Dual boot MacOS Big Sur 11.5.2 for daily use, Windows for gaming.
CPU: i7 10875H 2,3 GHz 8-Core
GPU: RTX3080
RAM:32 GB 2933 MHz DDR4
Laptop Make and Model: Razer Blade Advanced 2021
Screen: 15" 240Hz QHD

Wifi/BT Card: Replaced Intel card with Broadcom BCM94360NG
Storage: Added second SSD for MacOS: Sabrent Rocket 1TB NVMe PCIe M.2
BIOS revision: Razer BIOS 1.03 (no mods)
WORKING:
Screen works out of the box. Use HiDPI to get scaling https://github.com/xzhih/one-key-hidpi
Audio was an absolute pain to get working, but in the end I think I just missed the correct layout-id from the wiki. Took me about three weeks of troubleshooting until today it finally started working. AppleALC Layout-id 47
Keyboard: working, used KarabinerElements for CapsLock light. Backlight dimming works, but not able to control the RGB lighting colors. (it'll cycle through the spectrum slowly). Tried osx-razer-led and Razer MacOS but neither recognise the keyboard.
Trackpad: working with full gestures. Stole most kexts for this. Palm rejection is not nearly as good as on an OEM Macbook.
Wifi/BT works out of the box with the Broadcom replacement.
iServices working: iMessage, Facetime, TimeMachine, Airplay, Handoff, Apple ID login, Keychain, etc
CPU Power Management works, unable to Undervolt due to BIOS lock.
SD Card reader (using RealtekCardReader kext)
Battery readout (battery life around 3-4 hours on light use)
Opencore GUI UEFI menu + Boot chime
NOT WORKING:
dGPU for obvious reasons
HDMI out (wired directly to dGPU)
Keyboard RGB color control
CPU Fan control (I have VirtualSMC and co running, but get a "No Fans Detected". Any advice welcome!)
NOT TESTED:
Thunderbolt
Sidecar (need a new iPad...)
Used Dortania's Guide for initial setup. Had trouble fixing the trackpad and gestures, so I did steal some kexts and merged config.plist to make mine work. MacOS response is fast and smooth, like any MacBook you can buy. I love having faster hardware and gaming options while still being able to use MacOS for daily stuff! Let me know if you have any questions/requests
