As soon as I got it I re formated it on my mac. Put it in my camera and it wanted to re format it agian, so I said, whatever go ahead. All went smooth. Have used it in two different cameras. All pictures easily downloaded onto the mac no problems at all. Patriot has been making memory for a long time so they are a good company from that standpoint. They make mostly computer desktop and laptop memory. Rebate was nice too.
