Q:

Emacs freezes when minimizing frame on OSX

I have had the issue that emacs will lock up (and need to be force quit)
on occasion when I minimize it.  I am almost always in org-mode, but
otherwise I can see any pattern, except that it happens while it is minimized.
I have scoured the world for a fix to this.  Does anyone know how to fix this, or at least how to figure out why it is happening?
I'm on OSX 10.11 with Emacs 24.5

A:

I have been using the ``not yet stable'' 25-rc2 build of Emacs for a month without any lockup issues.  So it seems @lawless is correct, and this did fix the issue.
