Review on 🔌 Fenvi T919 Adapter: Plug and Play WiFi Card for macOS PC with Continuity and Handoff Support - 1750Mbps 5GHz/2.4GHz MIMO 802.11ac Beamforming+ by Flex Graham

T919 works natively in macOS on my Hackintosh but was causing power issues on my Gigabyte Z390 UD motherboard (version 1.0 with the latest f10c firmware). The computer started turning back on after a system shutdown/shutdown and then goes into an endless reboot loop until you unplug the cable. It also happens randomly on power up (before the BIOS loads, so it's definitely not an OS issue). Toggling the ERP settings and the dummy load settings in the BIOS fixes this, but it's not ideal as changing the ERP setting affects other peripherals. On macOS, attempting to hibernate turns off the system instead. Card pulled out and sleep/shutdown/power on worked perfectly again. I found a forum post where the post author had the same issue on a Gigabyte Z370M D3H. He switched to a cheaper Fenvi HB1200/1200M and it worked as expected with no power issues. I just made the same switch and it works for me too. If you have one of these motherboards and downgrading from AC1750 to AC1200 isn't a big deal, I would go with the HB1200/1200M instead.
