When you log in, please open the Activity Monitor, find the Dock item in the list of processes and double click it. The next bit of data comes from the Activity Monitor. The ~/Library directory can be accessed from the Finder by holding the Option key (or Alt key) and clicking the "Go" menu and then the Library item. The ~/ is a shorthand for your user home directory. This gives a list of all he possible items that might influence the normal operation of the Dock. List of applications that you have set to automatically start when you log in on the dock.List of items in the Login Items in the Users & Groups panel (also sys prefs).List of items in the extensions panel in the system preferences.List of files in ~/Library/LaunchDaemons (if this directory exists).List of files in ~/Library/LaunchAgents (if this directory exists).To figure out what is causing the problem, the following data is needed: This means it is restricted to whatever applications are running when you log in, and any files and settings in your home folder. If the issue is gone, it is only in your account. It might also be something that hooked in to MCX which is a system designed for network administrators to make settings stick on computers. If so, the issue has to do with something you installed and is running as an application or service in the background. Use the preinstalled Apple apps and see if the problem is still there. Make a new account via System Preferences, log out, and log in to the new account. You already commented somewhere that you found the solution in a Chrome extension, but if someone else arrives here with a similar issue but without using Chrome or an extension, this might prove useful.įirst step is to check if this issue is system-wide or bound to your user account.
#Os x moving dock icons series
If your issue is not resolved yet, I can come up with a series of things that might be happening but require some digging. You lift your finger from the key, but Dock (and all your other apps) think you're still holding the key down.

If Sticky Keys has become activated, it's easy to press the command key intending to invoke some keyboard shortcut, and then change your mind. The key behaves as if pressed until you tap it again to unlock it. Tapping a modifier key twice in a row locks it, similar to how Caps Lock works. Note that dragging something to/from the Dock is a mouse action, not a "non-modifier key", and does not release the sticky modifier. The purpose is to facilitate use of the computer by someone who can press only one key at a time. When Sticky Keys is turned on, tapping any of the modifier keys (command, control, shift, option) makes the modifier key "stick", even after you lift your finger from the key, until you press a non-modifier key. This is easy to do if you are playing a game that uses the shift key as a fire button. By default, Sticky Keys is turned on/off by pressing the shift key five times in a row. You might object "I would know if I were holding down the command key." But it's possible you are inadvertently enabling "Sticky Keys". When dragging a document from the Dock, it lets the Dock know you intend to drop it somewhere (such as on an application or into your Finder sidebar) and are not trying to remove it.

When dragging a document to the Dock, it prevents icons already present from "dancing away" from the one you're dragging, making it easier to drop a document onto an app in the Dock. The command key temporarily "locks" the Dock, so that drags to/from the Dock do not affect it. Is it possible you're unwittingly holding down the command key while dragging.
