Photoshop App won't go into iMac Dock
I have a 5k 27" iMac. Mojave 10.14.6.
I've accidentally deleted my Photoshop 2020 app from the dock instead of the 2019 app. I did it by dragging it out the dock and it disappeared with a whoosh and smoke cloud. I then dragged the 2020 app from Finder Apps to the dock but it won't go in. The apps there won't move to allow a space. I can move apps within the Dock so that's ok. Apart from the Apple apps already there I only have PS-LR Classic and Google Earth but it would only be replacing like for like so not a case of the Dock reaching a limit. As an aside, I don't know why PS CC 2019 is in the Dock or Apps as well as 2020.
I've tried the following.
- Apple menu > Force Quit.. Select Finder and relaunch.
- Re-start computer.
3.Turn off computer and restart holding down Shift key until Apple logo shows.
All failed to resolve the issue.
Thanks.
