contacts app is crashing, won't open
I run an imac with HighSierra installed. Until yesterday I never had any problems with my contacts app. But all of a sudden it started crashing. Now it won't even open. When I click to open it I just get a message that it unexpectantly closed. Well, thanks a lot for that! Any suggestions as to what I can do to restore the functionality? I kind of need this app for my daily work! Thank you!
