Bug

If you'll try running log scanner manually with python, and not with docker, it'll probably crash with these messages:

objc[35301]: +[__NSPlaceholderDate initialize] may have been in progress in another thread when fork() was called.
objc[35301]: +[__NSPlaceholderDate initialize] may have been in progress in another thread when fork() was called. We cannot safely call it or ignore it in the fork() child process. Crashing instead. Set a breakpoint on objc_initializeAfterForkError to debug.

Explanation

That issue is caused due to some new security changes made in High Sierra macOS that are breaking a lot of Python program that use forking. For further explanation, please check out this link. In general, a new mechanism aimed to detect the usage of forking (which the log scanner most certainly does).

Solution

You can either run the scanner with docker, as described, or set a temporary environment variable which will disable that fork safety mechanism:

export OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES

enjoy :)
