So I have a new E-M5 and I christened an SD card in it and noticed that when I plugged it into the iMac it said "NO NAME". So I gave it a name while in the iMac. I gave it some sort of Oly OM-D name or something like that. Everything was fine and I ejected the card. Then I reformatted it before using it again for other images and the next time I plugged the SD card into the iMac, it was back to "NO NAME." Does formatting not give the card a camera specific name like my Nikons? And if it does, why doesn't my iMac acknowledge it?
