December 12, 2006: A fix for wonky color profiles in Mac OS X
For when your Mac's screen's colors go weird after fast user switching.

A while back I was in a meeting at work and had my iBook with me. I thought the screen colors looked very blue, and went to the Color tab of the Displays pane in System Preferences, where I noticed that it was set to use the Generic RGB Profile. Now, I’m pretty sure that I calibrated it at some point, but checking the “Show profiles for this display only” showed only the profile “Color LCD”. And if I tried selecting any profile at all, I only got the error sound.
But some googling provided the solution, and results in a tiny Applescript application residing in my dock:
'tell application "Terminal"
open file "/System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/CoreGraphics.framework/Versions/A/Resources/DMProxy"
quit
end tell
(That’s one long file path!)
It seems like there’s a bug with fast user switching and color profiles in Mac OS X, and running the DMProxy application fixes it—not that I know exactly how, but it works—at least for a while. Which is why you need to be able to run it every now and then.
And there’s another tip here: If you have a problem that you can’t find a solution for through a regular web search, try Google groups. Because if other people can’t find a solution, chances are they’ve asked in a newsgroup!
