MacBook Pro did not shut down (hang)...

Since uninstalling Kaspersky Anti Virus for Mac 2011 (a couple of weeks ago), the failed shutdown problem did completely disappear and did not re-appear on my MBP. Two weeks ago, Kaspersky was so kind to allow me a full refund. Since then, I purchased and installed another anti-virus app (Intego Virusbarrier) and so far no new problems re failed shutdowns have occurred on my MBP.

For me the problem is still open.😠

My iMac i7 still does not turn off after a few days of use and related stops. But if I turn it on, open some programs (Mail, Safari, Xcode) and in a few minutes I try to turn it off, the shutdown is ok.

I repeat: the problem is still open!

No issues with shutdown/restart since Monday, August 29th.

Today I turned off my MBP after 6 days 19:57. Everything went well, even all the open apps have been reactivated in a few seconds ! (XCode included)

I got to thinking that in my iMAC, instead, there is an application too many... I will try to figure out which.

Hi all

in my case the problem is MS Outlook 2011. As soon as I start outlook during a session the shutdown will hang indefinitely. I tried "cmd-q" and force quit before shutdown but this didn't change a thing. As long as I don't use Outlook the shutdown works just fine.

After reading this blog, I swiched Kapersky Anti-virus off and uninstalled it by going to applications in finder, and moving it to trash. i swich off the computer and it worked. No more hanging when I shut down. I was told that there was no point to me having Kapersky on my MacBook pro by the manager in the Aberdeen apple store anyway. It was deactivated but still switched.

I also got the computer to not restart progammes when switching it off so that too maybe helped.

alright, i'm having this problem and i've had it since installing Lion. I've reset the PRAM and SMC, each a couple times. The only login items I'm using are ScrollReverser and MicrosoftMouseHelper.

any ideas? could a bad PRAM battery be the cause? do Nehalem Mac Pro's have PRAM batteries?

i ask about the PRAM battery because I was trying to copy a 3GB file today to a drive where I know I had 144GB free and it said there wasn't enough space.

thoughts?

Same issue: https://discussions.apple.com/thread/3732581?answerId=17588109022#17588109022

Hi everyone. I have a Macbook Pro 2008, 15" screen, aluminum body style.

Since installing Lion, my freakin Macbook now hangs regularly - albeit inconsistently - at shutdown.

Grey screen, little whiz wheel...ad aeternum.

I thought I'd add my voice - to reduce the probability this will just be blown off as a 'isolated problem'.

Respects to all

I have a MBA, running under OS 10.7.3. I had the same issue with not shutting down properly, always having to do a hard powering off.

I finally was able to figure out that the issue is somehow related to wifi. If I turn off wifi, then my MBA will shut down and restart properly. No idea why.

This is a workaround, but not a solution to the problem. If anyone has more info, please post!

Thanks,

Karyn

i just wiped everything and installed Lion & all the other applications fresh. all is well now.

same problem.

mbp 15".

Had the problem in Snow Leopard, and now, after hoping that installing Lion would by some miracle fix it, I have the same problem in Lion.

I honestly cannot believe that Apple is not responding to this thread at all. This problem is EVERYWHERE on their machines...

No info in verbose boot.

reset VRAM PRAM.. bla bla bla.

Do all of you have stock RAM installed? in my case I upgraded outside the apple store. I was wondering if this might be memory related.

this post should have just said "ditto"

arrrrgh when you pay this much money for a machine and you moved from PC recently, it is REALLY REALLY REALLY very dissapointing.

Update from my side. I had a trial version of kapersky antivirus (long inactive an outdated) installed and found some indications that this might cause the hanging shutdown. Removing KAV by deleting it in the applications folder didn't solve the problem but since I did a proper uninstall by using the provided routine my mac shuts down just fine.

I've upgraded my MBP from 4GB to 8GB w/ memory from crucial.com

Since posting my fix months ago, I still have no shutdown/reboot issues.
