Question: Sleep Wake Failure
I need help, my computer is constantly being rebooted because of the problem "Sleep Wake Failure". My attempts to fix these permanent reloads do not help, I reset PRAM, I also checked the computer for errors and testing the equipment through the D key, all tests did not reveal problems. I also read a lot on the forum how to fix this problem, through system settings - energy saving - remove all the checkmarks, and still the computer reboots. The Imac computer was bought in 2013 and worked for the "Mountain Lion" and for all this time never this was not, often restarting the computer with other operating systems
Now the mass of the OS of High Sierra is version 10.13.1
I will be glad to any help in solving this problem.
iMac (21.5-inch, Late 2012), OS X Mavericks (10.9)
