Hi all,
My XPC service is crashing on Mavericks 10.9.5 and on Mountain Lion 10.8.x
and I am not able to figure out the problem. I have pasted the logs below.
The same code works perfectly fine on latest *10.10 Yosemite*.
I am not sure what changes to be done in my code to make it work on
Mavericks and Mountain Lion OS X. Any help is greatly appreciated.
