Separate from the BSOD (Blue Screen Of Death – it’s generally a Windows term, if you’re somehow unaware…) that some folks experienced after upgrading to Leopard, there’s word of a new bluish, or greenish tint that’s occurring on some user’s screens. Up until now I’ve been familiar with the bluish tint that results from Fast User Switching, but the symptoms I’ve heard of from Leopard are much different.

A friend’s MacBook Pro seemed to progressively get worse as the operating system’s uptime increases. Over that time, the tint to his screen got greener and greener – similar to the way an old CRT would look when it lost one of its color channels. A reboot fixed the issue, but it wasn’t a one time thing – nor does it seem to be predictable.

There doesn’t seem to be much in the way of similar occurrences found around the internet, thus, little else to point you toward at this time. If you’ve experienced this issue, we’d love to hear about your experience – what happened leading up to the tinting? How many times has it happened? Is there any rhyme or reason to when it occurs? Or maybe my friend’s MacBook Pro is just going south…Help us shed some light on this problem!

    I have noticed that my Macbook Pro will sometimes have a strong tint to it when it wakes from sleep and I have plugged in the cinema display before I woke it up. I am not sure if the tint is green or orange, but I know it is definitely a lot warmer. The solution for me is to just open up the displays system preference pane, this causes it to reload the color settings and it jumps back to the settings I calibrated.

  2. I have Leopard installed on my G4 1.42 iBook and will leave it running for over 24 hours at a time and have never had any tinting start to happen for leaving it running long periods of time. Almost seems like a MacBook Pro issue – if so I’m sure Apple will release some kind of update for the problem as they usually do.

  3. Perhaps this a corruption of the color calibration profile? I would suggest deleting the profile and also maybe deleting the Displays pref pane’s preference file (if that makes sense!).

  4. some user’s screens

    So you mean only one user with multiple screens?
    (Sorry, but after 3 helpful, substantive comments I thought it was time for a nitpicking one.)

  5. In Tiger the ‘bluish tint that results from fast user switching’ is a bug to do with permissions on display profiles.

    What’s happening is that when you switch back accounts your monitor is reverting to its default calibration profile, you can only revert to normal with a reboot once it messes up. In my case it’s over bright, rather than bluish.

    It is possible to fix this however, calibrating the monitor in each account should do it…have a read what I wrote in 2005 at my blog’s temporary home (redesign in process, sorry). Basically you need everyone to have permission to access a calibrated profile, you can do that by futzing with permissions or by each account having their own profile.

    These leopard issues do sound different though. Still I’d have your friend calibrate their monitor etc.

  6. The same thing happens with my iMac G5 rev. C. I thought something was wrong so I was trying to create a new display profile to fix the issue. After restarting the computer and logging in, after about 5 to 10 seconds, the tint appears. I just log into Front Row and then exit it, and the display looks perfectly normal until I restart again.

  7. It’s getting to the point where I can’t tell whether the people at TAB like macs or don’t. Green tint of death? Come on.

  8. Thanks for the suggestions – I had actually suggested that he check the color profiles next time it happened. But he’s on vacation and haven’t heard from him in a few days. Guess we’ll see.

    Rick – my friend found a couple similar instances after some googling, but he hadn’t passed the links on to me. Giving him the benefit of the doubt I made mention of the couple other findings of his. Perhaps shame on me… :)

    Anonymous – [rereading] nope, don’t see ‘green screen of death’ in there anyplace.
    Yes, I do like macs.

  9. I also have the issue that on wake-up form sleep, when the MacBook Pro just invoked the screen saver, the screen has a light bluish tint. Opening Display preferences fixes it by reloading the color calibration settings.

  10. I installed Leopard then night it came out, and have never had a green tint.

    I have a Black MacBook, so it does seem to be either a random issue, but not a common one, or a MacBook Pro issue, since G4s, and MacBooks aren’t having those issues.
