Q: Wake from Sleep, Error

Here is another problem with my iMac:  literature from Apple-itself called Putting your iMac to Sleep reads,

 

To _wake_ [Emphasis _I_ added, Twice  :-) ] your iMac from sleep, do one of the following:



Press any key on the keyboard  [NO]


Click the mouse  [NO]


Press the power button on the back of your iMac  [YES, my iMac behaves just-as I would Expect from the first two, above!]


 

Does anybody else see these, please?  What can I do, if Anything?  Please let me know.  Thank you.

iMac (21.5-inch Mid 2011), OS X El Capitan (10.11.3), 4 GB of RAM

    This?  Please report the problem to Apple — they have a lot of documentation posted, some that looks correct, and some that might not be.  There's usually a contact link at the bottom of the web page.   (The folks at Apple don't read all the forum postings, so they might not see a report here.)

    Try these in order testing your system after each to see if it's back to normal:

     

    1.  a. Resetting your Mac's PRAM and NVRAM

         b. Intel-based Macs: Resetting the System Management Controller (SMC)

     

    2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:

     

         Boot to the Recovery HD: Restart the computer and after the chime press and hold down the

         COMMAND and R keys until the Utilities menu screen appears.

     

    3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.

     

        When the recovery menu appears select Disk Utility and press the Continue button. After Disk Utility loads select the

        indented Macintosh HD entry from the the left side list.  Click on the First Aid button in the toolbar. Wait until the operation

        completes, then quit Disk Utility and return to the main menu.

     

    4. Reinstall OS X: Reboot from the Recovery HD. Select Reinstall OS X from the Utilities menu, and click on the Continue button.

     

    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

    Bob,

     

    If you have a Bluetooth keyboard and mouse, go to System Preferences...>Bluetooth>Advanced...and ✓ Allow Bluetooth devices to wake this computer.
