Pages and Numbers have generic app icon in Dock

Question

I have a MacBook Pro 13" Unibody Early 2011 running macOS 10.13.6 (the latest it will support). I wanted to replace the HDD with a 256GB SSD so I did a fresh install to the SSD in an enclosure then ran Migration Assistant.

As far as I can see everything is working OK, but there are couple of anomalies . The Dock icons for Pages 8.1 and Numbers 6.1 seem to be some generic app icon.

I deleted the Dock entries and ran from Launchpad, but the icons remain. In Finder the icons in Applications look OK although not in Launchpad.

I deleted com.apple.dock.plist and ran the command killall -KILL Dock

How can I restore the correct icons?

Answer 1

1) In a Finder window Go to Applications.

2) Locate the application's icon and do a Get Info.

3) In the top left corner of the Get Info window the correct non-generic application icon should be displayed.

4) Select that icon using the mouse.

5) Do an Edit->Copy on the icon in the top left corner of the window.

6) Do an Edit->Paste on the icon in the top left corner of the window.

7) You may have to provide an administrator password.

Answer 2

Ther should be a file in ~/Library/Application\ Support/Dock/either called desktoppicture.db or with a garbled name .db. You can try to delete that file with rm ~/Library/Application\ Support/Dock/*.db and afterwards restart the dock with killall Dock. This should fix the issue, as the com.apple.dock.plist does not contain all the launchpad settings.
