Endless spinning wheel on shut down

Rolf: Do you have Parallels installed?

Yes, but not recently. I think for more than a year and it was always ok, had no problems.

Rolf: I suspect that Parallels does cause this particular problem.

Could you try to temporally uninstall Parallels (using the Parallels Uninstaller so it removes all resident drivers, rather than just removing it from the Applications folder) and report if that fixes the problems?

Cheers!

Jacob,

Did you sent your Mac to the Apple Store Genius Bar? They may be able to help, I suspect that your problem might be with the EFI (firmware), as there are no hardware indicators that point to a problem.

As I mentioned earlier, I'm experiencing the same problem a Macbook Pro 13' (2010 model). I though it was being caused by Parallels, but never got to uninstall it (I use it regularly). Sad to see this is not the case.

I also updtaed to Lion and the exact same problem is there.

i have the same problem, however , with my iMac 27, the problem of the endless spinning wheel is both

-impredictable. sometimes it shuts down normally , sometimes it doesn't

-appeared after the upgrade to Lion

As a result i am forced to shut down the system by pressing the power on/off switch.

Overall i notice that the system is much slower than before the upgrade

Same here just happened to me... Just 2 days after upgrading to Lion. I don't know what could have caused this issue I was just browsing the web in Safari and nothing else... Hopefully Apple will adress these issues after the Mac OS X 10.7.1 update.

I would suggest filling a bug report to Apple via:

http://www.apple.com/feedback/macosx.html

Maybe by filling Apple's bug report logs they might be apble to concentrate on this issue...

Im my case this happened starting before installing Lion, so I don't think it's a Lion problem.

It might be a problem with some installed software. Maybe we could check what installed software have the four of us in common.

vea1083, pfattal: Do you remember any recent piece of software that you installed before this issue started happening? You can check all your installed software running the application System Information, in the 'Applications' tab.

Do you all guys have LittleSnitch and/or Soundflower installed?

The only software that I have installed in my Mac is OpenOffice.org, iLife '09, OnyX, AppCleaner, MS Messenger for Mac, Flash Player 10.3, and Burn. All of these have been isntalled since day one. I also did a clean install. I rebooted my computer and after doing a second shutdown my Mac turned off normally. I hope this is a one time issue...

I don't have those app...

The only piece of software that I have also installed is MS Messenger for Mac (besides iLife and Flash Player, but I don't think those would be problematic on shutdown).

Maybe I'm wrong and is a special hardware/software configuration that triggers the problem...

After some additional trial and error (booting up, opening and closing an application, trying to reboot) I found that the culprit was Photoshop CS 5.1. Whenever I did not run PS, the system rebooted normally, but when I started and closed PS, the system would hang a shutdown spinning wheel screen.

With this information I found this other thread where some other people experienced the same problem:

Some people say it's related to Kaspersky antivirus, and indeed I have it installed on my system. Do you guys have (or have had) Kapersky installed on your system?

I'm investigation on a solution that doesn't involve uninstalling Kapersky, will post back if I manage to fix it.

my system was working perfectly well before i did the upgrade to Lion.

i have a lot of software existing before the upgrade including soundflower, Parallel 6 for Mac etc. etc.

I also have installed a trial version of Kaspersky who was a complimentary 3 month version delivered when i purchased Parallel 6 for Mac. I am not using actively Parallel. The only things i did after the upgrade of the OS were:

1. to dowload an update of Java .. required by an application program
2. to dowload the update version of Parallel as advised by the website of Parallel to have it working under Lion. it was not running after the upgarde to Lion and even after the upgrade of Parallel itself. after a small change in a parameter. Parallel is now ok although .. extremely slow

The spining wheel that i am referring to is when i shut down. Sometimes the shut down process is normal. Sometimes it is not. i suspect that there is somewhere an application that is not shutting down properly and preventing the system to shut down.

Unfortunately i came to the Apple world lately. i am still an active windows user and i am far better at solving microsoft problems than Mac.

My main source of problems with windows has always been AntiVirus programs. May be we should investigate in this direction. I will try to remove Kaspersky and i will keep you posted

I just removed the Kaspersky Anti Virus and tried a shut down.

The endless spinning wheel is still here haunting us.
