Build a macOS application

This page has instructions and considerations on building your Unity application for macOS.

Target architecture

Before you build an application for macOS, be aware of the chipset differences between Apple devices. Some Apple devices use Intel chipsets and others use Apple silicon. You can use Unity to create both architecture-specific builds and builds that target both Intel and Apple silicon. The available target architectures are:

Architecture 描述
Intel 64-bit Use Intel 64-bit to build for Apple devices with Intel chipsets.
Apple silicon Select Apple silicon to build for Apple devices that use the silicon architecture.
Intel 64-bit + Apple silicon Use Intel 64-bit + Apple silicon to generate a macOS build that works on both Intel chipsets and Apple silicon.

Note: This results in a build that’s larger than the individual architecture-specific builds, impacting the application size.

You can set the target architecture for your application from the macOS build settings window.

Build the application

To build your Unity application:

  1. Open the Build Settings window (menu: File > Build Settings).
  2. In the Platforms list, select PC, Mac & Linux Standalone.
  3. Set Target Platform to macOS. If macOS isn’t an option, add the Mac Build Support module to your Unity Editor install. For information on how to install modules, refer to Add modules.
  4. Set Architecture to the architecture type you want Unity to build your application for.
  5. If you want to create an Xcode project for your application, enable Create Xcode Project.
  6. Click Build.

Information property list file

macOS applications require an information property list file called Info.plist that has metadata and configuration information for the application. The file holds a list of key-value pairs.

When Unity builds your application, it creates the Info.plist file. Unity stores this file at > Contents > Info.plist. Unity displays required Info.plist configuration properties in the Player Settings window that you can set before building the application. These properties are in the Other Settings > Mac App Store Options section.

There are additional keys that you can add to your Info.plist file. To add them, build the application and use a text editor to edit the file. For information about the available keys, refer to About Info.plist Keys and Values.


macOS applications require entitlements to specify permissions and restrictions that control specific actions of your application. Your application must include entitlements that result in a Hardened Runtime. These entitlements protect your application from code injection, hijacking of dynamically linked libraries, and memory tampering.

To define entitlements, macOS applications use an XML file with the .entitlements file extension. macOS applications then use a process called code signing to bind the entitlements to an application.

If your application uses plug-ins that perform macOS platform-specific actions, you might need to add entitlements to enable those actions. For more information on what actions require entitlements, refer to Apple Developer Entitlements.

Code signing & notarization

Code signing is the process of creating a code signature for an application. This signature guarantees the integrity of applications and safeguards from any tampering. Apple devices use an application’s code signature to detect changes made after the developer created the code signature. If an application doesn’t have a code signature, the device warns the end user before they open the application. Unity automatically code signs any application it builds for macOS.

Notarization is the process Apple uses to check that Developer ID-signed applications don’t contain malicious content. Digital distribution services often require you to notarize your application before you can share it on their platform. The Mac App Store has a content validation system that’s similar to notarization, which means that applications distributed through the store don’t require prior notarization.

Refer to Code sign and notarize your macOS application for more information.
