External Editors unavailable using catalog on an external drive
I have one of my catalogs on an external drive and when I try to access an external editor including Photoshop, all of the editors are greyed out / unavailable. When I access catalogs on the MacBook main drive they are all active. Is there anyway to direct the catalog on the external drive to access the applications on the main drive. I have Mac OS High Sierra on a MacBook Pro.
Thanks
