yoga-720-opencore's Issues

Kernel panic at boot

Hello, thank you for your job!
Unfortunately when I start the installer i get a kernel panic.
Bios configured as yours, same laptop:
Lenovo Yoga 720
i5 7200u (yours is 8th gen Coffee Lake, mine is Kaby Lake)
Intel hd 620
8gb ram
Samsung NVME (to be changed… I’ll do when I’ll get to boot the installer, otherwise if I can’t succeed it will be useless).
I removed driver and kexts related to Broadcom network device since mine is different (I will install the same when I’ll manage to boot the system) and I disabled network adapter from bios, so I would exclude this could cause any problem.

Right before the kernel panic:
IMG_1960

The kernel panic log:
IMG_1962

MacOs Big Sur.
I already tried to disable devirtualize MMIO. No difference.
I think I will try asap to build a new installer from scratch, maybe we could solve the installer problem you reported in the second step.
Thanks.
Best regards

Disk Utility not seeing upgraded SSD

Hey! I replaced the native SSD with a 1TB upgrade from crucial (CT1000P5PSSD8), however, I am still unable to see the it in disk utility when I load the installer from USB. Any potential fixes?
