- Late 2015 iMac 21.5; 3.1 GHz Intel Core i5; 8 GB 1867 MHz DDR3, Mojave.
I just switched from my old 2009 iMac to a new 2015 iMac, both running Sierra.
I've set my computer to never go to sleep, and my display to turn off after 10 minutes.
Sometimes the display turns off as ordered, and sometimes it doesn't. More often than not, when it turns on unexpectedly, it doesn't turn off 10 minutes later.
The following are probably meaningless, but I'd rather give you more clues than fewer:
The old computer did not have this problem. It is currently wireless to the router and the printer. It is on, but almost never used.
Frequently, when I'm ready to stop working, I will impatiently turn off the display manually (shift/control/eject) rather than depend on the 10 minute setting, but I have no statistics that relate the unexpected turn-on with the manual turn-off.
Although there is no keyboard or mouse activity, the backup system (CrashPlan) does run in the background every 15 minutes.
The new machine has the mouse, router, and printer all wireless. Keyboard is USB-connected.
The old machine has only the keyboard wireless.
Can anyone explain this peculiarity, or better yet, offer a solution?
