arahmxxn Posted December 12, 2021 Share Posted December 12, 2021 Hey, I tried to use Jake Lo's opencore 0.7.5 efi and put it on my usb drive next to com.apple.recovery.boot folder. the couple things I changed were config-intel to config as he mentioned, and I also updated my deviceplatfrom according to his MacBookPro 12.1 but everytime I choose my usbdrive, it only shows my windows 10. I've tried dortiana opencore guide before, but his efi is a state of art and I really want it to work. I can undertstand whatever step you would guide me through. thannks!

Moderators Jake Lo Posted December 12, 2021 Moderators Share Posted December 12, 2021 Make sure you set BIOS to UEFI / AHCI Disable secure Boot Your USB installer, make sure it's formatted to GUID / Journal Extended Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted December 12, 2021 Moderators Share Posted December 12, 2021 What's the source of your installer and how did you create it? I see you mention com.apple.recovery.boot, I don't remember seeing that in my installer. I use the createInstallMedia command from MacOS Link to comment Share on other sites More sharing options...
arahmxxn Posted December 12, 2021 Author Share Posted December 12, 2021 yes, I used dortiana guide for creating mac recovery usb using python. here I found you helped someone here when he got kernel panic using also the same method. here you recommend it for him to use your opencore efi's 0.6.6 but I guess he passed cause his harddisk was already formatted into APFS, I couldn't get my efi to work at 1st because I got dsmos then I googled and found the help post mentioned above. I believe it might be a dualboot issue but I'm not sure how to remove dualboot from your efi. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted December 12, 2021 Moderators Share Posted December 12, 2021 are you sure the recovery file is Big Sur? Try setting in Config file under UEFI/APFS MinDate=-1 and MinVersion = -1 Link to comment Share on other sites More sharing options...
