As anishathalye said you probably don't want to keep your git working directory on Dropbox. If you want to share a git working directory between machines, you can use a shared filesystem such as our ObjectiveFS (https://objectivefs.com). Note that if you use git with an OSXFUSE filesystem you currently need to add the "--quiet" option to work around an issue with signals (https://github.com/osxfuse/osxfuse/issues/213).
