The icon previews in finder are not working for me when in column view. I just get the generic file type icon, rather than the preview. When I switch to cover flow, I can see the proper icon preview, just not in column view. The strange thing is, in another account on my mac the icon previews are working. I think this has been a problem since updating to Sierra, but I am not 100% sure on that. I'm currently on 10.12.4. I have tried finding a solution to this for a while, but I am at a loss. Does anyone here have any ideas?
