As if Apple land was free of issues, remember those wonderful keyboards, Snow Leopard, Tahoe among many other examples, or any Linux laptop for that matter.

Or the Installer.app, at least from 2015 to whenever they finally switched to image-based updates.

A percentage of users were "unlucky" to hit a bug where Installer.app would end up in infinite loop trying to unpack a pkg file when updating OSX. My personal record is minor update that ultimately took a week.
