Before You Begin 1. Register here at tonymacx86! If you don't have a user account, create one! 2. Get our latest UniBeast tool from the downloads section. 3. Purchase a 8GB or larger USB drive. We recommend using a 16GB drive, as some 8GB drives are not large enough to complete Step 2. The method requires 7.45GB free space. 4. Do a full backup of your system. We strongly recommend performing a full backup of your existing system using Carbon Copy Cloner. By doing this, you can always go back to your working installation. UniBeast is a tool that creates a bootable installer out of your downloaded version of OS X. In order to start fresh, you'll need access to a functional computer running Mac OS X Snow Leopard 10.6.8 or later. This is a requirement, as you need access to the Mac App Store to download OS X and create the installation drive. To start from scratch, booting the 10.6 Snow Leopard Retail DVD directly, check outiBoot + MultiBeast. For the first time tonymacx86.com is recommending Clover as your default bootloader. If you have followed updates until OS X Yosemite using Chimera, check out Clover Basics and Switching Advice. Existing Clover users may do a direct update to OS X El Capitan by simply running the Install OS X El Capitan app as normal Mac users would. Follow these steps: Direct Update to OS X El Capitan using Clover.

STEP 1: Download OS X El Capitan The full operating system is a free download for anyone who has purchased Mac OS X Snow Leopard, Lion, or Mountain Lion or has a Mac preloaded with OS X Mavericks or Yosemite. Download the Application from the Mac App Store using your Apple ID on any Mac or functional computer running Mac OS X 10.6.8 or later.1. Open Mac App Store 2. Log in with your Apple ID 3. Download OS X El Capitan The Application Install OS X El Capitan will appear in /Applications.

STEP 2: Create a Bootable USB Drive with UniBeast Take a deep breath and take your time- this is pretty simple, but it's easy to miss things if you rush. Follow each step to the letter.1. Insert the USB drive 2. Open /Applications/Utilities/Disk Utility 3. Highlight the USB drive in left column

4. Click on the Partition tab 5. Click Current and choose 1 Partition

6. Click Options... 7. Choose GUID Partition Table

UniBeast will now create the bootable USB drive. The process will only take about 10 minutes, depending on system and drive speed. Do not unplug or stop during this time. If the process doesn't complete, use a 16GB drive- some 8GB drives are not large enough. The method requires 7.45GB free space.

Clover Note: UniBeast delivers basic bootloader support based on our testing on recommended CustoMac systems. For further bootloader customization, download and run the official Clover package. Advanced users may also compile Clover by downloading the full source.

STEP 3: Recommended BIOS Settings If you're installing on a recommended CustoMac desktop with AMI UEFI BIOS, the options are simple. For other systems make sure to set your BIOS to Optimized Defaults, and your hard drive to AHCI mode. Here are standard AMI UEFI BIOS settings for Gigabyte AMI UEFI BIOS, Gigabyte AWARD BIOS, ASUS AMI UEFI BIOS, and MSI AMI UEFI BIOS.1. To access BIOS/UEFI Setup, press and hold Delete on a USB Keyboard while the system is booting up 2. Load Optimized Defaults 3. If your CPU supports VT-d, disable it 4. If your system has CFG-Lock, disable it 5. If your system has Secure Boot Mode, disable it 6. Set OS Type to Other OS 7. Save and exit.

STEP 4: Install OS X El Capitan You're almost done! All you need to do is boot from the USB drive and install! For best results, insert the USB in a USB 2.0 port.1. Turn on the computer 2. Press the hotkey to choose boot device (usually F12, F11, F10, or F8) 3. Choose USB 4. At Clover boot screen, choose Boot Mac OS X from USB 5. When you arrive at the Installer, choose language.

If you have issues reaching the installer, first make sure you're using a USB 2.0 port. If you're using a NVIDIA 'Maxwell' GeForce GTX 750, 750 Ti, 950, 960, 970, 980, 980 Ti, or TITAN X graphics card, the drivers are not natively supported. You may need to enter the boot flag nv_disable=1 to reach the installer. For instructions on entering boot flags see Clover Basics and Switching Advice.

Press the hotkey to choose boot device 2. Choose USB 3. At Clover boot screen, choose Boot Mac OS X from El Capitan 4. Complete OS X El Capitan setup 5. Download El Capitan Post-Install Tools

The Post-Installation.zip contains two custom Clover installers and essential kexts. This will provide boot from hard drive while we finish up MultiBeast 8.0. Alternately, continue booting from the USB drive. 6. Run one of the two custom Clover installers. UEFI Boot Mode (Clover_v2.3k_r3270_UEFI.pkg) is recommended for 7/8/9+ Series CustoMac desktops and all UEFI capable systems. Legacy Boot Mode(Clover_v2.3k_r3270_Legacy.pkg) is recommended for 5/6 Series CustoMac desktops and all BIOS based systems. For further bootloader customization, download and run the official Clover package. 7. Run CustoMac Essentials to install FakeSMC and ethernet support. The next steps configure the system definition, configure graphics, and provide it with a unique serial number. 8. Download and open Clover Configurator 9. Your config.plist should auto-mount. If not, choose Mount EFI Partition. 10. Select SMBIOS tab 11. Press Magic Wand Icon 12. Choose a System Definition from the list. Then choose a version of the system from the dropdown. This will auto-populate your config.plist with appropriate SMBIOS information including a unique serial number. If you're unsure what to choose, Mac Pro 3,1 will work for most desktop systems. 13. (Optional) If you have an existing Chimera SMBIOS located at /Extra/smbios.plist, you can choose the same system definition in Clover Configurator, then copy that serial number into your config.plist manually. 14. (Optional) If you configured graphics for the UniBeast installation, open GUI tab and select Inject NVIDIA or Inject ATI. 15. Save and close Clover Configurator. The next optional steps configure the system's Realtek ALC onboard audio codec. 16. (Optional) Download CloverALC110 script 17. (Optional) Browser/Click on download file 18.

Alternate NVIDIA drivers are required. 20. (Optional) Download and install Alternate NVIDIA Drivers 21. Reboot

They also will enable the latest 'Maxwell' cards to work with full acceleration- NVIDIA GeForce GTX 750, 750 Ti, 950, 960, 970, 980, 980 Ti, and TITAN X.
