Updated from El Capitan to Sierra yesterday, it took just under 50mins. Definitely the smoothest update yet for me. Great work guys
Seems like im stuck on sound assertion, and then it times out after 24o seconds.. :/ anyone have any ideas?

I had that problem on my H97N-WIFI. Do you have AHCI_Intel_Generic_SATA.kext installed to L/E?
So I added RealTek kext and nullpower to my clover other folder, and that *seemed* to do the trick.. just a fyi.. will test it again since I did this on my cloned drive first to see if it actually works.
did as said. mac restarted, loading bar appeared. After loading (took a while) a grey screen appeared with the marble of doom ... Then I waited some time, got fed up and shut the mac down (holding power button) ... My El Cap still works.
Any ideas?

FYI, I did as you suggested above. After I test booted into my cloned startup system with it's own EFI everything worked, but when I tried to restart from my main SSD nothing worked. Complete unhappy darkness. I couldn't even boot from my USB. I then took my cloned drive and EFI partition to a Mac I have in the house, stuck the drive in a HD cradle, loaded the EFI, erased it. Then I reset the BIOs from the motherboard jumper. I was able to load my original startup drive and EFI. When I added back the backup drive with the empty EFI, everything was fine. I think I'd be too scared to try this again.Here's how I did the backup of beta Sierra.
Required: Formatted spare drive with an empty EFI partition. Copy Copy Cloner (CCC) or SuperDuper.
Clone (backup) your current OS X partition to the backup drive.You can test your backup by booting into your BIOS, selecting the Backup drive as your boot drive, save and boot to the Backup drive. Everything should work fine. If so, reboot into the BIOS, re-select the installation drive, save and boot into the installation drive.
Open the Terminal and execute the following command:
Find your EFI partitions from the output of the above command:Code:diskutil list
disksXs1 > your current installation EFI partitionMount each EFI partition using EFI Mounter v3 - be sure to keep track of which EFI is what as they will both mount on your Desktop as EFI.
disksYs1 > your backup EFI partition
Copy the EFI folder (within the EFI partition) from the installation drive to the EFI partition of the backup drive.
