Late 2013 iMac Won’t Shut off

My iMac won’t shut down at all. I press the shut down button, it goes through the normal procedure, and then it just remains on a black screen with the mouse still active. I can move the mouse around, but it shows literally nothing else. No amount of waiting will get it to finally power down. The only way I’ve found is to hard boot it by holding the power button. I would prefer not to do this forever so any ideas?

Likely a holdover 3rd party kext or app...


˜What all 3rd party extensions are you running?

EtreCheck is a simple little app to display the important details of your system configuration and allow you to copy that information to the Clipboard. It is meant to be used with Apple Support Communities to help people help you with your Mac.

Pastebin is a good place to paste the whole report...

Workable but harder for me to work with...the Note tool on the bottom of this editor's toolbar, as shown in the image, to copy and paste the output from EtreCheck.

Great, thanks....


Uninstall CleanMyMac per their directions.


This is a big problem...

Virtual Memory Information:

Physical RAM: 8 GB

Free RAM: 16 MB


It's not showing what is using that.


Open Activity Monitor, Show:>sort on CPU%, see if anything using too much CPU%, click on Memory tab see what is using most Memory.

Ok I’m trying to run that Etre Check right now, do I need to allow the full drive access? Also I do need to point out that MacOS is now outdated and needs to update but of course I can’t because I need to shut down in order to complete the process. I doubt that’s the issue but maybe it could be useful.

More info with Full Access may help, butI'm thinking we will find out without that. "_

Hey, sorry I didn't reply sooner. I checked into the RAM and CPU usage. It looked fine when I check it now, however, when I did that EtreCheck I think there was quite a few tabs open by Chrome which always eats through RAM. HealthMonitor for some reason taking up about 1 GB of RAM. I've never used it before. Does it come with Mac or did something else install it? In terms of third party extensions I have refrained from using any thing that seems even remotely suspicions. There is one app though. I wanted to capture some audio from my Mac and quickly found out that I needed a third party app to do that. So I downloaded iShowU. I've check multiple times before and after installation and it seems to be reputable and heavily downloaded. Though recently things seemed to have gone wrong with it. One day, it just wouldn't capture any audio at all. So I tried to uninstall it through their built in application. It went through that procedure fine, but it still displayed as an audio device. Then I tried reinstalling it. Now the installer is about 4/5 of the way through the instillation and won't close. I am very aware that going through with that last step was probably a mistake. So now I have a different request from this community. What should I do about that as well. And also, I have a flash drive with my original boot up system available. If it comes to it, I will just reinstall everything from that. That is if there is nothing else to do, because I have lots of video files and projects on here that I would prefer not to get rid of. So, I am terribly sorry that you have to read this essay I put together, but if the easiest thing to do is just to reset the entire system and start over, then I'll do it. If there is a way to keep my video files and projects on this Mac without a flash drive then that would also be great. Thanks and sorry for the 72 questions I have.
