UniBeast + MultiBeast is the easiest method to do a clean install of Mac OS X Lion or update any Snow Leopard system. The following guide requires no coding, terminal work, or Mac experience of any kind.
Install Mac OS X Lion Application
Mac OS X Lion USB Thumb Drive
STEP 3: Install Mac OS X Lion
You may have to type extra command line flags to reach the installer.
- Asus Motherboard + NVIDIA Graphics – type PCIRootUID=0
- Unsupported graphics – type GraphicsEnabler=No
- Boot in Single-user mode – type -s
- Boot in Verbose mode – type -v
- Boot in Safe mode – type -x
14. Close Disk Utility
15. When the installer asks you where to install, choose Lion, or your existing install.
16. Upon completion, restart system
The installation is complete, but the drive isn’t bootable yet. Boot from the USB again, this time choosing Lion.
STEP 4: Post-Installation Using MultiBeast
MultiBeast is an all-in-one post-installation tool designed to enable boot from hard drive, and install support for Audio, Network, and Graphics. In addition it includes System Utilities to repair permissions and a collection of drivers, bootloaders, config files and handy software.
1. Complete Mac OS X Lion setup.
2. When you arrive at desktop, open Safari
Note, if Safari crashes, disable Web Content: Browser Plug-Ins under Preferences>Security.
3. Browse to tonymacx86.com and log in. If you don’t have a user account, create one!
4. Go to tonymacx86.com/downloads to download the latest MultiBeast
5. Go to the DSDT Database to download your motherboard’s DSDT
6. Open Downloads folder and move the .aml file to the Desktop
7. Open and run Multibeast’s UserDSDT
8. Restart system
If your drive doesn’t boot on its own, and you get an error referencing boot0, fix it using the methods listed here.
You may also use MultiBeast to install further drivers to enable ethernet, sound, graphics, etc… Be sure to read the documentation provided in MultiBeast Features.pdf about each option. Both UserDSDT and EasyBeast install the proper bootloader by default, so you’ll not need to check that option.
You now have a fully updated bootable version of Mac OS X Lion on your CustoMac! And a handy USB rescue drive to boot from in case things go pear-shaped. It’s easy to get frustrated, but don’t give up! If you get stuck, there are many users with similar hardware in the tonymacx86 Forum to provide support. Special thanks to everyone in the community, and our Mods for testing!
