I wonder if other Mac users are able to play BOTM_27? One difference between my setup and yours, Alan, is that I have other BTS installs on other disks inside my MacPro. If I read it correctly, you only have one system installed whereas I have three = 2 - 10.5.8 Leopard and one SnowLeopard. I noticed something weird when installing - the other disks seemed to be accessed somehow or maybe it was just an illusion. I searched to find recent updates there but couldn't find any. I tried booting from them and running MacBUFFY but no luck there either. Could this configuration create some ambiguity for the MacBUFFY install? I also have a BootCamp partition for Windows XP and a botched Parallels install on the Leopard system I don't frequently use - I could get Parallels to work with Windows Civ but every reboot meant a major re-install and I gave up. Also, when I try to double click on the BOTM_27 file, it says that the BTS install is on a virtual disk and cannot be accessed. This may all be irrelevant but these things always make me wonder.
