Question: Sleep mode, 10.9.5

Hello again!


My wonderful iMac refuses the sleep mode.

On the firs attempt it sleeps 2 - 3 hours, then wakes up and refuses to sleep again.

I have to switch it off...:(

Can´t upgrade because all my musical equipment must be renewed then, i´m to poor...

Thanx for helping, Olaf

iMac, OS X Mavericks (10.9.5)

off power, as in Shutdown from the Apple menu...?

or

off power, as in unplugged or switch off from the outlet...?


There is no need to remove the power from your iMac unless you are servicing it, worried about a lighting storm or something of that nature.


Personally I sleep my Mac's 24-7 and never have any issues. I only shut them down, when I go away for more than 2 days and only unplug them for service and electrical storms.

I have a main switch to cut everything, as there is amplifier and music devices.

It´s a 1 room flat, don´t like the lights at night.

does this affekt our discussion??

I now pulled the plug on the mac as they said at support, we´ll see if that resets something.

It used to work and sleep properly when i bought it but since almost 2 years.... no sleep....

Is there cocaine apps??

Switching off the power can disrupted the iMac's internal System Management Controller.


I would suggest,

1. Resetting the SMC again.

2. Plug the Mac's power cord in before the main switch, so that it always has continuous power.

2. At night, shut the iMac down using the Shutdown menu and switch off the other devices.

3. In the morning, startup the iMac and switch on the other devices.


Then I would test it like that for a few days and see if that cures the problem.


I believe that you are referring to Caffeine.... and NO that will not help you with this problem.

Sorry to hear that! If it started happening again after you switching off the power or disconnecting it from the AC power. Then you need to make an appointment with your local Apple Authorized Service Provide and have it check out. I would not bet on it, but suspect that the Internal PRAM Battery needs to be replaced.
