If you have a Mac supported by Apple Silicon, you no longer need to remove your iPhone or iPad to run some of your favorite mobile apps. If you are using macOS 11Big Sur or later, you can download and install the iPhone and iPad applications on your Mac.

Before you can run an iPhone or iPad app on a Mac or MacBook, you must first download it from the Apple App Store.
Get started by clicking on the Launchpad icon on the bottom of your computer.

Then click the "App Store" button. If you can't find it, use the search bar to find the app.

Alternatively, you can use the built-in search Apple Spotlight to open the application. The easiest way to do this is by pressing Cmd + Space Bar on your keyboard. The dialog box search will appear in centre of screen your. Enter "App Store" and select the first entry.

You can now enter the name of the iPhone or iPad app in the search bar in the upper left corner of the window.

You will not see her right away application you are looking for - this is because the App Store is the default to display only Mac applications Click on the "iPhone & iPad Apps" list to switch between views.

If the iPhone or iPad app developer chooses to make the Mac app available, you will now see it on the results.
Click the "Get" or Download button to begin the download process.

Once the iPhone or iPad app is installed on your Mac, select the "Open" button. The application will open on its own window and will be executed like any another application developed for your Mac.

Later, after closing the App Store, you can open and run the iPhone or iPad app on your Mac by locating it in the Launchpad or using the Spotlight search, as we did above.
Unfortunately, there are no Macs with touch screens so you need to interact with the trackpad, the mouse or your keyboard, in all the applications or games you have downloaded.
