How to import Display Profile?

[Brize]

I'm looking to use a pre-exisiting Display Profile, but can't find a way to import the .icc file. I've tried dropping the file into /Library/ColorSync/Profiles/Displays and /Library/Application Support/Adobe/Color, to no avail. Either way, it just won't show up as an available profile.

I thought of creating a new profile and copying over the values manually by performing a dummy calibration, but I don't appear to be able to edit the resulting file—or any of the other profiles.

Any thoughts?

I recall checking this through ColorSync Utilty in the Utilities folder... it's been a while since I did this at work on Panther.

/Library/ColorSync/Profiles/Displays

This path is the same as the path on my home Mac for the profile for my display which I added after initial OS installation.

Stupid question: but have you tried rebooting after putting the ICC profile in there?

Not such a stupid question: I did log out, but didn't reboot. I'll try that now.

Still not recognising the profile, I'm afraid. Thanks for the suggestion though, Blue.

By the way, I'm running 10.4.2 on a rev. B Dual 2.0 Power Mac with a 20" ACD.

Have you tried verifying the profile using Profile First Aid in ColorSync Utility? Will it even 'see' it?

Could it also be a permissions thing?

After double-checking, my profiles are in the ColorSync folder in the Library folder at root level, not the Library folder within my account.

No, it won't even 'see' the file. Permissions all seem to be intact…

Yep, I've been dropping the .icc files into the system Library, rather than my user Library.

Strange. I'm afraid I can't offer any more help...

Thanks anyway Blue. I really appreciate your help.

The fact that Profile First Aid won't even recognise it as an ICC profile might say something about the file itself...

Where did you get the file from? Does it have its extension? Does it appear as an ICC icon?

I don't know if this helps or not...

But I did a test. I went into that folder and copied a profile to a new file (test.icc). When I loaded system preferences thereafter (no reboot or login/out or anysuch), the new profile showed up, although it was a duplicate entry with the original name (it was not called "test"). Closing system preferences and deleting it made it go away.

Is the profile you are trying to import a profile for your specific monitor, or another copy of the same model, or another model? Was it made in Tiger or Panther?

Also, are the permissions -rw-r--r--, and is the file ownership set to root:admin?

The file came from another Mac, and was created in 10.4.0. Yep, it has the correct extension, and displays the .icc icon.

Many thanks for the response, mkrishnan.

I replicated your test and achieved exactly the same results.

The profile was taken from a rev. B 20" iMac G5, and was created in 10.4.0. The permissions and ownership are all correct.

Eeep...that explains it. They're tied to the monitor. When I plug an external LCD into my iBook, I don't see the calibrations for the iBook screen as options for the external screen, or vice versa. I think you don't see the calibration because it is not applicable, at least in the software's thinking, to your screen.

Thanks for that—makes sense. In that case, does anybody know of a way to edit the RGB/XYZ values etc. contained within each .icc file? If I could just tweak those, I'd be set.

I believe I heard that all you have to do is change the display type in the icc profile itself. Just locate the icc profile and open it with colorsync.

then just replace that profiles mmod tag data with the mmod tag data from your current display.

Oh yeah, you can edit those numbers the same way. Find the file with finder, option click and "open with > colorsync utility" then it'll show all the values of the file and you can change them. that would probally be easier.

Edit: Easier way, just double click the profile in the "Profiles" menu of colorsync.

That's the problem: I can't seem to modify the mmod tag data. I'm able to highlight the fields, but that's it. Is anyone else able to edit the mmod tags?

Edit: I just tried to edit the tags whilst logged in as root, but that didn't help either.

Try this in Colorsync.

Go to the devices tab, pick the monitor you want to import the profile to, then you should see an option to change the current profile of that device. I hope that helps.

Thanks for your help, Tab. I was able to change the profile through ColorSync>Devices as you suggested, but the profile settings didn't take effect. When I went back into System Preferences and opened the new profile, the values were identical to the default values. Further, when I clicked away from the new profile, it disappeared.

I don't think it's going to play nicely until those mmod tags have been modified to recognise my display, and I'm not sure that's possible. Thanks to all for your help in any event.
