Hi there. My MacBook crashed today suddenly, and when it came back on most dock icons were missing, I was able to get them back by removing and re-adding to the dock but the finder icon as you all know can't be removed and re-added. I've restarted and did an disk repair and even tried changing the icon, but I can't seem to be able to do that anymore so that must be thing of the past. I have no idea what to do, I've searched and forum posts about this happening Yosemite but have yet to find a working solution and am posting her as a last resort. Thanks in advance to anyone that can help! EDIT: Resolved. Anyone else with this issue: Run this in Terminal: defaults delete com.apple.dock killall Dock Then restart even if it looks like nothing happened.
