Q: 3. Will the Mini Display Port connector on this cable connect to a Mac Pro's (trash can-style) Thunderbolt 2 port and work with a monitor that has a DisplayPort 1.2 input? (I've read that Thunderbolt 2 and Mini DisplayPort 1.2 are essentially the same.)

A: You can use this cable to connect a Thunderbolt 2 port to a Display port.

Q: 4. Can you Daisychain this to 2 thunderbolt displays?

A: Thunderbolt displays require an Apple Thunderbolt port to work. They work exclusively on a Thunderbolt data signal, not just a video signal. This adapter only convert a video signal to a video signal. The form factor is the same for Thunderbolt 1&2, but the data being sent is much different. This adapter is perfect for using an older Apple Cinema Display that has a Mini DisplayPort, and connecting it to a video card or computer that only has Displayport (such as Nvidia video cards, or HP computers). I am using it for that, and it works perfectly. Hope this helps.
