- That is truly too bad as you lose the benefits of investment of the Eizo. Now your video board is limited and you no longer can output 256 gray levels because the X-Rite software necessarily calibrates the video board and reduces it to target (while the Eizo stays unaffected). I would pursue that or revert back to an earlier OSX if that investment is important to you. Many of the production computers at Cone Editions Press are still on OS X 10.4.7 because it is the last operating system by Apple that does not interfere with images that are not color managed..
Having said all that, your brightness is significantly too high. For print work, you need to be no higher than 85 cd/m2. You are trying to imitate light reflecting off paper - so your brightness must "reflect" that - no pun intended. 120 is more appropriate for calibrating to the web or video... Likewise your white point at D75 is significantly blue... I would not consider your system to be calibrated to print. So it may not surprise me that your prints are coming out "too dark" to your reference point (your display). I think that you should find some way to calibrate this display using Navigator so that you can revert your video board back to null and set your display to the parameters of Piezography output. According to Eizo they believe that they have some compatibility with Mavericks: http://www.eizo.com/global/support/compatibility/os_mavericks/index.html
It is worth a phone call to them.
You can check by running a Calibration Mode test print of inkseparation file. But - I do not think your issue is with misplaced inks as you would probably be seeing posterization.
You can convert from ProPhoto to AdobeRGB 1998 quite easily.
We can look at your linearization if you like - by printing a 21 step strip test target (you will find them in the QTR folder in applications. GO overprint it and send to us at:

If you are linear and not too dark - then it confirms the display or your workflow...
You seem to be certain that you are following the workflow...but you may wish to include some screenshots with the print out when you send the 21 step to us.
