oh ok I see, Do I simply just hop on safari and log into Facebook? Are there precautions that I need to take? Note: I got an account disabled on the MacBook about a year ago, but the BM isn't disabled anymore however, I already deleted that FB profile.I would never use Google Chrome on any platform, not even with macOS/iOS/ipadOS, it sends too much data to Google.
But regarding your question related to Facebook/Google Chrome: I don't think Google would exchange data with Facebook, so you will be on the safe side if you use your Mac.
I think I read somewhere that suggests making a new user, I wasn't sure it was a new google account or an overall apple user.
