDA.kxt still not in S/L/E)

Thanks again

Great, I'll be there waiting

<p>Everything works perfectly ! Thanks again !</p>
