Question: Computers Won't Shut Down After Connecting To Server

Hello Geniuses,


I am having a strange issue and I know it's not going to be easy to diagnose but let's give it a shot. I have two iMacs in my studio, a 4k and a 5k, both with El Capitan 10.11.2, and both connected to an ethernet network and talking to a server on a Mac Mini (latest OS and OS X Server).


I mention the server because I think it may be relevant, but that's just a guess.


Basically both of these computer have a strange inability to shut down. You choose Shut Down and they go through the motions all the way to the black screen with the spinning cogwheel, and then it just lingers there. Forever. Well, at least for 24 hours because that's the longest it went unnoticed once. Typically I wait a few minutes and then do a force shutdown. (I wait a few minutes because sometimes, not very often, but sometimes, the computers will successfully shut down.)


Both machines are wired to the server and frequently use fire sharing (SMB and AFP) to load files off of networked drives. Again, I mention this because this is the common thread between these machines that seems to be the outlier from typical usage, and I'm wondering if the connection to the server is the process that keeps the computers from shutting down properly.


If anyone can help point me in the right direction that would be awesome.


Thanks!

iMac (Retina 5K, 27-inch, Late 2015), OS X El Capitan (10.11.2), null

Answer:

Well I guess this problem is unique to me, however, if anyone else does wind up with the same issue I think I have resolved it. I changed all the file sharing preferences to just AFP (disabled SMB). This seems to have fixed a variety of issues I have been having with my network, including the iMacs that were hanging on shut down.

I just saw this. I have been having the same problem with my 27" iMac. I have 5 other macs running the same OS but they shutdown fine and they are all connected to a Mac Mini Server with 10.11.2.

Most things run well. The computer runs fine but every once in a while it will also have Finder do it's lock up and no matter how you try and restart it, you end up having to restart the Mac.

Back to the shutdown problem, Tonight I was getting ready to shutdown and made sure that all programs were closed, check. Then I thought, "maybe if I disconnect the network drives first it will shutdown." That appears to be it. It could not disconnect the network drive. It gave an error stating that I would have to force dismount and I had to click to force it. I did but all it did was...nothing. The buttons went gray like it was trying but it could not disconnect.

After about 5 minutes I then logged out, thinking it may have disconnected but didn't clear the screen. It logged out and then I clicked shutdown and it did the same thing with the spinning shutdown logo.

There is obviously a problem with the SMB because I am using it too. Some must be okay because my other macs are all connecting using SMB. Apple says we don't have much of a choice as they are pretty much forcing people to smb. Using SMB certainly does make browsing folders with lots of files much faster than AFP.

I didn't try to zap the PRAM (I did the SMC). I should try that next.

Yeah I've heard that SMB is a lot faster. I'm not exactly sure why, or how it could be faster on 1000mb/s ethernet, but if it's true then I would very much like to be able to go back to using it. If you figure anything out please let me know. Thanks for chiming in!

File transfers I don't notice as being faster only the time it takes for all the files to show up in Finder Window. I don't notice anything else though other than the only way you can use tags is to have the newest version of SMB on the Yosemite or higher server.

I wish you hadn't "given up" so quickly. I've been having this problem for many months now, and have reported it to Apple last year. I have an open bug filed (#23684301) which as of today is still open! I do hope Apple is working on a fix. I updated to 10.11.5 today on my 2 Macs and sadly this bug still exists. You should not have to downgrade to AFP in order to use such a basic function as file sharing between 2 Macs.


I encourage you to file your own bug report at bugreport.apple.com - the more people who report it the better. And Apple does not monitor these forums so we are just talking to each other here.

There are times that unmounting from the client still doesn't work and shutdowns fail. If the computer goes to sleep, then awake, then unmount, it seems to work fine. Or, I can unmount that client from the server software and then shutdown always works too.

This is a common issue and have more than two medium size companies where this is occurring. I was having issues shutting down without connection to the server and solved these by fixing permission in Mac HD/System/Cache, by forcing apply to enclosed items,

Turning off SMB fixed shut down delays thank you, hoping one day that SMB will be fixed but it has such a controversial history on Mac for so many years that I am not surprised this was the culprit. Also managed to solve permission issues but this maybe because I setup an new permission group rather than use the built in group Staff.

I used the common (command i ) on the Systems/Cache folder, then click the arrow next to Sharing & Permissions.

Unlocked the padlock bottom right with password.

Then used the gear icon and selected "Apple to enclosed items.." in the pop up

Cant remember if this was before update to El Cap but update still did not fix shut down after opening files on server.

Turning off SMB on server fixed shut down issues and I did not see a file list slow down as I have caching on in Server.app 5.1.5



ps. I still use Onyx third part tool for osx and El Cap, as this still does a permissions fix.

I have pointed Apple to this thread for further evidence that this is a real issue. Received nothing but canned responses marking it as a "duplicate". I filed the first report of this bug in NOVEMBER 2015, under 10.11.1 and I find it totally unacceptable that there have been FIVE OS X updates and NINE months gone by and not even so much as an acknowledgement of this serious bug.


Quality control has really suffered since the loss of Steve. RIP Steve. I hope Apple gets their s--t together soon.

I posted my original bugreport to OpenRadar, in case anyone else filing reports wants to link to it etc.

It would be really nice if whoever filed bugreport #19742550 could post to OpenRadar as well, since mine was marked as a duplicate of that bug.
