Silly question but we read all the time those complains from tech journalists or 'apple geeks' about those macos bugs, while I'm not a huge fan of the OS myself, my complains are usually UI or performance related, rarely on actual bugs: curious, is there an obvious, known list of bugs those guys are talking about?
