I’ve got this. Check phone, 45 sec left of a 20 min timer, etc.. What’s really weird is the wake-up alarm where I get up at the right time even if I forgot to set an alarm. This also works for one-off events so it’s not just my body getting up at the same time every day. E.g. I once had to wake up at 4:15 AM instead of my usual 8:00 to drive two hours to work (long story) and set my alarm to 4:15 PM accidentally. I ended up checking my phone just to see that it was 4:20 AM and I was only off by 5 min.
MacOS of course, or Win11, or Garuda. Depends on how I feel or what I need to do. No it was not made by Apple.
