MacOS Catalina gives you privilege to Enable Auto Dark Mode on Mac, MacBook Air, and MacBook Pro.Last year macOS Mojave’s popular feature was Dark Mode and I can still see how people were excited to use Dark Mode on their Mac and MacBook’s. Sep 24, 2018 It's Apple by a nose. Windows 10 will soon have a dark mode, but Mac users can get a system-wide dark mode now with MacOS Mojave. Here's how to enable dark mode and what it. Dark Mode in macOS Mojave helps you focus on what’s important and lets everything else fade into the background. Turn it on to bring your work front and center, and see your desktop transform.
Here's how to enable it:
Those are the only steps required to enable Dark Mode. If you want to turn it off again, follow the same steps but this time choose the 'Light' option. While in Dark mode, the dock, menu bar, and all of your Apple apps, including Safari, Mail, Calendar, Notes, the Mac App Store, Messages, and more will feature darker colors and themes. Dark Mode will need to be built into third-party Mac apps that don't already offer a dark option when macOS Mojave is released. GuidesUpcomingFront Page Stories

Update colors, images, and behaviors so that your app adapts automatically when Dark Mode is active.
Overview
In macOS and iOS, users can choose to adopt a system-wide light or dark appearance. The dark appearance, known as Dark Mode, implements an interface style that many apps already adopt. Users choose the aesthetic they prefer, and can also choose to toggle their interface based on ambient lighting conditions or a specific schedule.
All apps should support both light and dark interface styles, but might perform better with a specific appearance in some places. For example, you might always adopt a light appearance for printed content.
Before you change your code, turn on Dark Mode and see how your app responds. The system does a lot of the work for you, and if your app uses standard views and controls, you might not need to make many changes. Standard views and controls automatically update their appearance to match the current interface style. If you already use color and image assets, you can add dark variants without changing your code.
Choose Adaptive Colors for Your UI
Choose colors that adapt automatically to the underlying interface style. Light and dark interfaces use very different color palettes. Colors that work well in a light appearance may be hard to see in a dark appearance, and vice versa. An adaptive color object returns different color values for different interface styles.
There are two ways to create adaptive color objects:
You configure custom color assets using Xcode’s asset editor. Groupme for mac. Add a Color Set asset to your project and configure the appearance variants you want to modify. Use the Any Appearance variant to specify the color value to use on older systems that do not support Dark Mode.
![]()
To load a color value from an asset catalog, load the color by name:
When you create a color object from a color asset, you do not have to recreate that object when the current appearance changes. Each time you set the fill or stroke color for drawing, the color object loads the color variant that matches the current environment settings. The same is true for semantic colors such as
labelColor , which adapt automatically to the current environment. By contrast, color objects you create using fixed component values do not adapt; you must create a new color object instead.
Note
For the user's content, always preserve colors that the user explicitly chooses. For example, a painting app should not try to change colors that the user applies to their canvas. Use adaptable colors primarily in the views and controls for your app’s chrome.
Create Images for All Appearances
Make sure the images in your interface look good in both light and dark appearances. Interfaces use images in many places, including in buttons, image views, and custom views and controls. If an image is difficult to see when changing appearances, provide a new image asset that looks good in the other appearance. Better yet, use a symbol image or template image, which define only the shape to render and therefore do not require separate images for light, dark, and high-contrast environments.
For information about configuring images for both light and dark interfaces, see Providing Images for Different Appearances.
Update Custom Views Using Specific Methods
When the user changes the system appearance, the system automatically asks each window and view to redraw itself. During this process, the system calls several well-known methods for both macOS and iOS, listed in the following table, to update your content. The system updates the trait environment before calling these methods, so if you make all of your appearance-sensitive changes in them, your app updates itself correctly.
If you make appearance-sensitive changes outside of these methods, your app may not draw its content correctly for the current environment. The solution is to move your code into these methods. For example, instead of setting the background color of an
NSView object's layer at creation time, move that code to your view’s updateLayer() method instead, as shown in the code example below. Setting the background color at creation time might seem appropriate, but because CGColor objects do not adapt, setting it at creation time leaves the view with a fixed background color that never changes. Moving your code to updateLayer() refreshes that background color whenever the environment changes.
Choose Visual-Effect Materials Based on the Intended Usage
Visual-effect views add transparency to your background views, which gives your UI more visual depth than if the backgrounds were opaque. To ensure that your content remains visible, visual-effect views blur the background content subtly and add vibrancy effects to adjust the colors of your foreground content automatically. The system updates these effects dynamically, ensuring that your app's content remains visible when the underlying content changes.
Use visual-effect views in your interface as container views, and add subviews to them to represent your foreground content. Configure each visual-effect view with the material or effects that are appropriate for the appearance you want:
![]()
Important
Do not use deprecated materials, such as
NSVisualEffectView.Material.light , in macOS 10.14 and later because those materials do not adapt to Dark Mode. Instead, choose newer materials that adapt correctly to the environment.
Opt Out Only as Needed
Make every effort to adopt both light and dark appearances in your apps. If supporting one appearance makes no sense for all or part of your app, you can opt out of appearance changes in the appropriate windows or views. For example, you might always use a light appearance for your app's printing views.
You can configure all or part of your interface to opt out of a specific appearance. You can also adopt a specific appearance for your entire app. For more information, see the following:
Avoid Expensive Tasks During Appearance Transitions
When the user toggles between light and dark interfaces, the system asks your app to redraw all of its content. Although the system manages the drawing process, it relies on your custom code at several points during that process. Your code must be as quick as possible and not perform tasks unrelated to the appearance change. In macOS, AppKit usually creates transition animations during appearance changes, but it aborts those animations if your app takes too long to redraw itself.
TopicsChoosing a Specific Appearance for Your macOS App
Adopt a specific appearance for your windows, views, or app when it is inappropriate to support both light and dark variants.
Choosing a Specific Interface Style for Your iOS App
Adopt a specific interface style for your views, view controllers, or app when it is inappropriate to support both light and dark variants.
