Hi, which OC version do you have?

I managed to install Big Sur using your EFI, thanks a lot! Wifi, touchscreen seems to work, I will try to test it more tomorrow

Tried this one too and same bootloop after first reboot during install. Anyone have working EFI for 1012 G1 with SATA SSD, not NVME? I updated without big issues my other hacks ( Lenovo T440s and HP 800 g4 DM) but idk what's wrong with this one...

I tried with this one, I managed to boot installer and start install, but after the first reboot, I have boot loop when trying to boot macOS install. Edit : I have a sata SSD, not nvme.

Still have issues

I just tried to boot Big Sur install USB drive with Sitam70 EFI and still have KP with "failed to detect super IO chip" error.

Thanks, is this EFI working with a G1 model?

I have kernel panics when trying to update from Catalina to latest Big Sur using Sitam70 EFI... Do you have any instructions ?

Can I update to last Big sur update with this OC config and version?

I fixed it using DW1820a instructions. Touchscreen works too, I cleared NVRAM and it worked. Thanks a lot.

Well I erased disk and fresh installed Big Sur, it works good, but I still need to fix bluetooth and touchscreen (wifi works, card is DW1560)

OC shows this when I boot USB: OCS: No schema for Base at 0 Index. context Patch OCS: No schema for BaseSkip at 1 Index. context Patch! OCS: No schema for ForcebooterSignature at 8 Index. context <Quirks> OCS: No schema for AppleInput at 1 Index. context UEFI

Installation ends after some reboots as usual, but now when I try to boot macos from opencore (still from USB), progress bar starts at 90%, and then at 100% computer reboots. If I start with Clover, it get stuck on apple logo.

Big sur installation drive boots, I'm trying to update

Well, i just realized I put EFI content directly in EFI partition, not in EFI/EFI/... It boots now Thanks for your help

I only found Big Sur on AppStore. Downloaded it and created installation disk, then mounted EFI partition and put EFI folder from github. I still can't boot USB drive. I'll try with another USB drive, but I used this one to install Big Sur in another hack last month without any issues...

Disk util to format it to macos extended. Put EFI folder in EFI partition of USB drive. Yes same laptop (t440s)

I created bootable USB drive, with EFI folder from github. Made some changes for my hardware (wifi card, screen) but kept SMBIOS from my current Clover install. When I select my USB drive in boot menu, I can't boot it, it shows boot menu again. I cleared NVRAM before doing this.

My config with Clover and Mojave had SMBIOS with MacBook air mid 2013, (my CPU is i7 4600u). On Big sur EFI folder, SMBIOS is set to MacBook pro, 11.1. I just tried with my previous SMBIOS infos but I can't even boot on flash drive with OC.

Thanks, I'll try. Which changes to SMBIOS?
