I think I know why, roblox ultimate extension has a lot of glitches, try disabling that, adblock plus, or siggy one at a time and try logging in. It is possible that it does not recognize your login because of the extensions. Ik you said checking on firefox and safari may prove this. But not ALOT of people use it, so there is not as many complaints. I do not really know what you mean; but I am guessing your meaning you looked it up online. If you havn't, try disabling them one at a time, try logging in, and if it does not work re-enable it because that is not the one. It also could be because of the MacBook air, I dont know for sure, but I believe MacBooks used a different way to detect someone logging in. Try logging in on a tablet or smartphone. If this does not work, i do not know what to say.
