I know that there are a lot of Mac users in this forum, and I have not seen this posted previously, so I thought that I would post:

 

Mac OS X v10.6.3: Display profile reverts from custom to default after updating to Mac OS X v10.6.3

 

Basically, the recent 10.6.3 update will switch to your default display profile. So, if like me, you color calibrate your monitor the Apple update will default to a potentially uncalibrated previous profile. In my case the update also caused profile error messages in Capture One. Switching back to my calibrated profile not only corrected my monitor colors but also corrected the error message problem in C1.

Thanks, explains why my monitor was acting like a searchlight the past few days.

Thanks, I noticed the problem yesterday - my main iMac screen still looked reasonable, but the 19" screen that I used as a second monitor looked dreadful.

 

The odd thing is that the profiles don't show up if you select the option to only show profiles associated with the monitor - which I guess is symptomatic of the underlying problem the update caused.

Thanks. That explains why my Colour Navigator agent for my Eizo Coloredge screen suddenly came up as telling me I was overdue to re-profile even though I had only done so several days ago.

Great spot Chuck. Mine was subtly out having reverted back to 'default'. All sorted now.

I haven't even seen the 10.6.3 update yet - but forewarned is forearmed - Thanks!

 

BTW, my experience is that profiles created by third party hardware (e.g. my Optix Pro) have NEVER (in 5 years) shown up in the short list of "Show only profiles for this monitor". Only the ones created with Apple's own calibrating utility get that privilege.

Thanks a million for the post Chuck. Explains the problems I've been having since I updated.

Thank you for the post. I am about to upgrade to SL, and you have saved me trouble and head scratching.

 

A great use of the forum.

Surely you would re-profile your monitor after installing 10.6.3? It's a major update, so not re-profiling would be madness. Monitors should be profiled regularly (at least monthly), and after any update which affects the video / display system.

 

If you are working for print principally then the settings should be:

 

Temp 5500k

Gamma 2.2

Lum 120 (100 for a darker room, 140 for a very bright room)

 

For images which will principally be viewed onscreen the settings shoudl be:

 

Temp 6500k

Gamma 2.2

Lum 120 (100 for a darker room, 140 for a very bright room)

Much appreciated- been looking at this for a week wondering why things were off. Allergies have really screwed with my eyes, so I thought it was me, although I was about ready to do a calibration to make sure.
