The cards aren't completely independent, and can't just be plugged into any motherboard with a PCI-Express 2.0 x4/x16 slot. It requires a special header that's used for timing, and low-level system interface, and optionally, an end-to-end DisplayPort (if you want to relay display from your graphics card through the common Thunderbolt pipe). A list of compatible motherboards can be found on the product page.
Thunderbolt, as the spec is designed now, will never ever ever work on a stand alone PCI-E card (without a special motherboard).
Unless the spec changes, the answer for an oMP will always be no.
And now the latest ban that you can't download a fresh copy of your OS if installer was made before Feb 2016
There have been posts about it on here but for some reason they keep getting deleted or moved.I just confirmed that two of my archived installer images (Yosemite and El Cap) I made before Feb 2016 can no longer be used to make USB OS X installers . I thought they became corrupt (which is a very rare circumstance as I keep immaculate archives .) Now I am beginning to think Apple is playing games with us . Should we make a new thread with this issue ?
What? When did this happen? I downloaded Yosemite and El Capitan installers from the App Store just a few days ago.
