Dock Icons no longer have any indicator lights to show they are active.
The App Icons do not respond to right clicking.
An open Icon does not appear so, and the application will not shut down via the Dock App Icon.
Mac Pro, OS X Mountain Lion, The Doc working okay on MacBook Pro
You don't have any Parental Controls or such turned on?
Have you tried deleting the dock plist files?
To do so, click on the desktop to make it active, the go to the menu at the top of the screen and select Go then Go to Folder.
Type or copy and paste this in.
~/Library
Then in the window that opens go to the Preferences folder and delete the following file. Before doing so, make a record of how you have your dock set up as it will reset it to the default.
com.apple.dock.plist
Then drag your apps from the Applications folder and and any other folders back into the dock.
Instead of deleting the plist file, you can copy it to the desktop, and if this fix doesn't work, you can just put it back and your dock will be back as it was.
Restart your mac and check if the problem persist.
is your issue fully resolved?
Thanks to you and to parna.
On the path to a cure I shut down the computer and waited until all settled then restarted the computer.
When the sign in window appeared I did so, but then held down the option key which eventually took me to the window of choices.
The amount of broadband allowance used to upgrade both computers and all the relevant applications required by Mountain Lion plus having to redo the upgrade of all the relevant application upgrades due to the AppStore 'timing out' saw over 17GB used,
This hampered (prevented) a reload of Mountain Lion.
I had already tried three (3) shut downs and restarts to no avail.
However, going back to the window showing choices, I chose to restart using OS X 10.8. This was a different way of achieving the restart,
Having said all of that, everything now appears to be as it ought to be, and I thank you for assisting with ways of overcoming the problem.
Another workaround besides restarting the computer which helps me when the issue occures is:
open the terminal and just restart the dock with "killall Dock"
Thank you zeusthevoice, that did the trick!
Great tip - it works! Thanks!
FYI: My problem is that the dock icons gets unresponsive after a longer period of "up-time" for the MBP (mid-2010, 15", version 6,2). I can only get to the different apps by way of the CMD-TAB feature. Untill now I would close all apps and restart MBP.
I am experiencing same problems.
Restart resolves this, but the problem keeps coming back.
Come on Apple, I thought better of you than break such an essential component of the OS !
I have to say, with each upgrade (Lion, Mountain Lion) I am experiencing problems that should have been ironed out years ago.
Why tamper with things that work well ?
Same here, killing the dock process does it, but it keeps coming back
Same here. Started immediately after upgrading to 10.8, not solved in 10.8.1. Killing the dock helps but the problem comes back quickly. Especially the fact that many apps no longer show up in CMD+TAB is very frustrating. I can't recall having encountered such a fundamental bug in Mac OS before.
ive got the same problems as pniederw described. it's kind of annoying to think that this is supposed to be an upgrade from Lion... Thanks for the command though, it works everytime but the problem keeps coming back.
I would love to see this solved - it is a frsutrating little issue. I can run the Killall command as suggested, and that works, but it is the equivalent to a one tiem refresh, something the OS does.
It does not seem like a wide spread issue. Does anybody else run any thiord party tools that may cause this? I run:
DockView - an addin that adds bade icons and preview windows
Default Folder X - An addin that provides more power to the save-as and Open dialogs.
Other than that - I do not see anything that could cause an issue.
