Q: energy saver

Please read If your Mac doesn't sleep or wake when expected - Apple Support.

Do you mean your Mac won't "Shut down" or that it won't "Sleep" ?

What all 3rd party extentions are you running?

Does your Mac shut down if you choose Shut Down... from the Apple menu?

For Mac shut down (a total power down), one thing to remember is this point from the Energy Saver Help file (arrow below). Your Mac will not shut down if it is "Sleeping" when the shut down time comes. Basically, for automatic shut down to work, you need to set the computer "Sleep" slider to the extreme right (to "Never"), but you can have the display go to sleep at whatever interval you want (something similar to the screen shot at bottom).

You're welcome. It took me a while to figure that out for myself.

One thing I forgot to mention... If some programs have unsaved data, the computer will not shut down. For example; I have MS Word on my Mac. If I have an open Word document that I was working on and not saved the changes, the shutdown on the Mac will stall at the point where Word is asking me if I want to save the changes or not. And that is far as it shuts down. If the changes to the Word document had been saved, the Mac will complete the shutdown as desired.
