The safest place to get apps for your Mac is the App Store. Apple reviews each app in the App Store before it’s accepted and signs it to ensure that it hasn’t been tampered with or altered. If there’s ever a problem with an app, Apple can quickly remove it from the store.
Make sure your app qualifies: Review it against these App Store guidelines. Fix up anything you need to first. Fill in your app meta data: App Store Connect is a website where you can create your app listing and fill in all the important details such as title, description, keywords and more. You’ll also set your screenshots and any preview videos that you want to add. To get started, simply hit up Web2Desk’s site. If it doesn’t already have an app for a service you like, just enter the website’s address, give your app a name, pick an icon (or create your own—PNG.
If you download and install apps from the internet or directly from a developer, macOS continues to protect your Mac. When you install Mac apps, plug-ins, and installer packages from outside the App Store, macOS checks the Developer ID signature to verify that the software is from an identified developer and that it has not been altered. By default, macOS Catalina also requires software to be notarized, so you can be confident that the software you run on your Mac doesn't contain known malware. Before opening downloaded software for the first time, macOS requests your approval to make sure you aren’t misled into running software you didn’t expect.
Running software that hasn’t been signed and notarized may expose your computer and personal information to malware that can harm your Mac or compromise your privacy.
View the app security settings on your Mac
By default, the security and privacy preferences of your Mac are set to allow apps from the App Store and identified developers. For additional security, you can chose to allow only apps from the App Store.
In System Preferences, click Security & Privacy, then click General. Click the lock and enter your password to make changes. Select App Store under the header “Allow apps downloaded from.”
Open a developer-signed or notarized app
If your Mac is set to allow apps from the App Store and identified developers, the first time that you launch a new app, your Mac asks if you’re sure you want to open it.
An app that has been notarized by Apple indicates that Apple checked it for malicious software and none was detected:
Prior to macOS Catalina, opening an app that hasn't been notarized shows a yellow warning icon and asks if you're sure you want to open it:

If you see a warning message and can’t install an app
How do i delete apps from my mac desktop. If you have set your Mac to allow apps only from the App Store and you try to install an app from elsewhere, your Mac will say that the app can't be opened because it was not downloaded from the App Store.*
If your Mac is set to allow apps from the App Store and identified developers, and you try to install an app that isn’t signed by an identified developer or—in macOS Catalina—notarized by Apple, you also see a warning that the app cannot be opened.
If you see this warning, it means that the app was not notarized, and Apple could not scan the app for known malicious software.
You may want to look for an updated version of the app in the App Store or look for an alternative app.
If macOS detects a malicious app
If macOS detects that an app has malicious content, it will notify you when you try to open it and ask you to move it to the Trash.
How to open an app that hasn’t been notarized or is from an unidentified developer
Running software that hasn’t been signed and notarized may expose your computer and personal information to malware that can harm your Mac or compromise your privacy. If you’re certain that an app you want to install is from a trustworthy source and hasn’t been tampered with, you can temporarily override your Mac security settings to open it.
In macOS Catalina and macOS Mojave, when an app fails to install because it hasn’t been notarized or is from an unidentified developer, it will appear in System Preferences > Security & Privacy, under the General tab. Click Open Anyway to confirm your intent to open or install the app.

The warning prompt reappears, and you can click Open.*
The app is now saved as an exception to your security settings, and you can open it in the future by double-clicking it, just as you can any authorized app. Mac server app caching.
*If you're prompted to open Finder: control-click the app in Finder, choose Open from the menu, and then click Open in the dialog that appears. Enter your admin name and password to open the app.

-->This guide offers an introduction to creating your first Blazor web app. For more in-depth guidance, see Introduction to ASP.NET Core Blazor.
ASP.NET Core Blazor supports two different hosting options; Blazor WebAssembly (WASM) or Blazor Server. Visual Studio for Mac supports both hosting models. Visual Studio for Mac 8.4+ supports Blazor Server and Visual Studio for Mac 8.6+ supports both. For more info on Blazor hosting models see ASP.NET Core Blazor hosting models. Support for debugging Blazor WebAssembly projects in Visual Studio for Mac is available in the Preview release of v8.8 (available via the Preview update channel in the Visual Studio > Check for Updates.. menu).
What is Blazor? Blazor is a framework for building interactive client-side web UI with .NET, which offers the following advantages to web developers:
- Write code in C# instead of JavaScript.
- Leverage the existing .NET ecosystem of .NET libraries.
- Share app logic across server and client.
- Benefit from .NET’s performance, reliability, and security.
- Stay productive with Visual Studio on PC, Linux, and macOS.
- Build on a common set of languages, frameworks, and tools that are stable, feature-rich, and easy to use.
Create a new Blazor WebAssembly project
- On the Start Window, select New to create a new project:
- In the New Project dialog box, select .NET Core > App > Blazor WebAssembly App and select Next:
- Select .NET Core 3.1 as the target framework, then select Next.
- Choose a name for your project, and add Git support if desired. Select Create to create the project.Visual Studio for Mac opens your project in the Code layout window.
- Select Run > Start Without Debugging to run the app.Visual Studio starts Kestrel, opens a browser to
https://localhost:5001
, and displays your Blazor web app.
Creating a new Blazor Server project
- On the Start Window, select New to create a new project:
- In the New Project dialog box, select .NET Core > App > Blazor Server App and select Next:
- Select .NET Core 3.1 as the target framework, then select Next.
- Choose a name for your project, and add Git support if desired. Select Create to create the project.Visual Studio for Mac opens your project in the Code layout window.
- Select Run > Start Without Debugging to run the app.Visual Studio starts Kestrel, opens a browser to
https://localhost:5001
, and displays your Blazor web app.
Blazor support in Visual Studio for Mac
Visual Studio for Mac (starting with version 8.4) includes new features to help you create new Blazor server projects. As well, it provides you the standard support you would expect such as building, running and debugging Blazor projects. In Visual Studio for Mac 8.6 support for creating, building and running Blazor WebAssembly projects was added.
In the walkthrough above, we saw how the Blazor Server App project template helps you create a new Blazor Server App or Blazor WebAssembly App project. Let's take a look at some of the additional features in Visual Studio for Mac to support Blazor project development.
Editor support for .razor files
Visual Studio for Mac includes support for editing .razor files - the majority of the files that you’ll be using when creating Blazor applications. Visual Studio for Mac provides full colorization and completion support for your .razor files including completions for Razor components declared in the project.
Publishing Blazor applications to Azure App Service
You can also publish Blazor applications directly to Azure App Service. If you don’t have an Azure account to run your Blazor app on Azure, you can always sign up for a free one here that also comes with 12 months of free popular services, $200 in free Azure credits, and over 25 always free services.
Project anatomy
Blazor web apps include a few directories and files by default. As you're getting started, here are the main ones you'll need to be familiar with:
Pages folder
This folder contains a project's webpages, which use a .razor file extension.
Shared folder
This folder includes shared components, also using the .razor extension. You'll see that this includes MainLayout.razor, which is used to define common layout across the application. It also includes the shared NavMenu.razor component, which is used on all pages. If you're creating reusable components, they'll go in the Shared folder.
App settings
The appSettings.json file contains configuration data such as connection strings.
For more information about configuration, see the Configuration in ASP.NET guide.
wwwroot folder
This folder contains static files, such as HTML, JavaScript, and CSS files. For more information, see Static files in ASP.NET Core.
Program.cs
This file contains the entry point for the program. For more information, see ASP.NET Core Web Host.
Blazor Server App specific files
App settings
The appSettings.json file contains configuration data such as connection strings.
For more information about configuration, see the Configuration in ASP.NET guide.
Startup.cs
This file contains code that configures app behavior, such as whether the app requires consent for cookies. For more information, see App startup in ASP.NET Core.
Summary
In this tutorial, you saw how to create a new Blazor Server App or Blazor WebAssembly App in Visual Studio for Mac, and learned about some of the features that Visual Studio for Mac offers to help you create Blazor applications.
