No. The main thread is blocked waiting for another Cocoa thread. It's waiting on an internal pthread condition variable. > * frame #0: 0x00007fff89524136 libsystem_kernel.dylib`__psynch_cvwait + 10 > frame #1: 0x00007fff8fa8b560 libsystem_pthread.dylib`_pthread_cond_wait + 693 > frame #2: 0x00007fff8dea323e AppKit`-[NSViewHierarchyLock > _lockForWriting:handler:] + 323 There must be some other thread which is going to signal that condition variable under some circumstances. In all likelihood, that other thread is blocked on something else, so you have a pseudo-deadlock. Show the backtrace of all threads. Or a sample report, which has similar information.
