On new iMacs it does not really work

I love Pirates! I have played almost every version since C-64 days. I bought this version just to find that on new iMacs, as soon as you get to a town, the screen flickers and basically the game becomes impossible to play. I have been hoping for a patch that will fix this issue but nothing… it is a shame, it is a great game but as it is, most people won’t be able to play it on a Mac...
