What’s Happening with ColorSync in Sequoia 15.5?

Welcome to the world of MacOS! It’s great to hear that you love your Mac Mini M4, but I understand how frustrating it can be to deal with monitor profile issues. The problem you’re experiencing, where your custom monitor profile reverts to the default sRGB upon waking from sleep or exiting the screen saver, can certainly disrupt your workflow, especially for tasks like photo editing that require precision.

First, ensure that your custom display profile is set as the default profile in the Display Preferences. Go to System Preferences, then Displays, and select the Color tab. From there, choose your calibrated profile and make sure it’s specified as the default.

This may help prevent the reversion to sRGB. If the problem persists, consider resetting the NVRAM (non-volatile random-access memory) on your Mac. This can sometimes resolve issues related to display settings.

To do this, restart your Mac and immediately hold down the Option, Command, P, and R keys for about 20 seconds. This may clear any odd configurations causing your custom profile to be lost when the system sleeps. Another potential fix is to check for software updates.

Ensure that your Mac is running the latest version of MacOS, as updates often include fixes for various bugs and issues. Lastly, if these options don’t work, you might want to explore third-party calibration software that allows for better management of display profiles. Some programs offer advanced settings and can help retain your custom profiles even after sleep mode or screen saver activation.

I hope these suggestions help you maintain optimal calibration for your monitor and streamline your photo editing process. Good luck!
