Q: Can I use this to connect my canon 5d mk iii to my macbook pro? if not does anyone know what I can use?

Well! great question. This will fit on the Canon 5d, but the end that should go to macbook may not fit, if your mac-book has only type c on most latest vesions of macbook pro, in that case i think the simplest way is to use a sdhc card reader to download and then insert card on macbook pro.
