The initial releases of Apple's Snow Leopard operating system, versions OSX10.6 and OSX 10.6.1, do not support ICC version 4 profiles. For this reason we are only recommending that users build version 2 profiles.

Our ColorMunki products default to version 4 profiles. To change this, click on ColorMunki Photo in your menu bar, then click on preferences. Here you can change version 4 to version 2.

Apple has recognized that they have an issue with the new version of ColorSync in 10.6.X OS. They are working on the issue and will correct it with a Software Update.
