A Mac User's Best Friend!/PLEASE READ BEFORE POSTING ANY NEW PROBLEM THREADS!!!!!!

I have just updated my computer from a PC to a Mac. I have managed to download my Sims 4 games no problem, but when I try to download my Sims 3 games it gives me the option to download and then goes to preparing download, but that is as far as it gets as then after about 10 mins or so it comes up with a download error saying that it has tried to download varies times but was unable to. I have spoken to EA who were no help at all and just said that it was a known problem that they were working on! Has anyone else had this problem and know of a solution?
