Take a look at BBB docs.
Connect provided USB cable to OpenBSD usb port. Its preinstalled Linux should boot up ...
Check what is provided through dmesg

Check cdce man page
The cdce driver provides support for USB Host-to-Host (aka USB-to-USB)
bridges based on the USB Communication Device Class (CDC) and Ethernet
subclass
First connect network
doas ifconfig cdce0 inet 192.168.6.1 255.255.255.0
You may SSH to the machine with
ssh debian@192.168.6.2
# pw: temppwd
In some way the bone have 192.168.6.1 so you only need to specify IP on your side. How to know what a suitable IP is over cdce is unclear.
Then connect to USB mass storage device
disklabel -h /dev/sd1c
doas mount /dev/sd1i /mnt/usbdisk/
Open START.htm for start instructions. But this does not work through regular browser on OpenBSD for some reason. Possibly because of access rights to mounted file system.
On macOS
When connected over UWB USB mass storage will be attached automatically.
You should start by opening file:
file:///Volumes/BEAGLEBONE/START.htm#step2
When connected over USB your computer will get IP 192.168.6.1 and the bone will get 192.168.6.2.
You may SSH to the machine with
ssh debian@192.168.6.2
# pw: temppwd
You may open a web browser to the machine (chrome)
