lenovo-t480-hackintosh-macos-ventura

Working (compared to other setup I've found):

FileVault2
Physical mouse buttons with VoodooPS2
Brightness Hotkey F5,F6
Fixed LED blinking after WAKE/SLEEP
~~FAN speed in HWMonitor~~ (Fan speed is correctly reported within YogaSMCNC)
No color banding, Display is correctly seen as 24-Bit Color (ARGB8888) : issue reported by @bugraduz
HDMI output enabled automatically at boot/wake : issue reported by @opatotto
No sound distortion with headphones : issue reported by @bugraduz, fixed with ComboJack for alc257 https://github.com/hackintosh-stuff/ComboJack/commit/28e35e5f8613195aff627d78362ee3f4cd8397a3

Tested with:

T480 i7-8650U FHD, 32GB RAM, NVME, nvidia MX150 deactivated in DSDT/SSDT
macOS 13.5 (22G74)
Wireless DW1560, NGFF Broadcom BCM4352 802.11ac with PCID [14e4:43b1]
Wireless DW1820a : use config.DW1820a.plist
Wireless BCM94360NG : use config.BCM94360NG.plist (reported by @opatotto #16)
CPU i7-8650U : use https://github.com/stevezhengshiqi/one-key-cpufriend for correct power-state/energy saving

If you're using AirDrop (file sharing with another apple product), remove "io80211.awdl=0" from config.plist

F4 key : Mute/Unmute microphone, with LED
F7:dual display, F8:Wi-Fi, F9:preferences, F10:bluetooth, F11:keyboard,F12:launchpad & Fn-Space:keyboard backlight
Fn+ESC : switch function/media keys

SSD tricks:

Disable hibernation (speeds up entering sleep mode)
sudo pmset -a hibernatemode 0
Set hibernatefile to /dev/null so it will not be recreated
sudo pmset -a hibernatefile /dev/null

Untested:
built-in intel wireless & bluetooth should work
remove AirportBrcmFixup.kext, BrcmFirmwareData.kext and BrcmPatchRAM3.kext
put itlwm.kext and IntelBluetoothFirmware.kext
