Common Issues

Connector Fails to Start

Symptoms: Status remains "Inactive" or shows error, Red dot indicator

Cause: Command not found or missing dependencies in the environment.

Cause: macOS permissions blocking access to specific folders.

Solution:

• Ensure Perplexity (or the terminal running the server) has Full Disk Access in macOS System Settings if accessing sensitive directories.
