iOS 16 might be the worst iOS to date, worse than iOS 9 imo. Otoh, macOS Ventura has been rock solid for me minus one bug I have with my iCloud Drive (but it’s been persistent since Monterey).
Mine too. Rebooted without warning. Coincidentally, my Mac Pro was knocked off wifi, literally at the same instant, but I don't see any possible way the two events are connected.
Today when the iPhone updated to 16.5 and rebooted, my Mac Pro was kicked off wifi. Just like the last time, simply reconnecting to wifi required re-entering the wifi password, which should have already been in my keychain. It's like iOS updates are doing something to the keychain, which then affects other devices on the same iCloud account also using the keychain. Very odd!!
