How to increase the contrast on the Mac screen

Over the past few years, Apple has modernized the macOS interface by increasing transparency, flattening elements and adding whitespace. If you find the new interface difficult to use, try increasing the contrast.

'Increase Contrast' is one of the many useful features in macOS. It makes it easier for users with low vision to read computer screens, but anyone can use this feature to make the interface easier to read.

Once enabled, every UI element (whether it's just a text box or button) has a distinctly black border around it. This makes it easier to locate a node and know where one part of the application ends, as well as where another begins.

You can enable this feature from the macOS System Preferences . Click the Apple button from the menu bar and then select System Preferences.

Next, click on the 'Accessibility' button .

From the left sidebar, select the 'Display' option.

Here, click the checkmark next to 'Increase Contrast'.

Now you will see that the whole UI has borders around every element and, as an added benefit, the transparency effect is gone. When you enable the 'Increase Contrast' feature, macOS also automatically activates the 'Reduce Transparency' option.

When you want to turn this feature off, go back to Display in Accessibility and click the checkmark next to the 'Increase Contrast' option.

Hope you are succesful.
