The reason I am asking this question is because yesterday, my iMac shut off randomly by itself. 2 mins later I turned it back on, started searching about why a Mac might shut off by itself, then bam! Within 5 mins of turning it back on, it shut off by itself again.
So I unplugged it for the night, and then I looked up how to do an SMC reset/reboot and then did it.

Then I realized… I do an SMC reboot every single night because I first power off my iMac, turn off the power bar/strip, and unplug the power bar/strip from the outlet in hopes of saving a bit of energy during the night.
My questions are:
-
Is it harmful that I shut down and unplug my iMac every night? (basically reseting the SMC every night)
-
Is it better to just put the iMac to sleep instead of shutting it down, or is there rarely any difference?
