Im not sure then...This is why so confusing....I attempted to connnect the mac pro book to external monitor and as stated the colors when printed were way off....However I saved the file to a CF card put to PC and then output that to a printer and Same pic came out fine?? It makes no real sense to me?
Could be that the ICC (color calibration information) is not being correctly interpreted on your Mac for some reason.
The ICC information is embedded in your picture by the device (scanner or camera) that produced the image. It is used to compare with the profiles of other devices to attempt to make sure that the image seen on your screen, printed on your printer, scanned by your scanner, and so on, all look the same.
It's possible that OS X is somehow interpreting that information improperly. And, that's not such a far fetched idea.
I've got a scanner that I use to scan in my pictures. And, in OS X, the pictures look fine. But, when I print them from OS X, they come out scrambled like a poor television picture (like if you try to watch a scrambled cable channel).
If I print them in Windows, they look fine.
If I remove the ICC profile from them, OS X will print them properly, but their colors will be off.
Interestingly, these same images print just fine from OS 10.3.9. I've had this issue with the pictures only in OS 10.4.0 and later (I first noticed the bug in the PowerPC 10.4.0).
And, the issue persists on the new Mac Pro I have with the Intel 10.4.10 release on it.
I've notified Apple, and over time it's gotten slightly better. In 10.4.0, the images would be scrambled on the screen as well. But, after 10 revisions to 10.4, they've finally gotten it to where it looks fine on the screen but still prints scrambled.
At this point, they probably aren't even working on fixing it anymore. Who knows.
I say send a report to Apple, and see what happens.
