Why is the "assign to specific desktop" option now missing?

I'm running Maverick on a brand new rMBP, and suddenly I can't assign an app to a specific desktop anymore!


The option used to be there in the dock, but now it's just gone... for all apps.


I have a second display connected, and working perfectly, just like I always do.


Why is that? How can I fix it?


Thank you!

MacBook Pro with Retina display, OS X Mavericks (10.9.5), null

Had the same problem. Turns out I didn't have enough desktops open. When one on each monitor, didn't have the option but as soon as I added a 3rd, option reappeared.

Thank you naarus!


Didn't have time to try Eric Root's solution yet, but in the mean time, the option came back by magic... and I realize I had just added an extra desktop (a third "space", since I'm usually working with two.

Then this morning, the option had disappeared again, but I remember I had closed my third empty desktop. I went back and added an extra desktop in mission control (not related to my second display, just an extra "space", on the "right", after the two "spaces" I already had.) and the option "Desktop on Display 2" came back!


Don't know why, but it works!

Try doing a Dock restart using the following Terminal command:


killall Dock


Log out/in and test. If that doesnt work, you need to look in your user Library/Applications Support/Dock for the .db. Use the Finder “Go To Folder” command. Enter ~/Library/Applications Support/Dock. Move the .db to your desktop.


Then try a dock reset.


Applications/Utilities/Terminal enter the command


killall Dock


Log out/in test. If it works okay, delete the .db from the desktop.

If the Dock is the same, return the .db to where you got them from, overwriting the newer ones.
