[rethua]

Yosemite install without much issue. but after multibeast i have one major issue.
only part of USB ports works. some ports does not work at all even tho it works during install
anyone having the same issue??
Gigabyte Z87X-OC with EVGA GTX 760

any suggestion and help is greatly appreciated.

Did you ever get this build running on Yosemite? I got a similar build I want to upgrade.

Go to Finder and in the menu select Go->Computer. Those are file folders you can browse.

I have a Z87X-OC with dual boot Mavericks and Windows 7. I got it set up the first time I tried which means I didn't mess around with Multibeast and Chimera too much. I'm concerned if I follow the directions here that I'll render my Windows 7 partition inaccessible. Any thoughts from the community? Is it "safe" to attempt this upgrade on a dual boot?

Thanks for your patience.

Yeah I have this setup too. Did you ever get it to work and did you have any issues with the dual boot? I got a windows 8 partition. That I would like to keep working!

Here's how I got around the "can't find; mach_kernel" error.
I followed the steps in this guide and still got the error. My problem was that there are two ways to boot from your usb:

1. let chimera load, press any key to bring up the device list, and choose usb.
This resulted in the error

2. press F12 before Chimera loads to bring up the boot menu and choose usb or in my case PMAP.
Using the bios boot menu instead of the chimera boot menu allowed me to boot to the installer without any trouble.

Hope this helps someone!

You are my hero! I still had to use npci=0x3000 cpus=1 at chimera, but the F12 and PMAP thing is what had me lost...I was letting it boot to chimera and trying to do it there...which never worked...for hours!!!!!!!!!!!!!!! ugh

Thank you!

You need the nVidia Web dirvers because OS X does not natively support the nVidia Maxwell chip graphics cards, like the GTX 750, yet. Replace your 750 with your old 5450 and following my steps in my GTX 750 Ti installation procedure here. Ignore the BIOS change steps as your motherboard doesn't support on-board graphics.
