This morning I'm trying to work on my iMac. I keep getting the spinning the beach ball but think nothing of it. Then I notice that Google looks different. It has all these " marks all over the screen. Google on my iPhone, ipads, and MBP all looks good. Only on my iMac does it have the " marks all over it. I can't type because it just hangs and the beach ball spins and spins. I've run ClamXav twice now and each time it came up clean. I'm running Yosemite and everything is up to date. I've attached a pic of what Google looks like for me. Help?
