Super slow shutdown/refusal to shut down?

[AppleFan22]

I've been running OS X El Cap since it came out (public beta, not DP), but recently it has started taking almost three times as long to shut down/restart, or it just refuses to shut down all together.

I've tried resetting PRAM, multiple times, and it worked for a little while, but then it stops shutting down again. We get to the black screen with the loading icon spinning around, which is does (it's not frozen or anything), and then nothing.

I've had to force shut it down to use BootCamp many times now, and I know that that isn't very "healthy" for any computer, so I was wondering if anyone else is having the same problem, and what can be done to fix it?

UPDATE: I've realised the problem is only when OS X El Cap shuts down, not Windows 8.1 Pro. From Windows to OS X is fine, but the opposite is not. Does that change anything?

Running a 5k iMac, and I haven't had that problem, but my mac takes forever to wake up from sleep since updating to El Capitan.

I'm only using a 2 year old MacBook Pro (not retina), but it's had beta Yosemite on it, and shipped with a fine version of Mavericks, so I can't see the problem! It's fine waking up from sleep though. You are you don't have safe sleep on?

I find that usually if my MacBook is taking a short while to shut down I ensure that 'Mail' is definetly not running since it often stops my computer from shutting down.

May just be me though.

Nope, always make sure ALL app are closed before logging off/shutting down/restarting etc. unless I have to force shut down/restart for whatever reason.

I am having the same issue with Shutdown/sleep taking much longer. I also had the same issue in Yosemite. Prior OSX was very fast shutdown and instant Sleep.

I have even tried booting up the computer not logging in and shutting down or sleeping from the login screen and it is still much slower.

Check the other slow shutdown thread for instructions on how to log sleep issues with pmset, then report bugs to apple.

I think I've tried that too, still nothing useful. Urgh.

That was absolutely useless, considering the fact that a) you hadn't even given me a link to the thread, and b) his/her computer DOES actually shut down, and has problems with sleeping. MINE doesn't. It goes to sleep fine, and WON'T shut down.

Ah, OK sorry for not reading properly. Have you checked the shutdown logs -- tried verbose logging?

Annoyingly apple have stopped logging shutdown it its own log file, but you can use the system.log for this. Open console, note the time, insert a couple of markers (icon on toolbar), then immediately restart. On restart you can then check console for everything from the interted markers until you see shutdown: log entry. Then use that to either solve your problem or post a bug to Apple.

Again, that wouldn't really be much help, as the computer doesn't turn off at all. It gets to the black screen with the loading wheel and just stays there for ever and ever and ever and ever.

Yes, but launchd should be logging stuff irrespective of what the GUI is doing, until there is something that causes even launchd to hang, but you can't know it is just because WindowServer etc. is doing something. There isn't anything else you can really do, how are you going to provide feedback to Apple so they know what specific problem you have that most of us don't...

Right, I think I understand you. When/if the Mac shuts down and turns back on again, what sort of thing am I going to be looking for? Or should it all be submitted to Apple? In that case, how do I get the logs into a sendable state i.e. export them to the desktop?
