Apple controls the way you use the software you download from its App Store quite tightly, and it's very difficult to run your iPad and iPhone apps on another platform, such as your desktop Mac. You can’t natively run iPad apps on a Mac computer without using an emulator, though that will change with a new generation of Macs, set to come out by the end of 2020. The new Macs will run on new Apple-designed chips that are similar to the ARM chips in iPadOS devices, making them compatible.
MacOS Catalina's iPad apps for the Mac are here, but the story is just getting started. Catalyst has been slow to take off on MacOS 10.15, but here's a look at the state of tablet apps migrating.

If you want to run apps from your iPad on a Mac, the traditional answer is that you can’t – at least not ordinarily. There is an exception — you can use an iPadOS emulator on your Mac. Read more about that below. But at this time, iPad apps are fundamentally incompatible with the architecture and operating system on a Mac computer. That is changing, though.
You’ll be able to run iPad apps on some Macs soon
At the beginning of 2020, Apple announced that it would soon start to produce Mac computers with its own Apple-designed chipsets, abandoning the Intel chips it has used for many years. When it does this, the new Macs — which will share a similar architecture to iPadOS devices — will be able to run iPad apps.
Apple has made its own ARM-based chips for iOS and iPadOS devices for years. ARM chipsets are characterized as low-power processors commonly found in mobile devices like phones, tablets, and some laptops, optimized to deliver the best battery life. Starting late in 2020, Apple is expecting to release MacBooks and other Mac computers with similar high-performance ARM chips.
Because of the similar architecture, Apple has already announced that this will allow Apple computers to natively run iPad apps with no further changes or modifications. You’ll be able to install iPad apps directly from the Mac’s app store.
The exact timing is uncertain, but the first of these new Macs are expected before the end of 2020. Keep in mind that for quite some time to come, there will be both Intel chipset and Apple chipset Macs around, and only the ones with Apple chipsets will be able to run iPad apps. This might be a little confusing until most Intel-based Macs have been retired.
Running iPad apps with an emulator
The new Macs may be coming soon, but that’s not the entire story. Because software developers need to be able to test iPadOS apps quickly and easily, they sometimes use emulator software to run iPad apps on their Macs.
There are a handful of emulators available for the Mac that can run iPad apps, but these programs are not easy to install or manage, and it’s generally not possible to install apps from the Apple App Store – you’re limited to just apps you developed yourself and have stored locally. One of the most common emulators to use is Xcode, which is a simulator offered by Apple.

Emulators
Both Macintosh emulators available on iOS we’re ported by @maczydeco who has done an amazing job making them feel truly at home on iOS. Many thanks! They need to be built from source using Xcode but it’s a pretty straight forward process.
Mini vMac
- Supports System 1.1 to 7.5.5
- Limited RAM and CPU emulation
- File Sharing via bespoke method
- No dynamic screen resolution changing
- Odd interface using Control key shortcuts
BasiliskII
- Supports System 7.0 to 8.1
- Advanced RAM and CPU emulation
- File Sharing via mapped folder
- Dynamic screen resolutions through Monitors control panel, or automation
- Native iOS interface for settings panel, negating all the issues with the desktop GUI
- We have a winner!
- Source code (use the
iosbranch)
File Sharing
This works a treat in both emulators, but the experience is better in BasiliskII.
Emulate Ipad On Mac
With Mini vMac you need to run a special file import app, and then whilst it’s open use iOS Share Sheet to send a file to Mini vMac. These extra steps are just enough friction to make the emulator annoying to use.
With BasiliskII things are easier as it has a drive mapped to the app’s file sharing folder. You can use the Share Sheet in the same way as Mini vMac, but you can also simply copy/move a file to the BasiliskII folder and it will be accessible inside the emulator. The only gotcha with this approach is that you’re best moving the file to the emulated system’s main disk drive otherwise you’ll encounter various oddities with certain apps that don’t know how to cope with files located on this type of drive.
Screen Resolutions
The original Macintosh had a native screen resolution of 512×342.
Conceptually, the iPad has a logical screen resolution of 1024×768, which when running in pixel doubled mode equates to 512×384. A pretty good match. Specifically, the native resolution varies according to the model of iPad or iPhone you are using.
I use an iPad Pro 12.9” which has a native resolution of 2732×2048, pixel doubled that means 1366×1024, and pixel quadrupled 683×512. Targeting this ballpark of resolution means user interface elements will be around the magic 44pt tappable area, so that fingertip interactions are accurate, predictable and enjoyable.
Of course the iPad can flip between landscape and portrait orientations on demand, which means BasiliskII supporting the Monitors control panel is a big win.
So I added a bunch of custom resolutions to the BasiliskII soure code to add support for both pixel-doubled and pixel-quadrupled resolutions, in both portrait and landscape, with and without room for the software keyboard. I can switch between these resolutions with keyboard shortcuts. Which leads nicely on to…
Custom Keyboards
Both emulators share the same software keyboard mechanism. The keyboard layouts are user-editable as JSON and compiled into a custom format.
So I put together a custom keyboard layout that can be used in either emulator that gives me quick thumb access to tools and shortcuts in my most used apps: artWORKS and UltraPaint. It works for both apps as they are closely related, sharing a lot of code and resources.
With this keyboard layout I’m not only relabelling the function keys, but also replacing some key codes to reposition keys for my own purposes. The apps don’t respond to function keys so I use macros and Apple Events to get things to work as detailed in another post.
How does the experience compare to a real Macintosh?
The most important aspect of this setup is that it runs System 7 and the various apps I use. That is the core of my classic Macintosh experience and the goal I had in mind. The hardware running System 7 is merely a conduit.
That said, the iPad Pro is more portable, reliable and capable than my real Macintosh. That’s 30 years of hardware progress for you.
The iPad’s display in particular is a huge differentiator—it can assume so many different resolutions it should be thought of as a collection of displays rather than just a single one.
Apple Pencil is very similar in feel to my Wacom ArtPad II, but with the single huge improvement that you’re drawing directly on the screen. Drawing with an Apple Pencil on System 7 is every bit as good as drawing in a native iPad app.
iOS is only a swipe away: download classic software using a modern web browser like Safari, expand archives more quickly with Files or Documents, watch videos picture-in-picture, search your Inside Macintosh PDFs in Books, listen to streaming music, and so many other things that aren’t doable (or at least are extremely difficult to do) on a real classic Macintosh.
Emulate Ipad On Mac Keyboard
Bluetooth keyboards just work. The new/recent mouse pointer support in iOS also works. You could even plug the iPad into an external display to go full circle back to a desktop computer.
This setup gives me the best of both old and new worlds, and that’s why I refer to it as the Ultimate Classic Macintosh.
