Can't Log In From Macintosh
Enthusiast - Level 2

I seem to be unable to log into the community forums from a Macintosh - it doesn't matter which browser (I've tried Safari, Firefox, and Chrome).

Even if I'm already logged into Verizon.Com, and even sometimes when it says I'm logged into the forums (after coming from - if I try to post to a forum, one of two things happens:

1. I get a message "my verizon not available," or

2. I get a screen asking me to log into the community forums (even if it says I'm already logged in) - and then, after entering my username and password, it just takes me back to the same login screen.

Note:  When I boot up Window (on the same Macintosh) and bring up either the MS Edge Browser, or Chrome, everything works just fine (which is how I'm posting right now).

Anybody have a clue as to what's going on, and how to fix it?
