Well, considering the current state of macOS, 👋 I have to reboot every 4-8 days or so. Either on my M1 MBP or my Intel Mac mini, after days of uptime, some kind of memory issue gets going and everything either crashes or becomes so slow I have to reboot. There's also the issue (for me, at least) of just looking at the Notification Center, and just scrolling thru causes a kernel panic.
I am old enough to remember OS X being great at Memory Management and having a 2010 MBP go almost 45 days without a reboot. But macOS is not OS X
