I was talking with my computer Guru the other day and he had originally told me that when we went to OS9 it would be the end for MORE for several reasons, primarily the excision of several support libraries. Even more recently he told me that the "classic" provisions of OS10 would allow for the runniing of programs such as MORE etc. I am going to keep on this, but I am curious as to whether anybody has heard anything to that end, or (hopefully not) to the contrary. Frankly, where MORE don't run, I don't go.

The primary challenge for MORE was the migration from the Motorola Complex Instruction Set CPUs (CISC) to the Reduced Instruction Set (RISC) PowerPC Central Processors.
More never had trouble running on Apple's Unix (AIX) I doubt it will balk at MacOS X. I am not set up to test at the moment but I will try to get you a confirmation on that.
I agree with your devotion, my copy of More lives in my PowerBook and goes with me everywhere.
