Overall, with a mid-range graphic card, you can manage for about 500 $.įirst, with OS X Yosemite, type this command and reboot, it’s important to load modified kext. The ViDock enclosure can be replaced by a BPlus PE4L, it’s cheaper and as effective. ![]() ![]() AMD cards work, but with big graphic bugs, so I’d advise you not to use it for the moment.Īttention : use only a Kepler or a Fermi NVIDIA card, not a Maxwell card (GTX 750 or GTX 970). For everyday use, I installed a fanless GeForce GT610 (low cost) only to manage screens. In my case, I use a ViDock 3 enclosure (an ExpressCard enclosure, already used on my old MacBook Pro), a Sonnet Thunderbolt to ExpressCard adapter (the Pro version, PCI-Express 2.0 compatible) and a Thunderbolt cable.Ĭoncerning the graphic card, any recent NVIDIA model – I tested a GeForce GTX 260 from Zotac, a GeForce GT120 from Apple and a Quadro K5000 for Mac – works. If you use OS X Yosemite and NVIDIA Maxwell cards, click here. ![]() This is not easy and there are a few issues, but it works pretty well. This is the holy grail for some: it is possible to use a Thunderbolt graphic card on a Mac. Today, a tutorial: how to use a Thunderbolt graphic card on Mac.
