I installed IB Gateway Standalone verion (952) for Mac using this file
https://download2.interactivebrokers.com/installers/ibgateway/stable-standalone/ibgateway-stable-standalone-macosx-x64.dmg

Once installed I've found the *.jar file are placed under ~/Applications/IB Gateway 952/jars instead of ~/Jts/952/jars

There's actually no such directory as ~/Jts/952/jars

Am I missing something obvious?
