I bought a MacBook Pro after my XP laptop was stolen, and found that I enjoyed using it for PhotoShop (I was away from home for a month - couldn't go a whole month without editing an image!). So I replaced my main PhotoShop machine (which was perfectly acceptable) with a Mac Pro so I had the same environment. I like it.

I calibrate both my laptop and the Mac Pro using a Gretag Macbeth Eye One Display II. On the laptop I do a software calibration using the Gretag Macbeth software - works fine. On the Mac Pro I am running Eizo CG monitors, so I use Eizo's Colour Navigator (which works very well with Gretag Macbeth hardware) - that does an excellent job. The coolest part about Colour Navigator is that it works at the hardware level, calibrating the Eizo hardware so that it becomes, effectively, a "perfect" display.

I've had no problems with failure to save calibrations with either setup.

Oh, and I tell PhotoShop to print with PhotoShop controlling the colours and using a profile for the printer/paper combination - I don't use ColorSync there, either.

BTW: bear in mind that the printout is supposed to match the screen only when viewed under particular lighting conditions (D65, I think it's called) - something like a match for a sunny day. Normal indoor lighting will make the print look dull and lifeless.
