BIOS macOS Clover Critter

Status - Discontinued

Introduction (QQ Group Chat: 97986046)

Tips: If you want to use built-in network adapter, you'd better buy a new pcie card, and I suggest DW1560 or DW1830, considering about the size and space. Also, P52 does not have whitelist upon WLAN hardware, you even do not need to modify your BIOS
