MacOS sometimes leaks traffic after system updates

it also leaks the audio of tabs before logging in.

Even though I had disabled all 'restore' applications features, macos sometimes decides to 'start' browsers BEFORE logging in after a restart AND those start auto-playing audio from whatever was paused before the reboot (or many days before).

Since then I went rather deep disabling that feature, but I never trusted it.

I can’t think of anything I want less from a laptop than it playing sound when I open it… and yet apple bring it to me as though it’s a feature.

That’s an unfair characterisation. It’s just restoring windows, some of which happen to be browser windows, which then load a website with auto-playing video or audio that (unsurprisingly) starts playing. No one is selling it as a feature to “play sound when waking up from sleep”. I bet that if you configured the browser to never auto-play, this wouldn’t happen.

To clarify, because commenters seem to be misunderstanding my point: I’m not defending the functionality, I think it’s wrong. My sole quarrel is with the characterisation that Apple is selling it as a feature, when they’re not. Let’s not ascribe wrong (or at best unknown) motivations to behaviours, as that makes is less likely they will be fixed.

Does it matter if the end result is that the browser plays audio before you've authenticated your user session?
