Remember, if you want to run on "all" systems, you need to go to Carbon
CFM ;) We actually did this, because we wanted OS 8/9 users to get a
reasonable error message. I wouldn't suggest that everyone needs to go
to that much effort, but in our particular case, our target audience
has demonstrated a penchant for not observing the min-spec, and then
for calling tech support when things don't display perfectly clear
error messages.
("All" is quoted because CarbonLib is still required--that only brings
you back to Mac OS 9.0 stock, really, though 99% of 8.1+ users will
have it by now if they are still trying new software. For users of 8.0
and earlier, there's just no hope at all of doing the right thing for
them, but that's really fine with me. :) )
Actually, come to think of it, didn't Omni do a cute trick where under
OS 9, they explicitly don't set the package bit, so when you double
click the ".app", its folder opens, and inside (along with the Contents
folder) is a readme explaining that you need OS X? That seems clever.
