Guide: Update OS X Mavericks to OS X Yosemite Using UniBeast and MultiBeast

[maestrorobertus]

Yes I know that. When installing Lion it was one of the tricks I used. Mavericks however was so easy to install, never had problem to type in any extras. So Yosemite is so much more of fumble. I mean why is not even the installer running?
I tried nearly everything, like choosing different USB post, with or without hard drive, checked Bios settings, used different USB sticks, none did even get me closer. It can't be the hardware, mavericks runs fine on it..
Other people where successful with same hardware.

found the solution here: http://www.tonymacx86.com/yosemite-...king-ga-x79-up4-nvidia-geforce-gtx-760-a.html
Its basically: npci=0x3000 cpus=1 before booting the USB. so 3000 not 2000 or 4000 that made the difference !!!

Forgot to delete this when updating:

And installed Yosemite from UniBeast but when to boot it again from UniBeast I get 1/4 of the way through the bar and I get panic. Thats when I boot with: /System/Library/Kernels/kernel.

If I dont boot with flags I just get missing mach.kernel or is it kernel.mach. Either one I'm missing it and it wont boot please HELP!!!

I managed to boot with -f
i think the

<key>Kernel Flags</key>
    <string>kext-dev-mode=1</string>

Is giving the panic. Anyways not nearly as stable as mavericks.

if u can boot with the -f flag it maybe a kernel cache issue(turn usekernelcahe to no)

Just boot from the BIOS and NOT from Unibeast. Select the USB drive in your BIOS and everything should work fine.

Got me around the mach_kernel error

This is what I did, but I still have the same problem:
I've selected from BIOS to boot from USB as primary, then I get the unibeast menu to choose between USB or my Mac OS HDD, I choose USB, then the booting image appears (the apple with a process bar loading) and when the process bar reach a quarter the monitor turns off and there's no video signal... So, what should I do?

EDIT: Solved! I boot with -v flag and the monitor stays ON

Thank you so much for this update. I installed my version without problems.
Except one thing: I cannot sign into iCloud. Which wouldn't be a problem but it is required in order to install some apps and updates.

I am pretty sure I am entering my password correct. This is my set up:

I guess this is related to the problem with iMessage. Unfortunately this has expanded now to other areas, like AppStore and other iCloud related apps. Any advice would be very appreciated.

Thank you!

Carlos.
