A Mac User Switching Colour Profile Bug Workaround

As with any platform, there are always the odd one or two bugs or quirks that annoy you. With the Mac, ever since we got a MacOS 10.4 machine, there is one that annoys me with the Fast-User switching. If you’ve not come across the feature, it allows the Mac to be logged on as me, and for Beth to come and check her e-mail without my having to log off – Windows XP will do something similar (although without the flashy MacOS X rotating cube effect).

However, I have a calibrated monitor profile set up on my account, that has a slightly darker, higher contrast set up to the default set up that Beth uses on her account. When the machine swaps over to her account, and then back to mine, I’m left stuck in Beth’s high contrast profile. More than that, the colour profile control panel doesn’t allow me to change back to my profile since the profile it is using is Beth’s, not mine.

However a few days ago, the MacOSXHints Weblog came up with a solution that is as simple as running the DMProxy application that is buried deep in the core graphics libraries. Beth has just checked her e-mail, the colour profile messed up, but I’ve tried it and it works. The page explains the problem (with an example screenshot of the effect) and goes through the solution, and how to set up a quick shortcut too.
