#778 An error occurred while retrieving the list of supported forcefields

[Anonymous]

Downloaded prebuilt executable. Molecule visualizes, but extensions don't work.
When I click on optimize geometry or any button in extensions I get an error like this.

An error occurred while retrieving the list of supported forcefields. (using '/Applications/Avogadro2.app/Contents/MacOS/obabel').

I did install openbabel via Brew.

Please help, I'd like to try the new Avogadro.
