I’ve bought a used 2022 HP Elitebook 845 G7 Ryzen Pro 4750u so I can try to install macOS Sonoma on it for $165. Everything seems to work well except sleep and sound from Realtek ALC285 that doesn’t work with AppleALC.kext but the VoodooHDA.kext works quite well. I upload . You can try to get yours to work.
Install VoodooHDA.kext on Sonoma 14.7
Open a terminal and type the codes
curl -sL https://raw.githubusercontent.com/alvindimas05/VoodooHDAInstaller/refs/heads/main/install.sh | bash
Go to security and enable security for voodooHDA and reboot.
The graphics VRAM is stuck at 512MB from the bios and the Smokeless UMAF doesn’t seem to load for me to increase the size of the VRAM in the bios.
The battery does last about 3 hrs with Sonoma even without being able to sleep.
The BCM94360NG doesn’t seem to work with this Laptop. The Windows driver doesn’t load the WiFi with correct driver. Bluetooth disconnected and connected every 10-20 sec. Very unstable, so I have to use Intel AC-7260 to have both Intel Wifi and Bluetooth working without Airdrop.
