Question: iMac keeps waking from sleep every minute
Ever since upgrading to High Sierra, I've noticed that my iMac is constantly waking up from sleep to do some background processes for a minute or two, and then returns to sleep for 10-30 seconds before waking up again.
Is there a way to check what processes are constantly waking up my iMac?
Here's a snapshot of my Activity Monitor. Does anything look out of the ordinary?
