Since it's impossible to ever fix *all* bugs in anything but the simplest of codebases, the answer is... pretty hard. Businesses also do not have infinite time or money so it's logical to prioritize the biggest and most important issues and leave or ignore the smaller/less critical ones.

TBH I'm still impressed by how much improved the wireless is - in comparison, a minor login glitch while doing something that most people rarely if ever do, on a lesser used browser, on a lesser used operating system, is a complete non-issue by comparison.

Plenty of websites that rely on user logins to do anything useful at all still have glitches and issues with certain browsers, including ones more common than Safari.
