Pew AAAA Mac OS

When building a .NET Core application that will run on Mac you might want to distribute it outside from Mac App Store. In this article, I will provide a step by step guide on how to package and notarize a .NET Core application to achieve distribution.

Pewanalytics is a Python package that provides text processing and statistics utilities for computational social science researchers. When you type and send certain words or phrases like Congratulations, Congrats, Happy New Year, Happy Birthday, and Pew Pew, iMessage effects are automatically attached. You and the receiver both see these effects. This works not only on the Mac but the iPhone and iPad as well.

IPv6 is an Internet Layer protocol for packet-switched internetworking and provides end-to-end datagram transmission across multiple IP networks, closely adhering to the design principles developed in the previous version of the protocol, Internet Protocol Version 4 (IPv4). Select a Mac which most closely resembles your computer. Click the heading of the type of Mac (e.g., iMac) which resembles your computer, then check the box next to the type of Mac which uses your computer's graphics card settings. MacPaw is a software development company with headquarters in Kyiv, Ukraine that produces software cleaning tools and various apps for macOS and iOS.The company was founded in 2008. MacPaw was founded in 2008 by Oleksandr Kosovan, while he was still an undergraduate student at Kyiv Polytechnic Institute.Kosovan named the company 'MacPaw' after Apple's operating systems Mac OS.

Let’s Start!

For this guide, I created a simple .NET Core Console application that outputs “Hello World”. Now let’s go step by step:

Pew AAAA Mac OS

1. Publish app as self-contained

We use the following command in Terminal to publish for macOS:

Pew aaaa mac os x

By publishing the app as self-contained it produces a macOS 64-bit executable.

If you created the application on Windows, make sure to run chmod +x AppName (Path to unix executable) from a Unix machine. Otherwise, the app will not start on macOS. To create an app bundle there are several ways to achieve this:

You can find more information about this here.

2. Create an app bundle

To create an app bundle there are several ways to achieve this you can follow this awesome guide or use a tool that generates it. For this sample, I’m using Platypus which provides a graphical user interface for creating a Mac Application bundle based on a shell script.

1) In the Platypus Script Path

Create a new script with the following:

APP_NAME is the name of your application Unix executable file

In the specific case of this sample the script content is:

2) Fill the following information:
– App Name: Name of the application
– Icon: Application icon
– Identifier: Bundle identifier of the application
– Author: Author of application
– Version: The version number of application build

3) Add all files that were generated when the app published as self-contained (including the Unix executable) to Platypus bundled files.

4) Click on Create App

Voila!

But there’s a problem if we open the generated app bundle in other Mac we will get the following result:

To avoid this we need to notarize the application that brings us to our next step.

3. Create a Developer ID Application

To be able to distribute outside of the Mac App Store we need to use a Developer ID Application certificate.

4. Use the notarization script

I created a bash script called app_notarizer.sh that allows you to do the following:

  • Create a notarization request
  • Check notarization request status
  • Staple the notarization to your app.

Script Requirements:

  • XCode
  • Apple Id Account app-specific Password (https://support.apple.com/en-us/HT204397)
  • Apple Developer ID Application Certificate created and installed in Keychain Access (https://developer.apple.com/support/developer-id/)

By using this script you can notarize the application by following these steps:

1) Create a notarization request
2) Check notarization request status
3) Once notarization status comes as successful, staple notarization

For information on the script:

Create a notarization request:

Notarization request is created by executing the following command:

For this sample, I used this App.entitlements file. you can find more information on entitlements here.

If successful we get a response similar to this one :

We will use the RequestUUID (39d40f6e-510b-497f-9edd-92ac4e128e54 ) to check the status in the next step.

Check notarization request status

We can check the notarization request status by using the following command:

It might take a few minutes to change from processing to approved or invalid. But if approved here is the response we get:

Also should receive an email:

If you get invalid as status or run into any other issue please check: https://developer.apple.com/documentation/xcode/notarizing_macos_software_before_distribution/resolving_common_notarization_issues

Staple notarization

Finally, we need to staple the notarization to the application.

We can do it with the following command:

Now we can successfully distribute our .NET Core console application!

Special thanks to Lorenzo Araujo who helped me create this amazing script.

You can find the source code and notarization script of this sample here.

Happy macOS Notarization!
