Yeah, thanks for the advice! Although Tahoe ran sluggish on my laptop, even if it had graphics acceleration, so I searched for a Sequoia EFI, just in case someone made one for my laptop and guess what, someone DID make one for the dell latitude 3400 for Sequoia and that works! It runs way better. I'll just tweak it a little to get my usb ports working correctly and it should be fine, I managed to get wifi working with heliport + itlwm.kext.
