10.4: Avoid a fast user switching color profile bug
Authored by: Skippy kangaroo on Jan 26, '07 06:46:20PM

I have also experienced this bug intermittently.

One thing I have tried that seemed to work for me as a permanent fix was to fix the permissions on the icc profiles in /Library/ColorSync/Profiles/Display.

If you look at the pre-installed one you notice that the owner is System and admin group has read/write whereas custom ones are owned by the creator and all other users have read only access. To solve the problem I selected the Displays folder and 'Got Info' - I then expanded the Ownership & Permissions section and clicked Apply to enclosed (because the Displays folder has the apparently correct permissions settings). This then gave system ownership to all the profiles there. I have yet to experience the problem again despite switching back and forth quite a bit to test it out.

Does this work for everyone? If it does it would seem to be a more permanent and more elegant fix than any of the others suggested above.

10.4: Avoid a fast user switching color profile bug

Important: For this tip to work, you must first reboot your Mac so that the missing profiles are recreated inside /Library/ColorSync/Profiles/Displays

The tip by Skippy kangaroo works great and seems to solve the issue permanently. Essentially what is needed is to change the permission on all files found inside /Library/ColorSync/Profiles/Displays to rw-rw-r-- from the default rw-r--r--

You can do that using Skippy kangaroo's technique or by opening a Terminal and typing (if you are an administrator):

sudo chmod 664 /Library/ColorSync/Profiles/Displays/*

You will be asked your password and the problem will be solved.
