... after several minutes I manually shut it down.
What's going on?
You mean stuck at black "shutting down" screen ?
Think that's happened to mine once. The hang at the black shut down screen.
Yeah, what's the deal?
Yes. Cursor remains and I can move it across both screens. I don't understand why and SSD takes that longs to close files and shut down.
AFAIK, it's nothing to do with the SSD, but the native setting is to wait 20 seconds for every single software that not responding during shutdown. So, if you have 20 stuck process. That will cost you 5 minutes waiting time. If you have 100 non responding process, that will cost you 25min to shutdown. Amazing Apple default that long to wait but not just kill the process. TBH, I don't think they really that care about losing data.
There was a simple script available back in Mavericks specifically deal with this issue. It change the 20s waiting time to 1s, therefore, greatly speed up the shutdown time. It works all the way to Sierra, but not sure if that still work in High Sierra.
It may cost you some time to search that script (it should be somewhere in the OSX forum, most likely in the Mavericks forum), but worth to try.
Personally, I just close all my apps before shutting down.
Could help a lot without installing additional scripts.
I normally close all of apps which is why this is puzzling to me.
Close all apps doesn't mean that you kill all process. There are still hundreds of process in the background. In fact, you should able to dig out which parts ware stuck in console.
Good to know.
Next time I'll walk away from it.
So how do I "dig them out"?
Waited between 20-30 minutes last night before I shut it down.
(I have 5 external SSDs - would that make a difference?)
My 5,1 never took longer than two or three minutes running the same OS. I cloned the apps and data and copied them over.
How about if you shutdown the Mac by terminal command?
sudo shutdown -h now
sudo shutdown -h now
Screens would gpo black, but the cursor remained and could be moved.
Not an issue since I eject all external drives and close all programs. Back to normal.
