OS X loses monitor profile

Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.

Isolating an issue by using another user account

If the problem is still there, try booting into the Safe Mode. Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application unistaller. For each disable/delete, you will need to restart if you don't do them all at once.

Troubleshooting Permission Issues

Step by Step to Fix Your Mac

Problems such as yours are sometimes caused by files that should belong to you but are locked or have wrong permissions. This procedure will check for such files. It makes no changes and therefore will not, in itself, solve your problem.

First, empty the Trash.

Triple-click the line below to select it, then copy the selected text to the Clipboard (command-C):

find ~ $TMPDIR.. \( -flags +sappnd,schg,uappnd,uchg -o ! -user $UID -o ! -perm -600 -o -acl \) 2> /dev/null | wc -l

Launch the Terminal application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.

Paste into the Terminal window (command-V). The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.

The output of this command, on a line directly below what you entered, will be a number such as "41." Please post it in a reply.

I've been using Snow Leopard for 2 years (Mac Mini) and had two different monitors in that time. I just got an Asus VE228 monitor and it was really bright and washed out. So I made a setting that looks good but it won't stay selected after a reboot.

Same thing happened. When opening the System Preferences and going to the Display section, it switches to the right profile the moment I click on the Color tab.

Repairing permissions did not fix it. I tried making a new user and it does the same thing with that user. I tried a system reinstall and it didn't help.

I tried that terminal thing above but I don't get a new line ending with $. I just get a new line with a 0.

Can anybody help me get my monitor setting to stick?

Thanks,

Scott

You might want to consider starting a new discussion. Since this one is marked solved, less people are likely to look at it.

oops, I didn't notice that. Thanks!

Hi Scott,

did you found an answer to your problem? I'm stuck with the same problem and cannot seems to find a solution.

I did find a way to fix it, but I just can't remember how. I forgot I had posted here, otherwise I would have come back and put it in here. I think it involved editing some plist files. Sorry I can't be more help. Scott

Hi Scott,

thank you for your answer. I finally solved my permissions problems with "Cocktail". I fanilly could save my Calibration through ColorSync Utility as well as Spyder4Elite. I recommend it.

Best
