[coreboot] Re: Query regarding coreboot
Hi- Apparently Matthew (mj...@srcf.ucam.org) made some modifications to allow booting OS X without Clover. I'm not sure if his changes are current or if they're specific to the X210 which they were made on / for, but I had the same question and that was the answer I got at the time. Never tried it though, I'd suggest you ask him for the details, as I don't have any specifics.

To answer the original question, I think not. Not on its own. macOS needs Clover. Clover needs UEFI. UEFI means Tianocore for payload. So coreboot+Tianocore+Clover, where Clover would be handled like any other bootloader eg. grub. I'm not sure if there porting Clover as a coreboot payload is necessary, practical, or even possible. At the very least it is a lot of work.

[coreboot] Re: Query regarding CoreBoot
One would use coreboot + Tianocore + OpenCore. Whether a particular board has the required hardware support, or whether coreboot provides the firmware structures MacOS requires is another story (and yes, I know part of that is what OpenCore works around). FWIW I know of a few users with Acer c720 and Dell 13 7310 Chromebooks running MacOS on my current coreboot 4.12/Tianocore-based firmware using OpenCore On Mon, Jun 8, 2020 at 10:31 AM Evgeny Zinoviev via coreboot wrote: > > coreboot doesn't boot the OS, it performs hardware initialization and passes > control to a payload (SeaBIOS, GRUB, Tianocore, etc. - these are payloads). > So you would have to use something like clover anyway. > > On 6/8/20 6:22 PM, lol wrote: > > Hi, I wanted to ask if coreboot is capable of booting macOS.

coreboot doesn't boot the OS, it performs hardware initialization and passes control to a payload (SeaBIOS, GRUB, Tianocore, etc. - these are payloads). So you would have to use something like clover anyway. On 6/8/20 6:22 PM, lol wrote: Hi, I wanted to ask if coreboot is capable of booting macOS.
