DW1820A on HP EliteBook 820 G3 Catalina 15.5

I decided to try the less expensive BT 4.1 and Wifi combo dw1820a for my Elitebook 820 G3 hackintosh instead of the more expensive dw1560 M2.

Before we tape all the pins recommended by other people, download Windows drivers and install them first to see if they work, if they work then chances are the OpenCore will work too. I had problems with Clover not to boot or booted without WIFI and BT not handoff supported.

• Download the Windows 10 drivers from here
• Download macOS Catalina kexts from here. Put them into the Kexts folder.
• Install Kexts in kernel of the OC config file
