I was able to update from Mavericks to Yosemite, I did not have any issues.
The steps I followed:
1. setup the BIOS per the TonyMac instructions. see below
2. Back up my OS (just in case I run into any issues).
3. download and created Unibeast per TonyMac instructions
4. Booted to the USB drive and installed Yosemite. I did not partition the hard drive.
5. Stepped through the installation. Used the Unibeast thumb drive to boot into OSX Yosemite, installed all the drivers I needed and rebooted the machine. The machine came right up and I logged in.
Now, the particulars of my machine are as fellows
Gigabyte GA-Z77X-UD5h rev 1 and bios f14
Intel Core i7-3770K Ivybridge
Nvidia GTX 660
16 Gigs of RAM
Bios settings, in my case I have a Win8.1 64bit partition that I run 64 bit VMs on so I did not disable the virtual settings in the bios, I personally have not had any issues with this and I believe from what I've read you only need to do so if you have a non K CPU
Using Multibeast I used the DSDT free option, installed only the drivers I needed, Realtek 898 for audio and AppleIE1000e V3.1.0 for network. I ejected the thumb drive rebooted the machine and it came up. Only issue I had was no sound. To fix that I opened System Preferences >Sound and changed Sound Effects and Output to "Internal Speakers"
Things I did not do. Use the USB 3, I have left those ports empty because in the past I had issues with waking, my keyboard and mouse would not come back. So far its always worked fine with out it. The iMessage, I couldn't tell you if it works or not as I do not have an iPhone so its never been an issue to me.
I hope that helps a bit to answer the question if you can upgrade. Its working pretty nicely for me.
After many tries at installing Yosemite on my Gigabyte z68a board I was about to give up and stick with mavericks, so I decided to update the bios to the uefi bios and restarted and sure enough Yosemite booted up with just easybeast install audio and network works without choosing them from multibeast my system on a core i5 is excellent. so I think if anyone is having problems with install try to update to a uefi bios if its available. So thanks to the community for everything.
