Question: OSX 10.9.5 on MacPro shutting down instead of sleep - why?

Since I run OSX 10.9.5 on my MacPro activating the sleep function results in shutting down of the system. Stangely I can start again with the click of a button, but the Mac does a reboot.


I would very much like to have this sleep function again.

Mac Pro, OS X Mavericks (10.9.5)

How to know if you need to reset the SMC

These symptoms might mean that an SMC reset is necessary:

  • Your computer's fans run at high speed, even though it isn't under heavy usage and is properly ventilated.
  • The keyboard backlight behaves incorrectly.
  • The status indicator light (SIL), if present, behaves incorrectly.
  • Battery indicator lights, if present, behave incorrectly on Mac notebooks with a non-removable battery.
  • The display backlight doesn't respond correctly to ambient light changes.
  • Your Mac doesn't respond when you press the power button.
  • Your Mac notebook doesn't respond properly when you close or open the lid.
  • Your Mac sleeps or shuts down unexpectedly.
  • The battery doesn't charge properly.
  • The MagSafe power adapter LED, if present, doesn't indicate the correct activity.
  • Your Mac performs unusually slowly, even though its CPU isn't under an abnormally heavy load.
  • A computer that supports target display mode doesn't switch into or out of target display mode as expected, or it switches into or out of target display mode at unexpected times.
  • The illumination around the I/O ports on a Mac Pro (Late 2013) doesn't turn on when you move the computer.
