Launching Contacts in iMac failed.
Specs:
iMac
21.5 inch Built in 2010
Processor: 3.06 Ghz Intel Core i3 64-bit
Memory: 4GB (2x2GB)1333 16GB MHz DDR3
OS: HighSierra/10.13.6
Problem: On this OS, I never used Contacts. When I open it recently it failed with messages: re-open etc. In System/Library there is no file. How do I reset or re-install or repair?
I use Contacts frequently on my MacBookAir instead. In this System/Library there is also no file because I intended to copy from MBA > iMac. I don't use iCloud on iMac.
Thanks.
iMac 21.5″, OS X 10.11
