On my machine, I am able to sync all content across all Helix projects
On my colleagues machine, she doesn't see any check boxes or projects at all with no error displayed.
According to Kamsar, https://github.com/SitecoreUnicorn/Unicorn/issues/108, this may be due to any of these conditions not being met:
MultipleConfigurationsExist && configurationHasAnySerializedItems && configurationHasValidRootPaths
But they should all be met in this case. Any suggestions? Is there a Unicorn log I can check?
