Sadly not many online casinos are designed to run on Apple Macintosh. Most of them are designed to run on Windows software. But that doesn’t mean that you will not be able to play at online casinos at all. The no-download casinos operate using plug-ins like Flash or Java and these work fine on the Apple Mac. Some online casinos have even begun to offer download Macintosh software. But such they are not too common just yet. If you have a Macintosh that operates using Intel Chips you will be able to emulate a Windows PC and therefore may be able to operate a download casino successfully. Before you decide to play at a casino, contact the customer support to know for sure if they casino works on your Mac and how you can get the casino to operate on your Apple Macintosh.
