Successfully updated from High Sierra, 100% perfect, on my good old H81-Haswell,
EFI folder attached

lenovo has a bios whitelist so only very few options are available, seems like BCM94352Z could be candidate,
regarding the BT issue 0cf3:3004 device is included in IOath3kfrmwr.kext (see attached screen shot)
also renamed on SSDT section, now blocks shutdown,
i'm pretty happy with actual performance and compatibility, don't think is worth dedicating more time,
thanks for your support
