My app is targeted at 10.4 and better. I know that whatever I do,
people are going to download it and try to use it on earlier versions.
I don't want to use an installer, just the drag-to-Applications thing.
However, as currently configured, on pre-10.4 systems the app just
fails to launch without a word of explanation. The syslog shows that
the cause of the crash is "failed objc_getClass(NS**tigerOnlyClass**)"
What's the nicest way of catching this problem without using an
installer? If the app won't launch in, say, 10.3, how can I tell the
user very politely that they need to upgrade if they want to use my
app?
