I think this is a duplicate of an old question without a good answer: Display appears different on two accounts using same color profile
My child was doing schoolwork on her school-issued Macbook Air. Suddenly lighter greys are totally white. This generally gives the images on the screen a vague feeling of being "off", and pixellates all curved edges. The biggest problem is that text on some of her sites is unreadable.
I've checked the following:
- Color profiles - it looked like it was using the default, but a cycled through a few built-ins. I could see noticeable changes to color balance, but the light greys remained the same as white. Also deleted contents of
- Accessibility - my child has accidentally inverted colors before, this isn't that. No other accessibility settings seemed related to color.
- Display settings - Modifying brightness was also fruitless. The screen overall got brighter or darker, but still couldn't distinguish between light grey and white
- Rebooting - colors look fine until shortly after logging in - seems connected to user profile somehow.
Any solution would be appreciated, but if there is a keyboard shortcut that can cause this, it would be the most likely explanation (8 year old says they "might have rested their arms on the keyboard" during a class meeting)
