So I have a MBP with one Thunderbolt port. The issue is that my Apple 27" monitor (the model that was sold right before the Thunderbolt monitor was released) needs the thunderbolt port. And, my external SSD drive also needs that port. Is there a splitter or something similar so that I can plug in both devices at the same time? Or is there a way to have the monitor use a different port than the thunderbolt port with some kind of plug adapter? Thanks.
