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

[jae-v]

GA-Z87-HD3 Users do not install the third party sata drivers from multibeast. You'll be stuck with register_decmpfs_decompressor 2 CMP_Type7 in an infinite loop.


If multibeast installation after install is extremely slow repair permissions before reboot.

For anyone installing with Z87X-UD4H and GTX 770, and getting the deadbeef panic, I had to remove the GTX 770, 1 stick of ram, and booted installer with "maxmem=4096" to get the installer to boot/complete. Upgraded from 10.9.5

Alright, so I got the USB to boot using F12, etc, and got Yosemite installer to run. But now when I try to boot back into the disk I installed Yosemite on I am getting the "can't find /mach_kernel" error.

What do I do at this point? Sounded like most people were fine if they got the installer to run.

UPDATE: Whoops, nevermind. I had tried booting from USB again after install but was selecting USB again instead of my boot disk. Working now!

Continuing to get stuck at the apple loading screen after install of multibeast items. I got into the OS using boot flags and installed the 10.9.5 rollback, and that didn't help. Any suggestions?

Update: Wiped my boot drive, started all over, now I'm just getting a kernel panic. Yay

The first half it loaded in a few minutes, then it goes little steps for hours and hours..!?

Pls help!

Hi all,I need help: during Unibeast 1st install ... i got to the OS X setup screen but video is totally out of sync ... and I cannot see anything. Everything is flickering!!! Asus P8-Z77-TH MOBO and i7-3770 , no discrete gf card. I tried -x -v-f .. but no luck!

Solved: flag used at Unibeast's boot: -x -f "Graphics Mode"="1920x1080x32"


iMessage not working after completing the update with Cham 4.0 , iCloud services all working, iTunes working. and FaceTime not working.

Followed the guide, installed over Mavericks - Success!!

Hump #1 [PCI Configuration starting... ] stuck
Solution: Remember to check
Drivers -> System -> AppleACPIPlatform Rollback > 10.9.5 AppleACPIPlatform Rollback

Hump # 2 Audio Not working
Solution: Install AL889 from MultiBeast 6.1.0 (NOT THE LATEST MULTIBEAST). Look under Downloads Archive. All Credits to davidhyde18 post.

But got one last problem to solve - slow boot time...

Great! This helped a lot with PCI Configuration...

Dumb question: Is is faster/easier to do a clean install of Yosemite and then just restore form a time machine backup or follow this guide to update? I am currently running 10.9.5 and am having no issues.


Thanks,
