OS X issues

[Matthias Clasen <matthias clasen gmail com>]

Hey John,

since you are one of our OS X contributors: It seems the 2.24.2 release from this week has some issues on OS X:

https://gitlab.gnome.org/GNOME/gtk/issues/1517

https://gitlab.gnome.org/GNOME/gtk/issues/1518

We could really use your help here! I'd like to do a follow-up release before X-mas to fix

a few other issues, and it would be great to take care of the OS X problems at the

same time.

Thanks in advance
