 Greetings:

 My Emacs app has been hanging on my ever since I updated to macOS Sierra
 (I followed the instructions on Migrating and re-built everything from
 scratch including emacs-app). When it hangs, I am able to obtain the
 following error.

 Google helped me find Emacs bug 23924 [https://lists.gnu.org/archive/html
 /bug-gnu-emacs/2016-07/msg01177.html], which appears to be this issue as
 well. Within that thread, a developer, I think, created a patch and it
 appears to have been verified to work. I think the patch was for 25.1.50.
 Any assistance you can provide would be much appreciated. It's possible
 that updating the port from 24.5 to 25.1 may fix this issue if the patch
 had been applied. Please let me know if you have any questions, comments,
 or concerns. Thank you for your help with this.

 Kind regards,
 Anthony
