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

[zmugu]

I have encountered this when I tried to install Yosemite from my USB.
View attachment 138232
It said "this is not a supported method of installing the operating system."

I have tried to create a bootable USB 1)using UniBeast 5 and 2)following this website: http://www.macworld.com/article/236...otable-os-x-10-10-yosemite-install-drive.html

Both made me encountered the above error.

Someone online said I must have installed the USB incorrectly; but I followed the steps already.

Anyone knows why??!!!! I need help.

Hi,
First you have to download Yosemite form App Store , and don't try to install, let the Yosemite download in the computer, after download Yosemite use UniBeast to create a USB bootable from this link

You have to select if you want to install on PC or laptop, then click install and ready to install Yosemite.

Hi everyone, I'm trying to update from Mavericks 10.9.5 to the new Yosemite 10.10.3.
I tried as Tonymacx said about deleting the files from the /Extra folder, changing the org.chameleon.Boot.plist file and deleting the extension file but so far nothing is good.

Every time I get the message "Can't find /mach_kernel Press a key to continue..."

What am I missing here I also tried several times booting the USB with different flags such as "npci=0x3000 cpus=1" (which are the flags that atm allow me to boot the Mavericks OS).

Can please someone help me?

Thanks

I had to install the latest Chimera to get my Yosemite installer drive to boot. That fixed the mac_kernel error.

I use mavericks. Make the installation (Stick) on a 16 gb partition on a usb hd. Select the Hd via F12 and choice the HD.

Hi, yes i change in org.chameleon.Boot.plist but not in the same line like you, i make other line.

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

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

Now i change the motherboard with i3 processor and works super and now problems, and with 2 lines in kernel flags, i change now in only one line. I put the motherboard asus p8hg1-m lx3 plus r2.0 , hard disck ssd samsung 250 evo, video card evga gtx 750 sc , works good, i dont install sound because i dont know the realtek for this motherboard.
Thx for everitying man.

I looked this up on Asus' website - to answer your questions, the audio is not Realtek ALC, it is Via VT1708S so your only option is to use Voodoo audio or add an external USB audio device. Your motherboard does support the i7-3770.
