Thanks to structure's advice, my Poser 11.2 Mac installation problem is resolved. I had not deactivated my PoserPro 11.1 before installing 11.2, and this resulted in a registration problem (stuck on the bond ware registration/ too many licences screens) I dragged the poser application to Trash and reinstalled 11.2 from the poser software.com .pkg download. All works well now on both Macs which I use. Thanks for the excellent support!
