Mac OSX app force closes after ~10 seconds

I've attached below the error log that I encounter. I downloaded the latest version of the app from the [downloads](https://keybase.io/docs/the_app/install_macos) page.

```

Start with the attached installer log and the macOS app entry point at /Applications/Keybase.app/Contents/SharedSupport/bin/keybase. Investigate the updater, service, and KBFS installation failures involving the LaunchAgents paths, then reproduce the reported force close. Done means the app remains open and the listed components install without those errors.
