I decided to use my Mac Book Pro retina as the main machine for image processing. However, I will use my Eizo 24" that is hardware calibrated. I have a few questions to the experts here:

1) What do I need to bear in mind when calibrating the Eizo. I downloaded the latest Eizo software that works on the OS (not the very new version but the one before that)? I want to make sure that calibrating the Eizo does not totally screw up the display of the Mac Book Pro?

2) Can I also calibrate the display of the Mac Book Pro?

3) Could I ahve two external monitors?

4) And finally, for my Spider 2 there does not seem to be a driver that works on the newest version of OS X. Any recommendations for a replacement?
