Can't drag, drop, or move icons from dock
The issue exactly is that I can no longer move icons to the dock, remove them from the dock, reorder them, or delete them. The context menu still works fine, I just can't drag and drop. Furthermore, if I attempt to drag and drop from a stack, it reads the action as if I am trying to open the file.
I'm running Yosemite 10.10.1
Things I've tried so far:
- Repair disk permissions
- Repair ACL permissions
- Rebuild directories
- Relaunch dock
- Reset dock to defaults
- Rebooting/logging out (both fix the problem temporarily, however it returns within an hour of regular use)
- Trying to hunt down any extensions that might be causing issues...can't find anything (problem persists in guest account as well)
- Rebuild and repair kexts
- Cleaned out all caches
- Reinstalled OS X
- Wiped disk and performed clean install.
I don't have anything installed that does any low level modifications (no third party antivirus or tweaking/tune up tools). For the life of me I can't figure this one out and it's really getting annoying to not be able to use my dock.
