Hi Matt,
It looks like you have lots of choices to choose from as per handing
the 'Ooops - Wrong OS' situation. Often times my suggestions are not
received as 'the best', but - undaunted - here comes another one.
Anticipating the inattentive User and otherwise taking control of the
situation so that bad-things do not happen may require you to do the
following:
Create an app (bundle) that is 10.0 compatible. When it wakes up,
have it read the Gestalt for the OS Version, decides if the User should
see a dialog (or not). Then either quit after the User has been
informed of the improper OS situation - or - Launches the REAL app
which is another app (bundle) contained in, for example, the Resources
folder of the initial app.
They used to talk about 'the Mac way' - My thought is that wresting
such decisions (and the potential for disaster) from out of the hands
of the User is the desired approach. It's a tad more work up front for
you, but you can also check if the app is beyond the version for which
you have tested and put up a dialog about THAT, as well - perhaps
advising Users to check for an updated version at your website. For
instance, the whole notion of 'StartupItems' is supposedly being
deprecated and will replaced with a thing called a 'Bootstrap Daemon'.
If your software HAS a 'StartupItem' component that gets installed, you
may want to be doing this kind of forward-looking OS-check check,
anyway.
Only trying to be useful - please don't yell or hit,
Lance Drake
