Hey bjgo can you provide/confirm your WiFi/BT setup? I recently completed an almost identical build as you, and everything works well except Bluetooth. Bluetooth is present and will connect, but the signal is
very weak and the range is poor (about 5 feet). Just putting my hand in front the antennae causes the BT signal to break up. When I connect to my 2.4Ghz wifi band, the BT signal is even worse and breaks up constantly. When I turn Wi-fi off, BT will not connect at all.
More recently, BT will no longer turn
off - the "Turn off Bluetooth" button in settings is greyed out.
My WF//BT card installed is the Broadcom BCM94352Z and the kexts installed as outlined in the guide here:

SMBIOS is set to Macmini 8,1. I believe I have the USB ports configured correctly - I'm using USBinjectall.kext and a have a custom SSDT patch that gives me 15 ports total - 6 usb2 + 4 usb3 + BT.
Any idea what is going on? Is this a macOS issue or a Hackintosh/kext issue or something with my home wifi?
Thanks.
