I had to pull Signal GH from the App Store two days ago because mach_absolute_time which is based on CPU clock cycles returns quite different values on my Mac Mini than it does on an iPhone 5S, and a quick hack I had done to fix the build for Xcode 8 resulted in a severely degraded user experience.
Well, thanks to the magic of Expedited Review, it's back in the Store. Thanks Apple and my apologies to any customers that had a bad experience.
