App Store appears under my wife’s Apple ID on my computer
Hello. I am perform updates on my iMac, but App Store (2.2.1) will not let me because the apple ID is under my wife’s email. I cannot delete her ID to replace with mine. This is my personal computer, any changes require my password. Can anyone help? I'm running on macOS Sierra 10.12.6.
Thank you
iMac with Retina 5K display, macOS Sierra (10.12.6)
