Whenever I use pmset sleepnow
in Terminal (even with sudo
) I get this error:
Unable to sleep system: error 0xe00002e2
. I have no idea what's going on. Please help!

Are you on the latest version of your firmware? This thread mentions that there were problems with old firmware.– JMY1000Mar 4, 2016 at 20:19

I don't have any updates available in the App Store... Does that mean I have the latest firmware?– atiritMar 4, 2016 at 22:20

No, firmware updates don't show up on the app store. Follow this guide.– JMY1000Mar 5, 2016 at 22:25

I struggled with the problem for months without any luck; the computer was unable to sleep, the sleep option on the apple menu was greyed out, pmset -g assertions (the most popular suggested solution to find ongoing processes) didn't return any result, and resetting the SMC didn't work. Today I finally found the solution that worked for mine
sudo pmset -a disablesleep 0
Hope this works for others too!

Welcome to Ask Different! The background info is good, but the info about the solution seems to be missing. Can you provide some details, links, or references?– AllanMay 21, 2016 at 13:09
