I have the May 2004 revision of Inherit the Earth for OS X, which did run on a previous system. I've just recently reinstalled on a new machine with verision 10.4.1 of the operating system, and it crashes out after the initial volume-setting dialog. Can anyone out there confirm that this happens to them too? I can provide a fairly detailed stack dump from the crash if it'll be useful.
Please send the crash report to techsupport@wyrmkeep.com.
We did a quick check here, and the May 2004 version works OK on our Mac with either Tiger 10.4 or 10.4.1 installed.
If you send us that crash report, make sure it indicates the model of that new Mac.
