T440s can dual boot Sequoia and Mavericks!

So this has to be one of the widest range of macOS’ fully bootable and fully functioning on any hardware. I believe that I can go for one more version, Mountain Lion 10.8.5 final update added Haswell + HD5000/4600 kexts? But for later.

Working on Mavericks:

same as Sequoia plus now the webcam works and appears on USB for some reason

Doesn’t work:

Card reader (kext won’t load)

Changes:

use itlwm, known version to work

https://github.com/OpenIntelWireless/itlwm/issues/949

no heliport so must hardcode wifi networks in Info.plist

Use Rehabman VoodooPS2 2018-0506 (latest has random kernel panic), can’t use modern touchpad kext because VoodooInput tries emulating Magic Touchpad 2 which didn’t exist back then :>

—— Overall just some amazing nostalgia. All the old sounds and the old icons are a beautiful trip down memory lane that I can take with me anywhere I go, because the same config can boot Sequoia with all modern amenities!
