In wonder what that could have done for the profile building itself? I think
that only serve the purpose of selecting the 'default' CMM at profile
creation time. You know for the header?

Can't the verification be done strictly on the basis of the calculated tags?
Convert Device to PCS and then use the "looked-up" PCS numbers to calculate
their way back to Device and compare. I don't see why go through a CMM to do
that, Roberto?

You mean most CMS packages would you their own built-in CMM for profile
building purposes? I'm not sure any CMM is used at that point.

It the same application code ported from one plattform to another. I
personally don't see how the PC version of ProfileMakerPro can produce
different profiles as the MacOSX version of ProfileMakerPro. But I suspect
you're suspecting that they do?

That is my opinio.

There, I'm not 100% sure. Windows XP and MacOSX should yield indentical
results as far as rendering to the screen goes IF you have the same monitor
connected to both systems and IF you're using the exact same monitor
profiling package with the SAME instrument.
At least, it should be very similar in Photoshop PC and Mac.
