Mountain Lion Hackintosh: How to Install OS X 10.8 (2012)

Hey guys, this is Austin and today I’m here with a tutorial
on how to create a Hackintosh with Mac OS X Mountain Lion.
There are several things to keep in mind before doing this so
please listen carefully. First of all this will not work on
all computers, you must have compatible hardware. I will have
the info for my build in the description of this video but if
you want to know more a great place to check out is It’s a great resource for finding what hardware
is best suited for OS X. One thing to keep in mind is that this
isn’t for everyone. Lots of things can go wrong so if you’re not
prepared to do a little tinkering and research, Hackintoshing
probably isn’t for you. Once you’re sure your computer is
compatible you’ll need a couple more things. First of all is a
computer running OS X with the App Store installed. You’ll also
need an 8GB or larger USB drive to install Mountain Lion and I’ll
have the one I’m using listed in the description. I also highly
recommend having a hard drive or SSD that’s totally free of data
that can be used just for Mountain Lion. First step is to grab
your Mac and download Mountain Lion from the App Store. If you’ve
already bought it you can navigate to the Purchased tab and grab
it from here. If you don’t have Mountain Lion I’ll be giving away
a promo code for it on Twitter in the next couple days. Once it’s
downloaded the Installer will pop up but instead of running it
just close it. Now open Disk Utility and plug your USB drive in.
Select it and then hit the Partition tab. Select 1 partition, click
Options and choose Master Boot Record, name it USB and finally under
format choose Mac OS Extended Journaled. Then click Apply.
Now you need to download UniBeast for Mountain Lion. I’ll have a
link in the description but you will need to create a forum account
to download. Once you’ve done that open UniBeast and click through
the installer. It will ask you where you want to install so choose
your USB drive we just made. You’ll find a couple options for legacy
support as well as preparing UniBeast for laptops so choose either
of these if you need them. Now just give the installer a few minutes
to load Mountain Lion up. Time to move over to your soon-to-be
Hackintosh. At this point you’ll need to plug the USB drive into
your computer and enter the BIOS. This step is going to be different
depending on what motherboard you have but it’s fairly straightforward.
First find boot options and select USB hard drive as your first boot
device. Then double check that your motherboard is set to AHCI mode.
Save the changes and it should boot from your UniBeast drive. Select
USB and try to boot. If you have issues like I did try again but this
time type GraphicsEnabler=No in the prompt. If you’re still having
problems try booting with the -v flag and noting what error you get.
Once it boots you should see the OS X installer. We’re most of the way
there however there’s one more thing to do before installing. Come up
to the top menu and select Disk Utility. Here you should see all hard
drives connecting to your computer. Pick the one you want to install
Mountain Lion on and select the Partition tab. In options select GUID
Partition Table then choose Mac OS Extended Journaled as the format
and name it Mountain Lion. Then click Apply. Close Disk Utility and
go through the installer like normal. When it comes to the install
screen just pick the Mountain Lion disk and then click install. This
will take quite a while so be patient and let it do its thing.
Once it’s done you should reboot back into the UniBeast drive. This
time select Mountain Lion and then complete the installation. Nicely
done, you now have OS X installed on your new Hackintosh! Now is the
time to start experimenting around and checking to see if everything
works. My build works nearly perfectly out of the box with the exception
of the on-board audio which I don’t use anyway. More than likely you’ll
have a few issues but no worries, just take note of everything that
isn’t working. At this point you can just be done however you’re still
booting from the UniBeast USB drive. There’s one more optional step to
finalize your installation and fix any problems you might have. Head
over to the downloads section on and download MultiBeast
for Mountain Lion. Again go through the installer until you reach the
options. Here you need to choose EasyBeast or UserDSDT. For me I can
use UserDSDT by itself but depending on your build you may need to use
EasyBeast or UserDSDT with a prebuilt DSDT file. Beyond that just
select the drivers that you need for whatever isn’t working on your
computer and you’re good to go! Congratulations, you now have a 100%
working Hackintosh! If you found this video helpful be sure to leave
