Just did a fresh install Mac OS Mojave (10.16.4)
After installing the SANLink3 T1 driver (SANLink3T1_MacDrv_V1_52_2) when ever I reboot my MacBook Pro (2017) the bluetooth is not working.
The error is "Bluetooth: Not available"
If I reboot the system without the SANLink 3 connected, all works fine. When I connect the T3, my bluetooth keyboard/mouse stops working for 10-15 seconds and then all works fine (10GBe and Bluetooth, but when I reboot, it doesn't work anymore)
I think I has to do something with the kext loading (while booting Mac OS).
