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.

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 beta and use these resources to build native Mac apps with Mac Catalyst.
During the 2000's and early '10's I worked in various IT departments. I still experience a small shiver down my spine and get a twitch in my eye when reminiscing about my days in corporate IT trying to give various network service support to my macOS clients in a Microsoft Windows-dominated world.
While most services on macOS had analogues for their Windows counterparts, printing on the big copier/printer/scanner machines proved much more tasking. Sure postscript might work depending on the copier (and that thanks was owed to CUPS from the open source world) but for our very few Mac users, printing onto machines designed to only work for Windows clients (our CFO found them to be much cheaper) was quite trying. But we managed it, and that's because regardless of what special features or doodads a printer may have, the underlying mechanism and functions are all the same. It's using this same principle that just might help you get your printer to work under macOS.
Printing from macOS
Today with AirPrint and more ubiquitous macOS support you can just about print to any printer you can buy on the market. However, there still exist some printers that support Windows only clients. I for example have an older HP 1018 printer of which there is no official macOS support. But fret not! You just might be able to find a printer driver that is 'close enough' for your printer to make it recognized on macOS. Here's how I got my HP 1018 laserjet printer to work.
Download and install the latest supported driver from HP
First, you'll need to get the latest drivers for all of the officially supported HP printers for macOS. Not from HP, but from Apple.

Luckily for us, HP tends to name it's various printers with similar feature sets with similar model numbers. So, for example, since I have an HP laserjet 1018 printer, I know that a similarly named HP laserjet like the HP laserjet 1010 or the HP laserjet 1022 may share some features with my 1018. So we try to find a best match by iteration until we get the features we absolutely want to work. Note that you may just only get printing working but extra features like duplexing or scanning might not function. But at least you can print. These instructions assume your printer is powered up and connected as expected by the manufacturer.
As with any hack, success with this 'close enough' strategy will vary by printer and by manufacturer. I also have to live with ignoring some the of the options that come with the 1022 that don't exist on my 1018 in the print dialogs when I print something. No matter. Working printer. Or, you can just buy a Mac supported printer like the HP laserjet 1022. What about you? Have a hack or tweak you want to mention? Lets know in the comments!
