<< Solved >> [Guide] DX58SO Yosemite Successful installation

[edmoncu]

Hi there,

Here are my key PC specs:

• Intel DX58SO (5600 BIOS)
  • Default options with these changes
  • Default SATA AHCI
  • 3rd party SATA - disabled
  • VT options - disabled
  • UEFI - enabled
• Intel i7 930 @ stock
• Intel X-25 40gb SATA SSD (on port 1)
• nVidia GTX 980Ti

Here are the steps:

• Had to have an actual Mac where
  • I downloaded Yosemite from Mac App Store
  • Downloaded Unibeast - for Yosemite
  • Downloaded Multibeast - for Yosemite
  • Setup the USB flashdrive for Yosemite by
    • Using disk manager - erase it to MBR/Mac OS Extended Journaled ; labelling it as USB
    • Run Unibeast and select Legacy option
  • Copy Multibeast onto the USB flashdrive
  • Unmount to eject the USB flash drive
• Going back to the PC to install Yosemite by
  • Insert the USB that we just created and booting to the USB flashdrive (press F10 on the POST) then selecting drive (USB flashdrive) in the Chimera menu type nv_disable=1 to start the Yosemite installation
  • From the Yosemite installation, go to disk utility to format the SSD - important to choose combination of GUID/Mac OS Extended Journaled as the filesystem - label the SSD to MacOSX
  • Start the actual Yosemite installation. Once done it will restart.
  • Boot back to the USB flashdrive BUT selecting the MacOSX drive and use the parameter nv_disable=1. It will start the post Yosemite install on the SSD. Follow the commands until it reaches the desktop.
  • Once on the desktop, run App Store to do a full OS update and install all patches. Allow it to reboot. The build number will change from 14F27 to 14F2511.
  • Boot back to the USB flash drive BUT selecting the MacOSX drive and use the parameter nv_disable=1 to go back to Yosemite desktop.
  • Once back on the desktop, you should see your flashdrive mounted. Open it and run Multibeast.
    • Using the template I had, import it. Install Multibeast. FYI Multibeast setting contains (please un-tick ElliottForceLegacyRTC to prevent any kernel panics)
      • Quick Start > EasyBeast
      • Audio > ALC889
      • Audio > Optional HDAEnabler > Audio ID:1
      • Disk > 3rd Party SATA
      • Disk > Trim Enabler 10.10.3 TRIM Patch
      • EvOreboot
      • FakeSMC
      • NullCPUPowerManagement
      • Network > Intel > AppleIntelE1000e v3.2.4.2
      • Bootloaders > Chimera v4.1.0
      • Boot Options > Basic Boot Options
      • Boot Options > Kext Dev Mode
      • Boot Options > Use KernaleCache
      • System Definitions > iMac 3,1
      • Themes > tonymacx86 Black
    • Unmount to eject the USB flashdrive. Remove the flash drive. Reboot
    • Upon reboot, you should see the SSD is bootable and is showing the Chimera boot screen with the partitions shown, choose MacOSX and use the parameter nv_disable=1 to continue starting up Yosemite. Wait until it reaches the desktop.
    • Download and install the latest nVidia web drivers for 10.10.5 (14F2511). Once done, allow it to reboot
    • Upon reboot on the SSD, select the MacOSX partition and use the parameter nvda_drv=1. You now are able to boot into Yosemite with full resolution.
    • Once on the desktop, you should be able to see the nVidia icon on the upper right menu. Click it to open nVidia Driver Manager. From there
      • Unlock the padlock
      • Choose NVIDIA Web Driver.
      • Lock the padlock
    • All is complete.

Hope this helps people that had similar probs as I initially faced setting up OSX, let alone Yosemite lol.
The reason I posted this is I cannot make Adobe CS 5.5 work under Mojave which i did here.

You may add the following to your /Extra/org.chameleon.Boot.plist

<key>Graphics Mode</key>
<string>1920x1080x32</string>
<key>Quiet Boot</key>
<string>Yes</string>

The next time the HDD boots, it will be quicker and will seem to behave like the real deal
