So is it theoretically possible to modify the memory of BW's Mac client to enable LanLat? We know the offset and value to change for the Windows client. How would one find where the offset is for Macs?

ye-old mac thread: http://www.staredit.net/topic/14464/

I think the offsets are all the same (though they possibly diverge after the unit table, it's been too long for me to say), but the endiness is reversed, so you have to correct for that in EUDs. If you are using a third party program for this, note that BW addressing is not static (tldr heinermann rant: not always) like in windows so you need a way of finding the base address or some point within BW's stack mem.

seems pretty complicated to set up a mac vm for testing.
