Native Mac apps built with Mac Catalyst can share code with your iPad apps, and you can add more features just for Mac. In macOS Big Sur, you can create even more powerful versions of your apps and take advantage of every pixel on the screen by running them at native Mac resolution. Apps built with Mac Catalyst can now be fully controlled using just the keyboard, access more iOS frameworks, and take advantage of the all-new look of macOS Big Sur. There’s never been a better time to turn your iPad app into a powerful Mac app.

Designed for macOS Big Sur.
When an app built with Mac Catalyst runs on macOS Big Sur, it automatically adopts the new design. The new Maps and Messages apps were built with the latest version of Mac Catalyst.

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.
Note: this is a continuation of How to embed HTML5 into a native Mac OSX app. This tutorial uses Xcode Version 4.0.1.
So having gone through the first tutorial, you should now have a bare-bones native OSX application running your HTML5 program. Let's open that same project in Xcode (example on GitHub) and finish it up! I'll use WebViewExample as the name of this tutorial project, but just like last time, yours can be whatever you like. Sandbox for mac.
Adding an icon to your app
To set the icon that appears in the dock, Finder and other views, follow these steps: Best apps to free up ram memory mac.
- First you need an Apple Icon Image file. To make one yourself, open up the Icon Composer application (mine is located in
/Developer/Applications/Utilities/Icon Composer.app
). For the sake of speed you can use OnslaughtArena.icns. - In Xcode's left sidebar, drill down into
WebViewExample / Resources
. - Drag your
.icns
file into the Resources folder. - Still in the Resources folder, open the
WebViewExample-Info.plist
file. - In the 'Key' column, find the row with the value 'Icon file'.
- Set the value of this row to the name of your
.icns
file (eg,OnslaughtArena.icns
).
Closing the window should close the application
For those unfamiliar with OSX, I'll quickly describe what this means. In OSX, you can have an application open without any windows. This is very different from Microsoft's Windows operating system where if all the windows are closed, the application is no longer running. This can create an awkward user experience, so there must be a way to bring windows back. This flow doesn't really make much sense for games, so a good workaround is to close the application when all windows are closed.
Be sure to do this; we got rejected the first time we submitted because we did not enable this feature! Here's the reason from Apple:
We have found that if the user closes the app window, there is no way for the user to reopen the app without having to quit and relaunch the app.
Fortunately the fix is easy.
- In Xcode's left sidebar, drill down into
WebViewExample / Classes / WebViewExampleAppDelegate.m
. - In the
awakeFromNib
method, add this line just above the closing bracket:[window setDelegate:self];
. - Add this method after the
awakeFromNib
method:
That's it! Now when you close your application's main window, the application should quit. Note: this works great but it generates the warnings 'notice: Semantic Issue: Passing argument to parameter 'anObject' here' as well as 'Class 'WebViewExampleAppDelegate' does not implement the 'NSWindowDelegate' protocol'. Chrome make web app.
Logging errors
Xcode can be a bit daunting to newcomers, but fortunately it's very easy to send messages to the log. It can be done with code like this:
(These messages should appear in the main Xcode window, in the very bottom.)
Enabling localStorage
It seems that, by default,
localStorage
will not persist data in an embedded WebView as expected. Here's how to enable it:Mac Os Html5 App Tutorial
- In Xcode's left sidebar, drill down into
WebViewExample / Classes / WebViewExampleAppDelegate.m
. - Add this code to the top of the awakeFromNib method:
WebPreferences *prefs = [webView preferences];
. - Then add this line just below that:
[prefs _setLocalStorageDatabasePath:@'~/Library/YourProjectName/LocalStorage'];
. (Be sure to use the name of your project intead of 'YourProjectName'.)
It's important to name the folder that
localStorage
saves to with the same name as your application (eg, Onslaught! Arena saves to '~/Library/OnslaughtArena/LocalStorage'
)! Apple will reject your app if it puts data somewhere unexpected. Can not open apps or documents mac.Mac Os Html5 App Download
Note: this may generate the warning 'WebPreferences' may not respond to '-_setLocalStorageDatabasePath:'.
Summary
Your application should now meet the bare essentials for submission to the Mac App Store, and you could be reaching a wider audience with your HTML5 app in no time (pending Apple's approval …). Did I miss anything you were hoping to know about? Any steps not work for you? Please let me know.
Bonus: if you want to see what kind of quality you can get out of a native OSX HTML5 app, we just dropped the price of Onslaught! Arena in the Mac App Store to $1.99! See HTML5 in action for yourself.
