Standby Problem iMac Mac OSX fixed !


Do you have problems with your iMac going into standby? How many times did you reboot, resetting the PRAM? OK, here is a solution for you folks who have an external WD (Western Digital) MyBook Studio connected to their iMac:

Remove the WD drive manager and anything related to it, reboot and your problem will be solved. This f*@&%$§ing software prevents the iMac going into standby or sleep. I can imagine that little HD apps from other HD manufacturers might cause the same trouble.

Just in case you don’t know how to reset PRAM (Parameter Random Access Memory):

  • Remove the file:

HD /Library/Preferences/SystemConfiguration/

  • -> trash it. The system might ask you for your admin password.
  • Close all apps. Reboot your machine. After the screen goes blank, press and hold ‘p‘, ‘r‘, ‘command ‘ and ‘option ‘ at the same time. All four keys. Keep holding them. Don’t let go when you hear the first sound. Keep holding them until you hear the third sound, then lift your fingers and your machine will boot up normally.
  • Go into System Preferences -> Energy and modify the settings to your gusto.

Enjoy a clean and timely standby in the future! Unlike prior versions of the Mac OS, Mac OS X 10.6.5 does not store network settings in PRAM. If you experience a network issue, resetting PRAM will not help.

If PRAM is reset, you may need to verify your time zone, startup volume, and volume settings using System Preferences. Certain firmware updates may reset PRAM as a normal part of their installation process.

If you ever should need to reset the SMC (System Management Controller), proceed as follows:

  • From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off).
  • Unplug all cables from the computer, including the power cord and any display cables.
  • Wait at least 15 seconds.
  • Plug the power cord back in, making sure the power button is not being pressed at the time. Then reconnect your keyboard and mouse to the computer.
  • Press the power button on the back to start up your computer.
