Doesn't the MacOS kernel use some bastardized version of device tree? I'm not sure of their commitment to UEFI/ACPI..

- marcan_42 6y agoOn ARM it does, as I mentioned in the article (though it isn't directly useful to us, as it's too different from Linux ones). But yeah, assuming there will be no Intel machines in Apple's line-up at some point in the future, I wouldn't be surprised if they drop out of the Forum.
- monocasa 6y agoThey even use device tree on x86 too (in addition to ACPI/EFI). The plaintext password and user guid is passed in chosen fields for instance when boot.efi unlocks an FDE disk.
- my123 6y agoIt pre-dates Device Tree support on Linux for Arm. Both have a common ancestor (OpenFirmware, notably used for PowerPC Macs)
