Dock using 100% CPU

[WesCole]

All of a sudden, the dock process on my MacBook Pro is taking up exactly 100% of my CPU constantly. Anyone else have this happen? I heard it may be a problem with the newest build of parallels, but I haven't noticed it until right after I installed today's Snow Leopard update.

A restart failed to fix the issue, too.

Thanks for any help.


Edit:

After some testing, it is the new build of Parallels (not sure if it is conflicting with the new SL update, though). The only solution I have found is to delete the dock plist and manually change the dock back to my liking. Kind of a pain.

I hope Parallels gets this fixed quickly, since I need to use Windows on my Mac for school and work.

I'm having the same issue.

Yup so am I.

It's a parallels bug.

Workaround is to remove your windows applications folder from the dock (in the parallels vm configuration, applications tab) - see here:

Glad I found this thread! I was pulling my hair out, but your solution worked for me as well.

I never would have suspected Parallels, since the dock was running at 100% even when Parallels is not running...

I just started a post on how to undo 10.6.8 as I thought that was it. My MBP always ran cool until yesterday now my fan is screaming at 5000 rpm's and the CPU is staying around 190F, and thats with it sitting there. Anyone else's heat go up by 60deg F?

I LOVE THIS PLACE!!! I did the fix posted above and my fan is at 1999 and my CPU is back in the 120F range

And I thought it was 10.6.8 that caused it.

[dealmaker]

Thanks guys - just saved me throwing the thing out of the window!

parallels should have issued a patch or an update/e-mail to all users - bit naughty!

Parallels build 12092 is out now, which claims to fix this problem.

Parallels fixed with latest update

I was having the same issues today with 99%cpu usage and I did an update with Parallels about an hour ago and it fixed it. Thanks to everyone with their comments and help with this issue. I was ready to take my laptop to Apple.

Dock using 100% cpu

This happens with Vmware Fusion 4.1.1 as well (very recent upgrade) - well I assume that is the reason my Macbook pro was using over 500% cpu. ..... yes how come with *only* four CPUs (#

Incidentally why when posting a reply did I have to type the subject? A bug?

OS X 10.7.2
2.3 GHz Intel Core i7

Where does it show 500% CPU usage? Have you looked at Activity Monitor yet?
And as you have an i7 in your MBP, you have FOUR cores with TWO threads per core, thus you have EIGHT threads as a whole, which show up as EIGHT cores.

Do you mean the TITLE field?

not using parallels

I see that a lot of you having the issue that DOCK is killing my CPU on my MBAir.

Most of the solutions are re Parallels ... but I do not have Parallels on my machine.

Are there any other solutions for getting my CPU back in shape?

I had this issue on my MBA and I just quit the dock process, it then automatically restarted using the normal 0 or 1 percent. I too don't have parallels or any VM software on my Air.

Amazing. I have an expired trial of Parallels 7 installed on Lion 10.7.3 and have this problem! Thanks for the tip! It still works.
