... resolved sort of... updated virtualsmc without the extra battery / dell / sensor files... Then was able to install Release Candidate 2... Have not traced down which file caused this...

I have Big Sur Beta 8 on this machine... But when I attempt to install Release Candidate 2, the boot loader hangs as show in the image... What is this hanging at? Please help...

Has anyone tried booting with the latest Clover?

I traced it back to two items A. the USB kexts (used the ones from your EFI folder) and B. This patch for the caddy... "Try adding this patch to Kernel patching, works for Catalina, not sure still for Big Sur Identifier = com.apple.driver.AppleAHCIPort Find = 40600200 Replace = 00000000 Comment = Patch Hotplug / Caddy" Will upload the EFI that works shortly...

this was the update install for Beta 9... There is no full installer for Beta 9... SHOULD I do a Beta 8 install over what I have and then install Beta 9? the Beta 9 install has already installed... OR just wait for Beta 10...

This is my EFI folder... EFI.zip

I do not know how to fix this. Please help...

I updated KEXT and OpenCore... now this is where the boot ends up...

Big Sur Beta 9 hangs at this point with the Beta 9. Well... it hangs for 5-10 mins... reboots then proceeds to the same spot.

I will upload my EFI file later today... All seems to be working now...

That worked... will test the drive read write shortly i was able to format and partition

Yes.. the caddy that usually has a CD or DVD drive... One can put an SSD or hard drive into that slot as a 2nd drive. (backup drive, extra data HD...)

2nd SATA port identifies a HD, but cannot partition / erase / read /write to that drive...

Installed to a blank SSD... Working with the last EFI posted... Will be fine-tuning it.

I tried resetting NVRAM and/or clearing NVRAM and that didn't work...
