OS X / nRF Sniffer v2 / Wireshark 2.5.0 Crash

Hey Everyone ... Looking for some ideas / help with crash involving nRF Sniffer v2 and Wireshark. Specifically I have an older White MacBook that I use for sniffing and nRF Connect. Recently I tried to update everything to the new(er) version v2 of the sniffer, and while the install went fine, Wireshark crashes every time I try to *start* a "capture".

Specific Setup is:

2010 MacBook (4GB Ram) / El Cap 10.11.6 / Wireshark 2.5.0 / Pyserial 3.4 / Python 2.7.10 / JLink 6.16c / Nordic Dongle (pca10031) with the correct firmware.

Long story short, when I install the Nordic python sniffer files in the "extcap" directory, Wireshark will crash when I try to start a capture (NOT at startup / launch). If I remove the nRF sniffer files, Wireshark runs normally (i.e. when I start a capture on say an ethernet port, it works correctly without crashing). I could post a crash report, but I'd rather not ... essentially it's showing a bus error (exc_bad_access) which seems to indicate that Wireshark is trying access something in memory that it shouldn't ... Anyone have any thoughts?
