After upgrading to macOS Sonoma, I can't see the yellow insertion point against the white background in Pages.
Is there a way to adjust or override the accent color of individual apps?
Yes. The accent color and, by extension, the color of the insertion point can be adjusted on a per-app basis by assigning a value to the
AppleAccentColor preferences key within the application's preferences domain.
The available accent colors are identified by an integer value as follows:
For Pages, the domain would be
com.apple.iWork.Pages, so setting the accent color to the standard system blue would be done by using the
defaults Terminal command below:
defaults write com.apple.iWork.Pages AppleAccentColor -integer 4
To revert the change use the
defaults delete com.apple.iWork.Pages AppleAccentColor
