I'm not sure I've encountered a single bug in the half year or more I've had this. I don't ask a lot of it, to be fair. I guess Firefox as my main browser really drains the hell out of the battery, which is annoying. Not really a bug.
Reviews on tech boards about macOS are similar to reviews for apartment buildings: why would anybody bother writing a good one? Complaints and issues bubble to the top.
It's extremely frustrating when you're just trying to work and your OS gets in the way _and_ everyone online just says, "Well, it works for me!"
Post your issues/an example then. I'm legitimately curious.
