***[To cut to the chase, here's the question]*** Can I-- and how do I-- convert a monitor profile created by Lacie's Blue Eye Pro software (v1.0.16) under 10.6.8 to a profile format that OS9 will recognize?

There are essentially 2 sorts of profile, V2 (version 2) and V4 (version 4). If you are creating v4 profiles with your software they are not backwardly compatible. If you create a v2 profile OS9 should see it. You may or may not be able to specify which type of profile to create in your software. I am not aware of any way to convert a v4 profile into a v2 using software. Best Matthew Ward
