My wife's MacBook Pro 2010 model was upgraded with a new SSD HD and the computer repairman also installed Catalina OS on the new HD. He copied all of her docs, pictures, etc. to a portable HD as well. I have located the Bookmarksplist file via Finder/Go to Folder/safari/library. I do not know how to get Safari to recognize her old bookmarks in the new operating system. I am at a loss to make any changes as she is afraid I'm going to mess up the computer and lose things. Being a Windows guy since its inception, I don't know the Mac way of getting this to work properly. Any help would be most appreciated. Thank you.
