Lenovo ThinkPad 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

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
