I've updated my MacBook Pro 2019 before I saw the HN post, the updated went smoothly without any issues (so far).

I've done the same update on my Mac Mini 2018 and now the fan has stopped working after reboot. Tried to reset NVRAM and SMC without any luck... the fan is still unresponsive. Apple diagnostics even confirms this by giving an error code PPF003

My mid-2015 mac (last REAL MacBook IMO) won't install it at all.

It says it's installing, I reboot, it does some stuff, then I come back and the update isn't applied.

Quality stuff!

If it's any consolation, I really like the keyboard on this latest air. Gave me reason to move off my 2012, the REAL last real macbook imo with everything replaceable/upgrade-able with a Phillips head screwdriver and 20 minutes of your time.
