Did Apple lose some critical people in the last year or so? Johnny Ive we all heard about. But maybe more such important foundational people on systems and core OS side also left? I'm guess this because the drop in quality in both iOS and MacOS even in released software is significant that regular people are feeling it. I seriously hope this is a temporary glitch and I won't be forced to figure out a new system setup (back to Windows? Or Linux or ChromeOS?) for my day-to-day.
