Blue screen of Snow Leopard - Display vs Color LCD Profile

Hi everyone.

Just thought I would let those people who are asking why (after installing Snow Leopard), they have a blue-tinted screen, it's because of the new "Display" profile. The original "Color LCD" profile has been replaced with a vile-looking, blue-tinted profile that is just horrible (IMHO). I have taken a screen grab of both profiles details, so you can see for yourself, as some extra settings have been added to the new profile. You will also note that the RGB tone response curve has been changed from a setting of 14 to setting of 2060, which is a pretty huge curve.

This is just one of several backward steps I have noticed in 10.6 and I have already reverted back to 10.5 while things settles down somewhat. I have also saved the Color LCD profile so that I can move it over to Snow Leopard should Apple not correct this washed-out blue/white disaster of a colour profile. Many things need changing before Snow Leopard feels like an upgrade (but talking about why the Firewall is now off by default, over-sized desktop and folder icons, the lack of any preference settings at all in QuickTIme X and other stupidly backward moves will be reserved for other posts). This is the first time in my 17-years of buying Mac's that I have ever reverted back to a previous OS so quickly.

Here is a link to the profiles:

Lot of crap here.

Blue-tinted screen. I don't get it but if it bothers you, change it.
Over-sized icons. Use the slider. That is what it is for, and more.
QuickTime X. You have a choice and even three for that matter.

Backward moves. Then don't advance. Nobody is forcing you use it.

Yes, there is and most of it is coming from your assumption that I am being "forced" to use it.

Blue-tinted screen: if you look around at some of the other posts here and you will see that quite a few people have had this problem, you must be very lucky indeed.

See this post:

Over-sized icons: my point was, why have them set to such an over-sized value from the outset on Snow Leopard? They have never been set to such a large scale on any revision of OS X and I've been using it since it was a beta and Mac's were still shipped with OS 9.2.2!

QuickTime X: my final point with regard to that is, it's very unlike Apple to ship something as part of an OS update that plainly just isn't ready. I am well aware that QuickTime 7 is still there (as an optional install), but I don't see the point in giving the user something that is so incomplete, even if it is only to evaluate, what are we evaluating? There's so little there that no real conclusion can be arrived at other than it shouldn't be included yet, not until it's ready.

I don't see much "crap" in that.

I still have the profile Color LCD. Strange that you lost yours.

Did you try calibrating a new profile before downgrading?

Hi Magnus,

From what I have seen in other posts, there seems to be a glitch when doing a clean install of Snow Leopard on some MacBook Pro's. One topic is saying that MBP's with a display build of 9CC2 will sometimes have the "Display" profile written due to SL not recognizing that build of display. If you just update, the "Color LCD" profile is saved and ported over as it upgrades.

I saved the profile to load up and compare settings and they are very different. I have been able to save the Color LCD profile and load it up in SL and it works a perfectly. I haven't tried a calibration yet.

That's what I'm seeing with my MacBook Pro also. I first installed over 10.5.8 and the screen was washed out and blue tinted. Selecting the "Color LCD" profile looked okay, but it doesn't seem to hold it on my login page, and my other user accounts have to choose it also. Next I tried erasing the HD and did a fresh install of 10.6, and that didn't even install the "Color LCD" profile! Only the crappy looking "Display" profile.

I tried to do the "expert" calibration, and it was still blue.

At the moment I'm restored back to 10.5.8 & I guess I'll call Apple FWIW.

SL uses a gamma of 2.2, which has been my preference forever…but I guess not for everyone 🙂

You can change it back to the old default of 1.8 by going to Displays/Color click Calibrate->Continue (no expert mode necessary) Choose Gamma 1.8, Continue, Native WhitePoint, Continue, Name the new profile maybe Retro 1.8? Continue and Done.

The display should look like what you're used to. If not you can delete the new profile and try again with different settings.

The default Color LCD profile of my MBP is very brown looking. All the other profiles do have more a bluish hue to them. But blue is my favorite color and I use Apple RGB, or Adobe RGB, depending on my mood.

I could, but I wasn't sure if it would be automatically deleted, being that the rules are quite strict here.

*_I posted this in the other thread too, but in case some of you weren't watching that one, I'll post it here too*._

Regarding the color profile/blue tint issue, here's what I've figured out is the problem with Snow Leopard, and the LCD panel model 9cc2 that I have.

Knowing from the ColorSync profile on my MacBook Pro 13" that the display make is 610, and the model is 9cc2, I went hunting in the System Folder.

If you go into the folders: "System", "Displays", "Overrides", "DisplayVendorID-610", and scroll down through the list. You'll notice that a DisplayProductID is MISSING for 9cc2!
Apparently Apple left 9cc2 out of displays in Snow Leopard.

Soooooo, what I did as a workaround to fix it is went to my backup from Leopard, and copied "DisplayProductID-9cc2" into the folder where it should be. Then copied the "Color LCD" profile from the backup also to "Library", "ColorSync", "Displays". I restarted, and my display looks great again, and I'm running 10.6!

I have an open case with Apple regarding the color profile/blue tint issue and I'm going to let them know what I found when I get a call back from the level 2 tech.
