Hello,
I just had a very similar situation as the one described here, where I too am (unsuccessfully) trying to install OpenBSD vs.7.1 - on a Thinkpad P51 - to substitute MS Win10. Here the list of activities:

On a MAC with Mojave OS:
1. initialize USB flashcard: format MS-DOS(FAT), i.e. FAT32
2. check the USB volume:
$ diskutil list
3. unmount the USB volume:
$ diskutil unmountDisk /dev/DISCNAME
4. burn a raw disk image on it:
$ dd if=install71.img of=/dev/rDISCNAME bs=1m
5.
$ diskutil eject /dev/DISCNAME

On a LAPTOP Lenovo ThinkPad P51 (2017) with MS windows:
1. BIOS set up: no 'secure boot' + active 'UEFI mode' + 'CSM support' + set USB HDD as first bootable device
2. plug the USB flashcard on the USB 3.0 port
3. choose the USB HDD bootloader and load:
3.1 the OpenBSD/amd64 BOOTX64 3.59 fails, and no installation prompt is given.
The final result is what appears in the
boot> as:
cannot open hd0a:/etc/random.seed: Invalid Argument
booting hd0a:/bsd: open hd0a:/bsd: Invalid Argument
(...)
and another series of other booting directories with 'Invalid Argument' .
As a last attempt, I tried to invoke
$ boot> bsd.rd (the Ramdisk kernel), but to no avail.
Thank you in advance for your feedback!
