Hi Cakili,
I'm in Europe time zone so forgive the late response.
Okay, so reading your post, I first must say good job! Looks like you pulled it off first time right. Very good.
Regarding the Audio or lack thereof. Is it working at all? I didn't quite catch that... Did you install the correct AUDIO kext via the latest Multibeast for your motherboard? If your audio is working but iTunes isn't then you have a different issue. Did you select the proper " output" in the sound setting? BTW, are you playing music from your HDD or Internet?
Thanks, again!
So, about the audio problem... I downloaded MultiBeast for Yosemite, ran it, selected to install ALC898 and Optional EFI installed Bootloader Support. When I connected to the internet (ethernet) and went to youtube to test the audio, nothing comes out... So I launched iTunes to try something off my hard drive but there comes another problem - iTunes won't play nothing. It loads the song, but won't respond on clicking the play button. I tried to install the ALC1150 drivers from MultiBeast, but still with no success. Maybe I should try the older version of MultiBeast, for Mavericks?
Regarding the WIFI dongle. I don't have any experience with USB types, but most of use have a TP-LINK PCIE card instead which works out of the box. It is natively recognized and supported by Yosemite.
Any TP-LINK PCIE card will work? Cool, I'll find one and stick it in.
Now the more interesting part with your BOOT devices.
The first part concerning having the GUI always come up without having to hit the spacebar, you will need to boot into Yosemite, mount your MAC OS EFI partition via the tool Mount_OS_EFI.app It automatically mounts the EFI partition. You need edit the config plist go to the BOOT section and change the timeout from 0 to 20 seconds for instance, or set it to -1 to have no timeout.
Done this, works great now. Always brings up the GUI, thanks!
Regarding your BOOT ORDER issues, we have similar motherboards so I would assume the bios isn't much different. Make sure you have selected the right drive (MAC DRIVE) with the UEFI description in the BIOS, do not select the other drives (without the UEFI wording). Also I have removed all other drives as bootable drives from the list.
Done this as well. It is the correct UEFI drive with Yosemite on it, and it loads GUI everytime so this is ok now. But how to remove all other drives from the list in Clover GUI? Like I mentioned, it shows me 4 HDD's that are legacy and none of them boots me into Windows, just blank screen.
In BIOS boot options are like this now:
#1 UEFI Yosemite SSD
#2 Disabled
#3 Disabled
In your BIOS, look under BOOT \ CMS Compatibility Support Mode)
What do you have CSM set to in your BIOS ? Ideally this should be set to disabled. And more importantly if you go to BOOT \ Secure Boot Menu\
What is the OS TYPE set to? This must be set to "OTHER OS" and not WINDOWS OS.
Try this first...
Secure Boot is set to Other OS, so that's cool.
Now this part is tricky...
CSM Compatibility Support Mode is Enabled with Boot Device Control set to UEFI only. When I put CSM Compatibility Support Mode to disabled, and restart the PC i get a message saying:
"The VGA card is not supported by UEFI driver.
CSM (Compatibility Support Module) settings have been changed for better compatibility.
For further adjustments, press [F1] to enter BIOS setup.
If no adjustments needed, press [F2] to confirm the current settings and enter OS directly."
I haven't installed any custom drivers, I figured my card is supported since it is GTX 760. Should I do the step 9b from the tutorial?
Another strange thing, nothing big, but just curious if u have the same problem. I can't set the zoom effects on the Dock in Yosemite. It's always static, and if I choose the option to hide and reveal on hover, it's won't show at all.
Also when doing right click on something, or on desktop, I need to hold it down in order to go into dropdown/subsections, otherwise if I do it like in Windows - right click, then just hover the mouse on option you want and left click on it - it will dissapear with no action.
Seems little bugs are everywhere. I am thinking about doing a fresh install again, in case you don't have these issues. Might be I did something wrong in one of the steps that is causing all this.
