Inspired by Marco Ceppi's DS_store question, I became curious about what the current preferred mechanism for submitting bug reports and feature requests to Apple for their software. I'm aware that they have the internal RDAR bug tracking system, and that there is an Open RDAR project to crowdsource the tracking of issues, but I'm at a loss as to the preferred channel to submit something.
Is there a public-facing portal for submitting issues?
