E6530 Big Sur installation

Recommended Posts

<_< Tuh tuh tuh...

 

Big Sur was announced compatible with models not older than MacBook Pro late 2013 and MacBook Air 2013. None of these include Ivy Bridge/HD4000 platforms. Expect support to start at Haswell only...

This being said, Big Sur beta so far supports Ivy Bridge HD4000 graphics (IntelHD4000 + Capri framebuffer kexts are present) so you should be Ok for the time being. Maybe not when final version gets released at fall.

I used the EFI from the E6540 thread and updated the kexts...

I was able to boot to the install screen.

Formatted a blank SSD and installed.

A couple of reboots then...

I was able to get to this point in the install process.

It seems to be hanging on igpu

Strange thing...

 

The laptop no longer boots from and/or recognizes any of the SSD drives...

Even when booting from a USB drive, no internal drives are recognized or even seen by the computer...

Could this be a hardware failure? 

I have a HD in the cd-rom caddy and not even that drive is seen...

AND

It does not even post... only the logo appears

When I take all the drives off, it will boot off a usb drive...

Did you press the Reset NVRam from OC Picker?

Seems to be an issue on some hardware. Did it on my E6430 and it'll only show the Dell logo.

I had to remove the battery, the HDD, move the ram to a different slot. After several attempts, I was able to get to the BIOS, reset to default and change the BIOS settings again. It then finally boot.
