10.9.5 slow to wake from sleep

Ever since updating to 10.9.5, my 2011 iMac takes way too long to wake from sleep. Like, 20 - 30 seconds, where it used to be nearly instantaneous. Needless to say, I'm not digging this new feature. I saw an almost identical question that was answered, but that was for laptops, and involved something called "power nap".


Any help? Please?

iMac (27-inch Mid 2010), Mac OS X (10.7.4)

OS X Mavericks: Reset your computer’s PRAM

A small amount of your computer’s memory, called “parameter random-access memory” or PRAM, stores certain settings in a location that OS X can access quickly. The particular settings that are stored depend on your type of Mac and the types of devices connected to it. The settings include your designated startup disk, display resolution, speaker volume, and other information.

Note: To print these instructions, open Help Viewer’s Action pop-up menu (looks like a gear), then choose Print.


  1. Shut down your Mac.
  2. Locate the following keys on the keyboard: Option, Command (⌘), P, and R. You will need to hold these keys down simultaneously in step 4.
  3. Turn on your Mac.
  4. Immediately press and hold the Option-Command-P-R keys. You must press this key combination before the gray screen appears.Continue holding the keys down until your Mac restarts, and you hear the startup sound for the second time.
  5. Release the keys.

Resetting PRAM may change some system settings and preferences. Use System Preferences to restore your settings.
