Apple ID
When I try to log into Facebook or REALTOR.ca or other apps, my Apple ID is a gmail and I no longer use this. Of course any new password I create does not match because my real ID does not appear. I have tried resetting my password many times and am running out of choices that I can remember. How do I get rid of that old Apple ID? I am not very savvy about this stuff so please be kind! This happened as soon as I updated on with my Mac.
