To paraphrase some Apple employees: "Radar or GTFO." As many Apple persons are pointing out this week, unless you report bugs (called "radars") to Apple, you are doing nothing to improve the circumstances of which you complain.
As Chris Rawson has pointed out repeatedly over the years, Apple's "beta" releases are what normal people would refer to as alpha. On a good day. If they're feeling generous.
Apple offers a simple guide as to whether you should or should not file a bug report: the answer is always Yes.
Beta participants are encouraged to file radars even when the issue seems trivial, only happened once, seems "obvious", or may be a dupe.
