Install With MultiBeast

MultiBeast requires you to know your motherboard. 

1. Navigate to your motherboard manufacturers website, Google search your motherboard model number. Generally the first search result will be the one you want. See Gigabyte Motherboards / ASUS Motherboards.

2. Search for the Specification tab to find out which Ethernet and Audio codec your motherboard has (jot these down).

3. If your motherboard has UEFI BIOS, your motherboard doesn't require a DSDT. (DSDT is required for HDMI Audio). 

3a. If your have a Legacy BIOS you will most probably need a DSDT. See How To Install a DSDT

4. User DSDT/DSDT Free Installation must be selected whether you have a DSDT or DSDT Free installation. This will install everything you need to boot from your hard drive. 

5. Installing Mountain Lion, 

Graphics Cards 

Buyer's Guide require you to navigate in MultiBeast to Customizations/Boot Options/select GraphicsEnabler=No as these are supported natively in OS X.

5a. MultiBeast For Mavericks default is GraphicsEnabler=No and IGPEnabler=Yes(giving the opportunity for both Discrete and Integrated graphics). Recommended selection for IGPEnabler=Yes is Customizations/Boot Options/1080p Display. Note that VGA ports aren't supported by OS X.

Be sure to read the PDF file document included with MultiBeast, this has all the install locations. Which is brilliant if you were to make a mistake. This is also available at

Please know that when using MultiBeast 6.0.0 or later for OS X Mavericks that the default for GraphicsEnabler has changed to GraphicsEnabler=No. If your graphics isn't supported natively then you will have to select under Customizations/Boot Options GraphicsEnabler=Yes

Reminder: NVIDIA GeForce 6xx/7xx Kepler Cards work with GraphicsEnabler=No

Verbose Mode- allowing you to see the loading of the OS instead of the Apple Boot Screen. Same as holding "v" on a Mac at startup.

Safe Mode- loads only basic drivers. Same as holding "x" on a Mac at startup.

-sSingle user mode- allows user to access the command line before booting the OS. Same as holding "s" on a Mac at startup.

This setting may be necessary on motherboards using Fermi and Kepler NVIDIA cards for installation.

Format a 8GB+ USB with GUID partition mapping and name it Install.
Insure the OS X is in your Application folder.
In terminal run the following script.
sudo /Applications/Install\ OS\ X\ --volume /Volumes/Install --applicationpath /Applications/Install\ OS\ X\ --nointeraction
This will take several minutes so be patient, the script will notify you when complete.

Now Install Clover r2696 (or newer) to the Install USB. Clover r2953 or newer Recommended! 
Copy FakeSMC and Network kexts to /EFI/Clover/kexts/10.10  (you’ll have to create the 10.10 folder}
Boot USB to Clover, highlight "Install OS X Yosimite" and hit the spacebar, choose "with injected kext”
and install Yosemite. Re-boot to USB and select your SSD or HD, hit the spacebar and again
choose “with injected kext” to complete the installation.
Install Clover to your boot drive. install your kexts to S/L/E or use Clover to inject kexts from EFI/Clover/kexts/10.10

EDIT: For anyone having a problem with this process:

You might try using the HFSPlus-64.efi (Google it) rather than VBoxHfs-64. Also be certain you're booting from a USB 2.0 port.

EDIT: you might also try the latest Clover version r2957 as it contains a new version of VBoxHfs-64.efi
