Try use -igfxvesa -lilucpu=8 dart0= rootless=0 vsmcgen=1 -lilubetaall keepsyms=1 -v

 

My Lenovo is from signature E470 Thinkpad

 

The same EFI install maybe not work properly for boot normal.

Ok I got there!!!!! - This is how I got past the contant reboots trying to upgrade to Beta 2- I used Crazybirdy's 'InstallScript_1016 full app' to download Beta 2 (Took approx 30 mins and places it on the desktop). After the download finished, I clicked on it and installed it directly over Beta 1 and the magic started. At times it looked like it was hanging but I let it do it's thing and after 4 reboots it went to the desktop :thumbsup_anim:

I am hoping Beta 2 reduces the "ghosting" i am getting when downloading.

This gets left on my screen when downloading with Chrome.

Graphics doesn't appear to be the issue.

I'm curious about this "Train" feature. I know Windows 10 uses the term "Ring", for Fast Ring/Slow Ring on public betas, and some other "rings" for their internal dev team. This IMHO might be a counterpart for the macOS team.

Nice! I also have Designare. would you be able to share your EFI? Thanks.

Here. Folder for Skylake+. in some cases need change things in Booter Quirks

EFI BigSur Skylake+.zip

Some observations

Boot from USB / Disable booter-fileset-kernel and booter-fileset-basesystem

Boot from SSD / Enable these options if need

Work in beta 2 too

Create your USB stick with createinstallmedia and paste this EFI folder into EFI partition, reboot, Reset Nvram

I tried updating directly from Beta 1, and I stuck at “forcing cs runtime for entitlement com.apple.rootless.restricted-block-devices” while booting the beta 2 installer. Any idea? 
macOS 10.15.5 and 11.0 B1 works fine, and I can also boot into macOS 10.15.5 recovery.

I’ve built a USB installer with BS b2, and no matter which SMC I use (VirtualSMC with or without boot flag vsmcver=1, 2 or 3; RehabMan’s FakeSMC; or Slice’s FakeSMC3), resetting NVRAM (either via OC “Reset NVRAM” option or Clover’s F11 key), I still get the SIGABRT errors. Last OC built from sources of July 7 around 8PM EDT. This is annoyingly disappointing :(

 

Catalina used to boot just fine until it was wiped for a VM based DMG image; BS b1 boots just fine, but I cannot upgrade to b2.

 

Any more ideas?
