STEP 1: Purchase OS X Lion from the Mac App Store

2. It will boot directly to a familiar Mac OS X Installer complete with Disk Utility. 

3. Open Disk Utility, partition a empty hard drive.

4. Install OS X Lion or Mountain Lion

6. Use your installer to boot your new installation.

3. Instal the Kext form the package you downloaded early on to your hard drive.

What works: Almost Everything works expect  sleep and sata DVD Drive.

Hi, thanks for this guide. Sounds like it's a straight forward installation.

 

One comment though: if you use myHack to install Mac OS X, you should install the additional kexts to /Extra/Extensions as opposed to /S/L/E which, ideally, should be left vanilla or as vanilla as possible. All those kexts you listed as SLE targets can go to /E/E. It also looks like some are not necessary or appear ex-ModCD and can therefore be replaced by more recent kexts.

 

Lets get this integrated to EDP. Are you (and your XPS) available for testing?

Hi all.

I have successfully installed this in my xps 720. I have followed all the steps as it says.

I have rebooted and boot the installation.

I get still waiting for root device . I have tried booting from different USB ports as well no luck.

I have tried many flags n luck.

 

 

Can someone tell me please what I am doing wrong. ??? I have a 150gb raptor hdd to install to and I'm installing from a 15gb flash.

The mountain lion is an untouched iOS image of a retail disk which I own.
