Thanks, I'll look into that

[jonchui]

Thanks!

Seems like it's crashing @ LaunchAtLoginHelper.swift line 29:

[jonchui]

Looks like LSSharedFileListItemCopyResolvedURL can return nil, so i just added nil check before and it seems to work now, let me submit a PR for you.

[luosheng]

Thanks for the PR. I've released a new binary. https://github.com/luosheng/OpenSim/releases/tag/0.2.0
