-> Mac OS has some contrast problems that make it challenging to see certain elements clearly. The Increased Contrast setting is off by default, but turning it on will improve the contrast for the operating system and in many apps. It will also turn on the "Reduce Transparency" setting. Before testing for contrast, ensure the "Increase Contrast" setting is turned on. To do this, go to System Settings > Accessibility > Display. Then, turn on the "Increase Contrast" setting.
