Just a quick warning about the latest OS-X upgrade: I automatically downloaded and installed 10.9.3 from Apple and... no more eGPU. I fiddled with it for a while (not being that tech savvy) and gave up. I ended up restoring from a Time Machine backup, thereby stepping back to 10.9.2. As an aside, I clicked on "details" and noticed that 10.9.3 apparently includes changes intended to accommodate 4G monitors. I assume those changes are getting in the way of the quick kext fix for which we were all so grateful. I look forward to hearing from our resident wizards as to how to make everything work with 10.9.3.
