MacBook Pro won’t sleep automatically — no process preventing sleep according to pmset. What's going on?

Just found SMBL on my system. Deleted it.

Is there a way to know if SMBL gets added?

Or do you have to use your suggested Terminal commands to find out if it's there?

.

For me it was definitely a print item stuck in the print queue. Open Print & Scan in system preferences, select any printer(s) with a red or yellow badge, and then click the "Open Print Queue" button to show the print jobs and delete any that have not completed. Seems too darned simple to work but it did.

I have a mac pro which has a simlar sleep problem. Went through your 4 steps and this is the output:

Any thoughts on what is causing my computers imsomnia? Hope it is of acceptable protocol to jump in with a response to you. Never really used the forms before and not sure.
