My Mac laptops typically have uptimes of months (85 days, currently). However, I am still on Mojave, and I do have 32 GB of RAM. I do routinely encounter two problems. When switching desktops while have full-screen video the cursor frequently disappears; the solution is to move up a ways until the cursor is surely at the menubar and then click, which will restore the cursor to visibility. The other problem is that audio occasionally stops working (one symptom is that pressing play seems to work but the play time never advances, and of course there is no sound). The solution here is `sudo killall -9 coreaudiod`. My Windows NUC, on the other other hand, seems to reboot itself within a week, but usually is unusable long before that because it won't wake the monitor up after sleep. And even though I disabled sleep, it still seems to not be able to wake the monitor up.
