zdwApple randomly closes bug reports unless you "verify" the bug remains unfixed
I recognize that this is annoying from a user perspective, but I do understand it. Not all bugs are easily reproducible (and even if they are 100% reproducible for the user, it's not always so easy for the developers). Also sometimes you make a change to the code that you think might be in a related area, and so sometimes the most "efficient" thing is just to ask the user to re-test.
When I close an old bug that is not actionable, I do feel bad about it. But keeping the bug open when realistically I can't really do anything with it might be worse.
Back in another part of my career I worked a lot with putting Macs on ActiveDirectory. And there was a common refrain from Apple about bugs in that implementation: "works on 17!".
The joke is that Apple owns the 17.x.x.x class-A range on the Internet (they got in early, the also have a second class-B and used to have a second class-B that they gave back), and what engineers were really saying is that they could not reproduce on the AD systems that Apple had setup (lots of times it was because AD had been setup with a .local domain, a real no-no, but it was in Microsoft's training materials as an example at the time...).
