Can't load folders locally

Keybase GUI Version: 1.0.47-20180410052738+f705a9510f

Trying to go through process of allowing local folders, click on "Allow" in the Security & Privacy settings, but nothing appears to happen. Here are the system logs:

Start by reproducing the local-folder permission flow in the Keybase GUI on macOS, focusing on what happens after clicking “Allow” in Security & Privacy. Compare the result with the keybase.Helper logs, especially the kextLoad requests for kbfuse. Done means the permission action completes and local folders load successfully.
