Hi Guys,

I am running a bit of a problem when installing packages on mac (OS 10.14.3).

This is what Julia returned after entering Pkg.add(“Gadfly”)

> **ERROR:** failed to clone from [GitHub - JuliaRegistries/General: The official registry of general Julia packages](https://github.com/JuliaRegistries/General.git), error: GitError(Code:ERROR, Class:SSL, unexpected return value from ssl handshake -9806)
