From the beginning (1987), I've ALWAYS turned my Macs off at night.
But...
I go even further than that.
My desktop Mac (a Mini) and accessories are plugged into a surge supressor/power strip.
When I'm done at night, I not only power down the Mac, after it shuts off I reach down and flip off the entire power strip, to "cut it from the mains".
In the morning, I turn the power strip back on, then press the Mac's power-on button.
I've done it this way for 37 years now.
Guess I'll be doing that until the end...
