Correct icon not showing in the dock

Had the same issue (with me it was Acrobat). Called apple support and the connected remotely so they could see exactly what I was talking about.

Solved the issue by deleting ALL the content in the "caches" folder, inside of "Library". You may have to delete the contents a couple of times.

Then shut down completely and unplug power chord. Leave it unplugged for 20 seconds, then plug back in and restart the system... immediately hold the option+command+r+p keys for 20 seconds then let go. Apple image should show up and the system will restart. Launch the application in question and the right icon should show up in the dock.

Hope this helps everyone.

Cheers.

Same issue here just started in save boot and then in normal again and issue was resolved

These steps worked for me. I just did it today!

i'm having the same issue with several icons. Even the Apple Store icon..

Hello !

See this article macOS Sierra: Create custom icons for files or folders

what does this mean....what did you do to fix the generic icon. Please explain. Thanks.

Same here, safe mode reboot was the only one that worked for me, as well.

Booting into Safe Mode and restarting also worked for me! 🙂

Helpful!!!

I was annoying by empty-icon situation for a long time, thanks for your reply, really really help!!

The answer from Eric Root is right, booted into the safe mode and restart !!

I had this problem too- I just removed the app from the dock, went to Finder > Applications > and dragged it into the dock. Simple solution for the problem for me, hope it works!

Booting into safe mode and restarting seems to have solved it for me after upgrade to High Sierra.

Worked, but required a restart

Did it work to not only rid you of the generic icons but did it prevent their recurrence?
