I have a few older pro laptops and the newer a1229 running El Cap I thought might try to drag into modern times. So this: http://www.ebay.co.uk/itm/271969145199?_trksid=p2060353.m1438.l2649&ssPageName=STRK:MEBIDX:IT with this method: https://www.tonymacx86.com/threads/...drivers-caldigit-lacie-oyen.77864/#post554335 I'm tempted to order the card and try as it is cheap.
