MBA freezes overnight, will not wake.
I just upgraded to 10.15.5 from 10.14. Everything works fine except for one problem. For the past two nights, since the OS upgrade, my Macbook Air (purchased in 2017) refuses to wake in the morning. Eight hours of non-use freezes the computer. There are uploads running overnight, but these are not enough to keep the computer operational. In the morning I can hear the fans running, but the keyboard and screen are dark, and no amount of key tapping will wake the computer. I have to restart the Air to get back to work.
As you can imagine this is extremely annoying. May I have a few suggestions as how to track down this problem and make a fix? Thanks everyone.
MacBook Air 13″, macOS 10.15
