Hi!
I do some project on os and everywhere I get the same error libsystem_kernel.dylib`__ulock_wait:
-> 0x7fffa4bdc31e <+10>: jae 0x7fffa4bdc328; <+20>
Where it appears and how to track it I do not know, I need help. Thank you!
my system:
MacOS Sierra Version 10.12.6 (16G29)
Xcode version 8.3.3 (8E3004b)
P.s.
my bt all looks like this:
