As Big Sur came onto our Macs I noticed that destructive button's text in NSAlert controller are colored in red as shown in picture.

I wasn't able to find a way to bring this feature in my app.

Using the standard addButton(withTitle:) method we haven't any way to set its intent (such as default, cancel or destructive).

Can you give me any hint?

Thanks

Set the property hasDestructiveAction of the button to true . This property is new in Big Sur.
