[gtk-osx-users] Support of Older OS X Versions

[John Ralls <jralls ceridwen us>]

Christoph's email about pango modules and gtk-mac-bundler reminded me of another issue: GLib 2.46 includes an 
implementation of GNotification that uses NSNotificationCenter, available only in OS X 10.9 and later. 

How important is it to everyone here that we continue to support older versions? 

AFAIK every Mac built since 2010 is able to run OS X 10.11. My 2010 MBA certainly does; I bought it when the 
10.7 developer preview came out so that I could test Gtk on 10.7 (darn good thing, too, there were some 
serious issues). Gtk has several runtime checks where we have different implementations for pre-10.7 systems. 
It would be a nice cleanup to get rid of them. Conversely it wouldn't be too hard to fix GLib so that the 
notification feature is enabled only on 10.9 and later and earlier versions just drop the notification. 
Making that change in git would likely get some push-back from the Gtk core group, but gtk-osx has several 
patches that the core group didn't like so one more is hardly a big deal.
