Not sure if this would help anyone but here is my experience from going from Yosemite (Chimera BIOS) to Yosemite (Clover UEFI).

Originally, I had a working Yosemite install with Chimera. Realized that iMessage stopped working and decided to look into a fix and discovered Clover. While I was at if, figured I might as well try the whole UEFI thing while i'm at it. So, followed this guide to the T and tried booting from my USB stick the Yosemite installer (write over the existing system so I didn't loose anything).

Didn't work, couldn't get the machine to boot from USB. Ended up at a grey screen with blue text and boot options that I had no idea about (just knew it wasn't clover). So, tried reinstalling the USB stick and booting again and this time it worked and got black screened. Realized then video was through my mobo vs.my discrete card.

Was able then to install OSX over again on my existing install and rebooted back to my USB stick and back into my desktop where I installed Clover to the HD (again, to the letter). This time, no go. Anytime I tried to boot from hard drive, it would not boot error no media blah blah blah. I could still boot my system from USB though with full network support and audio/etc, so I assumed everything was working right just Clover wasn't booting right. So after days of trying reinstalls and different boot options, I gave up.

So, started doing some more research related directly to the motherboard and see who else has attempted this. Came across a few other guides that had various levels of complexity on getting UEFI booting with Mavericks/Yosemite. Didn't want to bother with that level of complication.

So, I seen the updated guide on here (Tonymac) about Yosemite and Clover install, and noticed a slightly different method of preparation for the USB stick (1 partition, not two) as well as no special BIOS. In fact, it is recommended that Gigabyte boards use BIOS boot over UEFI. So, I had a spare HD with Windows on it and decided to try a clean install on the HD (Still using the BIOS recommended in this guide). Did the same method same USB stick that worked before except this time.. would not boot and would not show up as a bootable device when pressing F12.

So, confused I did the installer again on a different drive and tried again. This time it worked (weird, don't understand why) and was able to install OSX on my spare HD. Rebooted, went through the setup screen and tried to connect to the net... nothing. Didn't know what was going on, worked before, oh well.

Went ahead and put Clover and the kexts on another USB and installed it to the HD and used my working config.plist file. No go, same errors as before no boot media. Tried different methods, nothing. So, tried BIOS install with Clover (something that should have worked no matter what, did before) nothing, same errors. Then, tried from USB... another no go. So, now I have a non-working/booting system, this time with a kernel panic/error I can't find.

Frustrated beyond belief, I take a gamble (i'm not giving up on iMessage at this point, too much invested in Cover/Configurator/research now) and decide to try the standard Gigabyte BIOS (FYI my board is a rev 1.1 board and it's not a beta BIOS). and went with a UEFI install. Did a time machine backup and formatted my drive from scratch

Followed Tonymac's guide this time and booted from USB first time and had OSX Yosemite re-installed. Booted from USB into my new Mac system (could not do a time machine restore on during setup, network drivers didn't work) and installed Clover to HDD with Kexts and the config.plist for injecting nVidia and this time it worked. Booted form HDD via UEFI to my Mac desktop - only thing not working was the onboard sound (solved with Multibeast).

The only thing I can think of that caused all this was the custom BIOS. For some reason, it wasn't holding something in memory between boots and kept crashing the system. Tried to reinstall it a couple of times all with the same result. Wasn't until I went back to the official Gigabyte one that I had success. May be worth trying for anyone still having problems.

Also, if you follow this thread (http://www.tonymacx86.com/general-help/110471-how-fix-imessage.html) iMessage will work great as well. Recommend a newer iMac model and follow the recommendations about generating new UUID's and random 5 digits after the S/N for it all to work right.

hello Ultrazone,

may i ask for some advise/help please.

I have just updated my hack to yosemite using clover and full UEFI boot.
I have created a DSDT (with HDMI sound patch and pjalm patch for our board)
created my clover config (definition as imac 13.2) and so far all is working fine.
What works (sleep, usb after wake up, sound, i massge, hand off)

I am running bios F14 and my graphic card does not have GOP UEFI so during booting up the system i get a black screen.
So i thought it might work to boot with internal graphic HD 4000 and then have my GT6400 kick in, just as you have done it.

So what needs to be done to do so?
Flash bios to mod version 16 as you suggested and just enable the integrated graphic card in BIOS ?
It is probably not that simple!

Could you please assist me on what changes i need to do to boot up with my integrated graphic card.

Thanks.

If you want to stay at F14 BIOS, try enabling CSM and booting UEFI. That's how I'm doing it now. If you need more detailed info on configuring BIOS this way you'll have to wait, but I can do some screenshots.

Good luck!

Thanks for the Info, but the problem with this board and Yosemite is that you will get USB issues if CSM is enabled.
With CSM enabled you will have freezes after sleep when USB device is plugged in.

But as mentioned above with CSM disabled i have black screen during boot.

That's why i would like to use the internal graphic to boot.
If i could solve this by flashing to bios mod11 F16 and just do the right settings in Bios it would be great?
But i think i would need to do more changes to boot with internal graphic ??

Hi Ultrazone-

First, thank you for such a thorough and helpful guide -- I followed it carefully and was able to get Clover working (almost) perfectly with the Z77X-UD5H & Mavericks in UEFI mode. I took your advice on creating the DSDT and included Pjalm's patches for this board and generic discrete graphics. I even got iMessage to work properly(!)

The trouble now is sleep. Sleep will work if you wake it up within about 8 seconds...however once the motherboard lights all go out (including the current state '03'), nothing will wake it up again.

I'm using the TweakTown F16 mod 11 bios, though thinking of trying F14. At this point I'm just shooting in the dark.

Any suggestions for how to troubleshoot at this point?

Many thanks!

Did you try the power button? There's a setting in Clover (called USB Clock ID) which causes a "deep sleep". In this case the computer only wakes up by pressing the power button.

Check it out! Good luck!

I'm on F14, Clover 2999, Yosemite 10.10.1, CSM enabled, patched DSDT with PJalm's patches and UEFI boot. My board is rev 1.0 and I'm not getting any USB issue at all.

My sysdef is Macmini6,2 and I'm booting from HD4000. Please note this way of booting is not "completely UEFI" since CSM is enabled (necessary for booting from HD4000 without UEFI-GOP).

Hope it helps!

Thanks for the info...I checked and that setting is not selected. I did try the power button and you can hear a relay go off and mb lights flicker for a second but it's like it doesn't stay on. The trouble seems to be with waking up entirely.

I tried the sleep/wakeup cycle in Windows 8 and the result is identical, so I'm suspecting a hardware issue at this point. Others have mentioned a PSU swap fixed it. This may become a back-burner issue...

Thanks again.

Thank you for this guide, ultrazone! Everything worked until I patched SSDT and DSDT yesterday afternoon, and now I get stuck halfway through the loading bar at the apple logo. After this, I will get to a grey screen with the spinning beach ball of death, but that's it. I think it is graphics related, I'm using a GTX660ti. If anyone with a deeper understanding can look at my -v screen below, I would be very grateful... Safe boot is not helpful in this situation, so I'm not sure how to proceed. Cheers!

EDIT: Fixed with reinstall. thanks again UZ!

I'm curious as to why people use macmini6,2 over imac 13,2 or vice versa. It said something about better power management, but that's kind of vague. I've used imac13,2 in the past and just curious what benefit I may see using macmini6,2. And for those using imac13,2 why not use macmini6,2?
