Photoshop misssing in "open with" menu for illustrator file

[Lunnson]

I am using Mac High Sierra and after updating to CC 2018 from 2017 Photoshop is missing in the open with menu when right clicking on an .ai file. I tried uninstalling Photoshop and Illustrator then installed them again. Still same problem... Is anyone else experiencing this? How do I get this back? Note: I also have this same discussion in the illustrator forum.
