A post yesterday from someone actually trying to build Gtk on a Tiger system raises a question I've been mulling for some time:
Is it time to pull the plug on the older versions of MacOS?
In fact given today's security environment I think that supporting ancient and no-longer updated MacOS versions is a disservice to users, who might get the message that it's OK to expose their insecure systems to the internet because someone out there still supports their system.
