Hi Marilynjk,
We do not get a notification when someone posts on their forum profile, so you would need to post in one of the thread in the forum to get help faster.
Please make sure that you have done all your updates on your Mac. Then please click on this link for information on what to do about loading Issues and Persistent Loading Issues if you still can't load the game in your browser of choice or Opera browser.
