Black screen with cursor on logout OS X 10.11.X

[Chuey]

Hello,

Clients of mine have been using 10.10.X for some time now and I have started upgrading many machines to OS X 10.11.4. One thing I've noticed is on logout the screen will display a black screen with just a cursor. The only thing I've found to resolve this issue is to force a reboot by holding down power. It might not happen every time someone logs out but it is frequent.

Has anyone else seen this issue?

Thanks in advance.

Yes, this is for personal systems and deployed systems. Ever since 10.113 and .4 its been really buggy.
Sometimes our users get fan speed increase from a cold boot into the OS and these are on maxed out 15-inch Retina MBP 2015.

And just last night had a handful of machines attempting to do a logout or a shutdown and the cursor + black screen issue occurred, tried to remote into it to give it a soft shutdown but had to force shutdown most.

Thanks @walt . At least I know it wasn't an image I created using AutoDMG. Ugh, I love Apple so much.

Quick question, do you happen to have a Policy Banner at all? We are using 10.10 currently and they tend to do this exact thing as well. I haven't seen it at all on 10.11 due to a small deployment group currently.

@jjones we don't and some of these weren't even enrolled in casper and theyre just out of the box set-ups relatively new systems from 2 months ago as well.

@jjones Login Window Banner under config profiles is being used.

I would look at what is being launched in /Library/LaunchAgents and also at any installed plugins.
We have a had a few issues on various machines this year since moving to 10.11 and they appeared to have been caused by the logged in user not having sufficient rights to kill/quit the process.
The two items that have definitely cause it were
- HD Audio plugin for Pro Tools 11 (only required if you have HD audio gear which we don't).
- Very old Sony camera drivers (which it turns out no one used anyway).

There are probably others as well.
