I've got an issue and need some advice or thoughts on how to proceed. First, I had Mavericks set up and running perfectly on my system with a 3tb HDD and a 120GB Samsung EVO SSD configured as a fusion drive.
I went to upgrade to Yosemite via UniBeast/MultiBeast and kept getting the mach_kernel error that I've seen from several others here. Basically, the first boot from USB was fine and then after running MultiBeast, I couldn't boot either from the USB or the fusion drive. That was after using UniBeast 5.0.0 to create the install USB. So I waited for UniBeast 5.0.1 and started the process over again. This time, first boot from USB worked, but I kept getting the stop sign when the OS tried to load from the fusion drive. I've since learned that this was probably because I enabled TRIM in multibeast, but I didn't know that at the time. I ran across an older thread on here where someone had similar issues and it was related to the logical volume created by the fusion drive. I have a complete time machine backup, so I decided to break up the fusion drive, format/partition both drives, install Yosemite fresh on the SSD, make sure everything was working and then create the fusion drive again and migrate the time machine data over. Although I did get Yosemite running mostly correctly briefly, it was only when I moved the bootloader and /Extra folder to the EFI partition as outlined here: http://www.tonymacx86.com/401-install-bootloader-extra-efi-partition.html . But then I couldn't get the sound working correctly (oddly enough at one point my sound started playing on my apple TV in another room and the computer has no wifi, I checked and the Apple TV was the only output device listed, strange I thought) and, still not knowing about the trim issue, enabled it in MultiBeast and locked myself out from being able to boot again. So once again I had to re-install, it still wouldn't boot correctly, like Chimera wouldn't ever show up.
So, fed up, I started researching the Clover bootloader and decided to give it a go. Which is how I find myself in my current predicament. Although I followed the directions here: http://www.tonymacx86.com/yosemite-desktop-guides/144426-how-install-os-x-yosemite-using-clover.html to a tee, the OS X installer won't boot up from my USB. It gets to the screen with the Apple logo and the progress bar, gets to about 40% and my screen goes dark. I've tried different bootflags, I've waited an hour or so because the indicator light on the USB is flashing, but nothing ever happens. I can't boot to my SSD which has Yosemite on it currently (presumably because I had enabled trim in MultiBeast, although the result is different), the cursor flickers at the top left a couple of times and I am spit back into the UEFI.
So now I cannot boot into any OSX installation, install or boot screen. The only place I can get is to the Clover bootloader, and can't figure out/don't know how to get past that. If anyone has any advice I would really appreciate it. Just thoughts/next steps. I've been banging my head against a wall for days with this and am out of ideas about how to proceed. This is my only OS X computer, so I can't even download the Yosemite installer and re-do my USB with UniBeast and try again with what's more familiar to me. Unless anyone knows a way to download the installer from a windows/linux machine, but as far as I know, you have to access the App store through OS X.
tl;dr - Had trouble with Unibeast/MultiBeast/Chimera, tried Clover and am now stuck with no bootable USB and no backup OS to boot into. Have time machine backup, but can't get past clover boot screen. Help.
