Hello, can someone shed some light on this please. My iMac 2013 has big problems waking up in the morning after being put to sleep. fro the night (suspend activity). Goggled it and interesting solutions came out but there's one strange thing. I cannot find the option "Prevent the computer from going to sleep automatically" on my System Prefs Energy pane. See attached pictures please. It's French but one can see the option is missing. 5 options are showing on a picture I took from the Web and only 4 options on the capture I took of my computer. It runs 10.13.16. Thanks so much. Merci beaucoup.
