Fix Blue Tint Wake from Screensaver Mac / Macbook

By | November 23, 2007

Ever wake your Mac from screensaver and find a bizarre blue tint or blueish tint to the display screen? The blue tinge can be fixed or removed by opening up Display Preferences (from System Preferences Panel, Second Row [Hardware] => Displays). Simply opening the Displays preference window reverts the color profile to the last good color profile, effectively removing the blue tinge.

UPDATE: This permanent fix does not appear to work once you’ve changed your screensaver (or perhaps at all.  The above solution still works.) A more permanent fix to the sporadic blue tint, which may or may not work for you , is to change the file permissions on the color profiles located in /Library/ColorSync/Profiles/Displays. Note that this directory is not within your home directory, but the “root” of your volume or hard disk. You won’t normally be able to get to this directory through Finder alone so it’s time to use the Terminal to fix this.

UPDATE 2: Permanent Workaround – Sleep Display.  I haven’t seen a blue tint on my Macbook Pro screen for over a year now.  Then again, I no longer use a screen saver, rather, I sleep my display after a few minutes of idle time.  This is done in System Preferences -> Energy Saver -> adjust the slider for “Put the display to sleep when the computer is inactive for: ” 10 minutes or whatever time you like.  Although I no longer have beautiful screensavers dancing across my screen, I also never have to open up Display Preferences to get rid of the annoying blue tint after waking from a screen saver.  Note: I use a “Santa Rosa” MacBook Pro which has an LED backlit screen.  This display instantly reaches full brightness whenever the screen turns on or wakes from sleep.  I could imagine this workaround being annoying for those who have flourescent tube backlit monitors/screens, which would take a minute or two to reach full brightness and operate at full colour depth.

In your Applications folder, find the Utilities folder. Apple Utilities Folder in Applications

Within Utilities is the Terminal program. Double click Terminal to launch the program.

We need to change the permissions of the /Library/ColorSync/Profiles/Displays files so lets first go to that directory by entering the following into the Terminal:

cd /Library/ColorSync/Profiles/Displays

Next, we need to enter the command to change permissions. Enter this into Terminal:

sudo chmod 664 *

Terminal will then ask you for your password. Enter your password, hit Enter and the command will be executed.

After this, try starting your screensaver manually by opening System Preferences => Desktop & Screen Saver, clicking on the Screen Saver tab near the top middle, then clicking on the Hot Corners button at the bottom left. On the bottom right corner (or another corner of your choice), choose from the list / drop down box “Display Screen Saver”.

Click Ok then try starting the Screen Saver manually by moving your mouse into the “Hot Corner” you just created. Wake out of the Screen Saver by pressing the “fn” key (lower left hand corner of the keyboard) if you’re on a laptop or Shift if you’re on a desktop Apple. Repeat this multiple times, waiting varying lengths of time before waking out of the screensaver. Hopefully the blue tint should no longer occur after waking from the screen saver.

    Thanks, it was driving me a little crazy. The permission thing seemed to solve it for me. I also, while I was in the preference area, calibrated the LCD. I always thought the screen had this yellowish tint to it all.

    Trippy. This happened to me while I was using VMware Fusion, and an iCal Event Reminder window popped up. Fortunately, opening the Displays preferences pane returned everything back to normal.

    This is the only post that I found on the net that was helpful with this topic, thanks for putting it up. I tried changing the permissions, but it didn’t keep it away completely. If I test the screen saver and get out of it repeatedly this still shows up. Any more ideas? If not, thanks anyway.

    Hi Ellis,

    I updated this post with a workaround: using Energy Saver – Sleep Display, rather than a screen saver. This method of “screen saving” doesn’t using moving images, rather a lack of any image. More boring, but then again it’s more environmentally friendly and doesn’t “stress” your liquid crystals (yeah, I know I’m reaching with that one).

    Best regards,

    Ben

    I used a simple shortcut to fix:
    Ctrl + Shift + Eject

    The screen will sleep, then move the mouse or press any key to wake again. The color becomes normal again.

    doing the whole terminal thing did not work and it said i was “not in the sudoers file. this incident will be reported.” .. so whats gonna happen now?
    then i tried the ctrl+shift+eject trick, which also did not work. oh and going to the displays preference pane didnt fix the blue screen either.

    any more ideas? thanks.

    This is great, thanks. I thought my eyes were going bad because I usually notice it when coming back from lunch after having been out in the sunshine for a while!

    Thanks :). The blue was driving me crazy – I thought it was my vision. My MacBook (2008) wouldn’t wake up from sleep mode in the middle of my exam – freaked cuz I thought I lost all my stuff. Turns out I didn’t, but I got the blue tint glitch.

    Thanks! The very first quick fix worked. I thought my eyes were playing tricks on me. Blue color showed up right when I turned the computer on. This is the first time it’s ever happened on my MacBook (2008).

    These solutions all seem very technical and overly complicated compared to what i did… system preferences, display, colour, then choose color LCD. The blue tint on my screen was apparently due to it being set to Adobe RGB (1998)

    Opened System Preferences, Hardware, Displays…. hey presto! Thank you so much.

    I followed the directions and it changed my permissions to my folders. So, when I rebooted my desktop went to the default and my files said they couldn’t be found. I went to the disk utility first and repaired the permissions. Then to the hard disk>User and highlighted each folder>went to file>get info> and changed the permissions back from custom to RW ect.

    What a pain this has been, it’s still blue.

    I found another article that says we’re just SOL, because apple has no intension to fix.
