Here's a quick guide to create a macOS Sierra 10.12 Public Beta Installation USB using Clover. Please note, this guide is not universal, and may not work for all systems.​


STEP 1: Download macOS Sierra Public Beta

1. Enroll in the Free Apple Beta Software Program
2. Open Mac App Store
3. Log in with your Apple ID
4. Redeem code
4. Download macOS Sierra Public Beta

The Application Install macOS Sierra Public Beta will appear in /Applications.


STEP 2: Prepare Bootable USB Drive
This step extracts the Installer contents, then installs Clover bootloader to the USB stick.

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
8. Under Name: type USB (You can rename it later)
9. Under Format: choose Mac OS Extended (Journaled)
10. Click Apply then Partition
11. Open /Applications/Utilities/Terminal
12. Type the following, enter password and hit enter. This command completely erases the USB, then creates native installer media from the Install 10.12 Public Beta Application.

macOS Sierra GM & Final Build
Code:
sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/USB --applicationpath /Applications/Install\ macOS\ Sierra.app --nointeraction
macOS Sierra Public Beta
Code:
sudo /Applications/Install\ macOS\ Sierra\ Public\ Beta.app/Contents/Resources/createinstallmedia --volume /Volumes/USB --applicationpath /Applications/Install\ macOS\ Sierra\ Public\ Beta.app --nointeraction
Upon completion, the USB will be renamed Install macOS Sierra Public Beta.

13. Download the latest version of Clover from sourceforge
14. Open Clover package installer
15. Hit Continue, Continue, Change Install Location...
16. Choose the USB, now called Install macOS Sierra Public Beta
17. Hit Customize and install Clover to the same USB using one of the following examples:

18. Navigate to /EFI/CLOVER/ and replace default config.plist with one of the attached config.plist examples.
19. Navigate to /EFI/CLOVER/kexts/other/ and add FakeSMC.kext
20. (Optional) Navigate to /EFI/CLOVER/kexts/other/ and add your ethernet kext
21. (Optional) Navigate to /EFI/CLOVER/kexts/other/ and add NullCPUPowerManagement.kext

Your Clover Installation USB is now finished.

It does not work, when I enter the above command in Terminal, I get:
sudo: /Applications/Install 10.12 Public Beta.app/Contents/Resources/createinstallmedia: command not found :(

Just fixed the path- the Application is named Install macOS Sierra Public Beta.

also can I use the config.plist I currently use on 10.11 or do I need to use the UEFI attached?
You can use your config.plist- there are no particular special settings necessary for Sierra.

I'm getting a "can't perform kext scan: no kext summary" kernel panic. Is there a fix I can apply to boot into the installation menu?
