iPhone and iPad apps on Apple silicon Macs

Sep 26, 2011 This is an excellent way to see what’s contained within packages, particularly the ones where the alt-click “Show Package Contents” option isn’t available, which is increasingly common starting from Mac OS X Lion and later releases of Mac OS system software, although ultimately it depends on how the package was constructed. How do you show package contents in Lion. I have a related question that is slightly more complex: I need to open / view the package contents of an installer dmg so that I can copy the necessary files to a system HD of a mac pro running Lion (10.7.5), that I have mounted on my mac mini desktop, which is running Mavericks (10.9.5). Erased the Internal SSD drive with Disk Utility and Installed Mac OS X 10.8 fresh. Booted newly installed Mac OS X 10.8 and opened App Store (App Store still works fine just a little slow rendering images). The Mac OS 10.8 App Store would ONLY download the 19MB High Sierra Installer AGAIN!!! So I proceeded with that.

The Mac App Store brings iPhone and iPad apps to Apple silicon Macs — so your apps can reach even more users worldwide. By default, your apps will be published automatically on the Mac App Store. Confirm that your apps gracefully handle cases where iPhone and iPad features are not available on Mac.

iPad apps that support modern technologies like keyboard input, multitasking, size classes, and SwiftUI will automatically inherit great macOS features like resizability and full screen mode.

Web Extensions

Safari Web Extensions can add custom functionality to Safari 14 using the same WebExtensions API used in other browsers, such as Chrome, Firefox, and Edge. And with a new conversion tool in Xcode 12, you can quickly bring your existing extensions to Safari and make them available on the Mac App Store.

Outside the Mac App Store

While the Mac App Store is the safest place for users to get software for their Mac, you may choose to distribute your Mac apps in other ways. Gatekeeper on macOS helps protect users from downloading and installing malicious software by checking for a Developer ID certificate. Make sure to test your apps with the latest version of macOS and sign your apps, plug-ins, or installer packages to let Gatekeeper know they’re safe to install.

You can also give users even more confidence in your apps by submitting them to Apple to be notarized.

The Finder is the first thing that you see when your Mac finishes starting up. It opens automatically and stays open as you use other apps. It includes the Finder menu bar at the top of the screen and the desktop below that. It uses windows and icons to show you the contents of your Mac, iCloud Drive, and other storage devices. It's called the Finder because it helps you to find and organize your files.

Change how your files are displayed

To change how files are displayed in Finder windows, use the View menu in the menu bar, or the row of buttons at the top of the Finder window. You can view files as icons , in a list , in columns , or in a gallery . And for each view, the View menu provides options to change how items are sorted and arranged, such as by kind, date, or size. Learn more about customizing views.


Gallery View, showing the sidebar on the left and the Preview pane on the right.

When you view files in a gallery, you can browse your files visually using large previews, so it's easy to identify images, videos, and all kinds of documents. Gallery View even lets you play videos and scroll through multipage documents. Earlier versions of macOS have a similar but less powerful gallery view called Cover Flow .

The sidebar in Finder windows contains shortcuts to AirDrop, commonly used folders, iCloud Drive, devices such your hard drives, and more. Like items in the Dock, items in the sidebar open with just one click.

To change the items in your sidebar, choose Finder > Preferences from the Finder menu bar, then click Sidebar at the top of the preferences window. You can also drag files into or out of the sidebar. Learn more about customizing the sidebar.

Search for files

To search with Spotlight, click the magnifying glass in the menu bar, or press Command–Space bar. Spotlight is similar to Quick Search on iPhone or iPad. Learn more about Spotlight.

To search from a Finder window, use the search field in the corner of the window:


When you select a search result, its location appears at the bottom of the window. To get to this view from Spotlight, choose “Search in Finder” or “Show all in Finder” from the bottom of the Spotlight search results.


In both Spotlight and Finder, you can use advanced searches to narrow your search results. You can also use tags to organize and find files.

Delete files

To move a file to the Trash, drag the file to the Trash in the Dock. Or select one or more files and choose File > Move To Trash (Command-Delete).

To remove a file from the Trash, click the Trash to open it, then drag the file out of the Trash. Or select the file and choose File > Put Back.

To delete the files in the Trash, choose File > Empty Trash. The storage space used by those files then becomes available for other files. In macOS Sierra, you can set up your Mac to empty the trash automatically.
