So I formatted 4 out 5 of my SD cards on my iMac and now when I put them in my Mavic it says "SD card slot empty". The 5th SD card was not formatted on my iMac so I know its not the Mavic its the other SD cards. I know this might be a topic more suited for a Mac forum but I figured it wouldn't hurt to ask the fellas. Any input would be greatly appreciated
