First, OpenBSD won’t run on HFS+. It needs an OpenBSD MBR partition which disklabel will then subdivide into smaller disklabel partitions which will be formatted with FFS. The documentation says to leave the second partition as “unused” in Disk Utility (i.e. not HFS+). I’m kind of doubtful that that will fix your issue, though, because fdisk should be able to read the partition map regardless. I’m not sure why you’re getting that particular error. I’d recommend giving the FAQ a read on the web site. It has more info on partitioning. If you’re new to OpenBSD, one thing to understand up front is that the system documentation is really good. You will actually find helpful info if you read it.
