Get a head start on your native Mac app.
Your iPad app can be made into an excellent Mac app. Now’s the perfect time to bring your app to life on Mac. The latest version of Xcode 12 is all you need. Begin by selecting the “Mac” checkbox in the project settings of your existing iPad app to create a native Mac app that you can enhance further. Your Mac and iPad apps share the same project and source code, making it easy to make changes in one place.
Optimize your interface for Mac.
Your newly created Mac app runs natively, utilizing the same frameworks, resources, and runtime environment as apps built just for Mac. Fundamental Mac desktop and windowing features are added, and touch controls are adapted to the keyboard and mouse. By default, your app will scale to match the iPad’s resolution. On macOS Big Sur, you can choose “Optimize interface for Mac” to use the Mac idiom, running your app using the native resolution on Mac. This gives you full control of every pixel on the screen and allows your app to adopt more controls specific to Mac, such as pull-down menus and checkboxes.
Even more powerful.
The new APIs and behaviors in macOS Big Sur let you create even more powerful Mac apps. Apps can now be fully controlled using just the keyboard. You can create out-of-window and detachable popovers, control window tabbing using new window APIs, and make it easier for users to select photos in your app by using the updated Photos picker. iOS Photos editing extensions can now be built to run on Mac. And your app is even easier to manage when it’s running in the background with improved app lifecycle APIs.
New and updated frameworks.
Mac Catalyst adds support for new and updated frameworks to extend what your apps can do on Mac. HomeKit support means home automation apps can run alongside the Home app on Mac. The addition of the ClassKit framework lets Mac apps track assignments and share progress with teachers and students. Plus, there are updates to many existing frameworks, including Accounts, Contacts, Core Audio, GameKit, MediaPlayer, PassKit, and StoreKit.
Tools and resources.
Download Xcode 12 and use these resources to build native Mac apps with Mac Catalyst.
Many 15-inch MacBook Pro notebooks have two graphics processors (GPU)—a discrete GPU and an integrated GPU. The discrete GPU provides substantial graphics performance but uses more energy. The integrated GPU optimizes battery life by using less energy.
Check if the discrete or integrated GPU is in use
To see which graphics cards are in use, choose Apple () menu > About this Mac. The graphics cards currently in use appear next to Graphics. Learn which integrated GPUs your Mac might have.
Check if an app is using the dedicated GPU
