Wow great to see that my original solution is still helping out over a year later

Ok, so my last post is out of sync as i was replying on the move.

as an explanation as to what i think is happening regarding this issue here is what i have found..

At the college here, we run our iMac’s, Mac Books, Mac Minis and Mac Pros on an Active Directory network (not my choice i must add!). Each user has an individual user account that roams with them allowing files and settings to travel too.

The color settings are an individual preference allowing customized desktops..Great, however at each login the mac starts up and just reads the color profile that has been saved in the users preferences.

As all Macs pretty much all the color profiles built in it will use the defined one even if is the wrong monitor/display panel and not automatically re-calibrate which is where going to the color tab of the display preferences sits.

The OS itself will just muddle through along with most programs, the FC suite of programs is, so far, the only program i have found with a specific requirement for the correct profile (i guess it knows the display type and requires the correct profile selected) or in the case of the missing profiles folder, it will fall back to an os default, like the old 640×480 display of windows if something went wrong.

Long winded i know, but just wanted to explain what imho is happening, there may be a solution to this and that is to remove the profile preference at each logoff, forcing a recreation at the next login, something i will be looking into over the next month or too. i will post my findings if anyone is interested.

It may be a silly comment but…… Is the iMac setting selected(highlighted) ? many of my users see it at the top of the list and assume it is the active profile.

Seems to be fixed

After an upgrade all my students had the white screen of death on a single screen iMac running 10.5

After reading this, i did the following

1. leaving FCP running – Launched Sys Prefs
2. Opened display options
3. selected the Colour tab
– This caused a recalibration
4. Back to FCP – Played a video

All ok!

This is my working solution & I hope this helps someone
