How to Symbolize OSX Crash Logs

Unfortunately, xcode does not yet have support for importing OSX crash logs and symbolizing them. Therefore, you must use the command line and a little bit of manual work.

Find your dSYM file.
1. Assuming you are using xcode's archive functionality, open the Organizer window from the Window menu.
2. Click the Archives tab.
3. Right click on the appropriate build and select Show in Finder.
4. When Finder opens, right click on the selected archive and select Show Package Contents.
5. Navigate to the dSYM directory and copy the appropriate dSYM file to a temporary directory.
Then navigate to Products, then Applications, and copy the app file to the same temporary directory.

I've never had great understanding of launchctl but the deprecation of the old commands with launchctl 2 (10.10) has been terrible as all resources only cover the old commands, and documentation for Apple utilities is generally disgracefully bad, with launchctl not dissembling.

Mad props to https://babodee.wordpress.com/2016/04/09/launchctl-2-0-syntax/ which contains most details

domains

Internally, launchd has several domains, but launchctl 1 would only ask for service names,
