What Is an M1 Mac and How Can It Run iOS Apps and Games?

An M1 Mac is a Mac built on Apple Silicon, the ARM-based chip family Apple introduced to replace Intel processors. Because the M1 shares the same underlying architecture as the chips in iPhone and iPad, it can run iOS and iPadOS apps natively rather than through emulation. Apple originally allowed this on Apple Silicon Macs, then removed the ability to install iOS apps from the Mac App Store; PlayCover is an open-source tool that restores it by sideloading decrypted IPA files and adding keyboard mapping for games.

What "Apple Silicon" and "M1" actually mean

Apple Silicon is Apple's name for its own ARM-based system-on-chip designs. The M1 was the first one shipped in Macs, followed by later variants. The key point for this topic is architectural, not marketing:

• Intel Macs used x86 processors, so iOS apps (written for ARM) could not run directly. They needed translation or a simulator.
• M1 Macs use ARM, the same instruction set family as the A-series chips in iPhones and iPads. An iOS app compiled for ARM can therefore execute on the M1 without a translation layer.

That shared architecture is the whole reason native iOS app support was possible in the first place.

Why M1 Macs could run iOS apps — and why they mostly can't now

When Apple Silicon Macs launched, Apple let developers offer their iPhone and iPad apps through the Mac App Store. If a developer didn't opt out, you could simply download and run the iOS app on your Mac.

Apple later took that feature away, and the App Store no longer surfaces those iOS apps to Mac users the way it once did. As PlayCover's own site puts it: "Apple took this feature away, so we brought it back." The hardware capability never disappeared — only the storefront path to it did.

How PlayCover brings iOS apps and games back

PlayCover is an open-source project that lets you run iOS apps and games natively on an Apple Silicon Mac, with keymapping for games. Its stated goal is to "expand Mac's App Store library" by restoring what Apple removed.

The general flow looks like this:

1. You need an Apple Silicon Mac. PlayCover targets Apple Silicon specifically — the native execution depends on that ARM architecture.
2. You supply a decrypted IPA. An IPA is the iOS app package format. "Decrypted" means the app's DRM/encryption has been removed so it can be installed outside the App Store. PlayCover does not decrypt apps for you; obtaining a decrypted IPA is on you.
3. You sideload it through PlayCover. PlayCover installs and launches the IPA as a native app on your Mac.
4. You optionally set up keymapping. For games, PlayCover lets you map touch controls to keyboard and mouse, which is the main reason people use it for titles like Genshin Impact on Mac.

Sideloading a decrypted IPA, in plain terms

"Sideloading" means installing an app without going through the official App Store. Combined with "decrypted IPA," it means: you have an app package that has had its store encryption stripped, and you install it directly. This is the mechanism PlayCover relies on. It's worth being clear that the tool handles installation and running — it does not provide the apps or remove their encryption.

Keymapping: the reason gamers care

Running an iOS game on a Mac with a mouse and keyboard is awkward if the game expects touch input. PlayCover's keymapping lets you bind on-screen touch controls to physical keys, turning a touch game into something playable with a keyboard. That's the practical difference between "it runs" and "it's usable" for many games.

What you need, and the real limitations

Before assuming this will work for a given app, keep these conditions in mind:

The honest summary: the M1's architecture makes native iOS execution possible, PlayCover restores the installation path Apple removed, and keymapping makes games playable — but you're responsible for the IPA, and compatibility varies app by app.
