I just updated from HS to Catalina (10.15.6) and have a few issues I can't seem to solve. One is that the dark mode doesn't stay dark. Whenever it's been on sleep for a while (>few hours/overnight) it changes to Light. What gives? Is there anyway I can force it to stick through the terminal or something? I've seen a lot of grumbling about similar issues early on but thought it's been fixed by now, no?
