Ok, digging around, looks like it's a problem with watchman. I uninstalled that - after going back to Node 6.9.1 and ng still wasn't working, saw that watchman was trying to run. Uninstalling watchman seems to have worked.

@jtsom thx, had the same issue 👍

Strange thing is, on another system, having Watchman installed is not causing any problems.

I can run Node 7 just fine with angular-cli without watchman on this system. Add watchman, and it hangs. (For what it's worth, the Ember cli command does the same - not surprising as they're similar)

More testing. I tried installing watchman again, and ng was still hanging.

This time I uninstalled watchman (brew uninstall watchman) and also removed the launchctl item (launchctl remove com.github.facebook.watchman) to make sure it was gone.

ng worked fine. So I reinstalled watchman and started up an angular 2 app - and it seems to be ok now. The launchctl item reinstalled itself - I can only assume something got corrupted?

YMMV
