macOS Big Sur takes the most advanced operating system in the world to a whole new level of power and beauty, making your apps look better than ever on an all-new interface. New widget features and the new widget gallery help you deliver more value to your users. Adding intelligence to your apps with machine learning is even simpler and more extensive with new tools, models, training capabilities, and APIs. You can create more powerful Mac versions of your iPad apps with Mac Catalyst. And you can now easily bring your extensions to Safari — and to the App Store.
To run the game on your Mac, you’ll require a system running OS X 10.12, powered by an Intel Core i5-750M or better coupled with an Intel HD 530 or better, and at least 4GB of RAM. Since the game is so massive, you’ll also need at least 70GB of free space on your system. But you don't have to wait for the iPhone 12 models to join the list of best iPhones. Plenty of apps already take advantage of AR, and if you've got an iPhone of fairly recent vintage — the. Best Mac remote access apps. But the core functionality works effectively, providing remote screen and file access, and several security options. Affordable app with core remote-access options. Among the Macs on sale currently you will generally find dual-core, quad-core, 6-core, and 8-core options. If you need more cores, the Mac Pro offers a Xeon processor with 8, 12, 16, 24, or 28-cores.
macOS Big Sur brings a new design that’s been finely tuned for the powerful features that make a Mac a Mac. Core features, such as the menu bar and Dock, take advantage of the large Mac display, with translucent backings and spacious pull-down menus. The new Control Center, designed just for Mac, provides quick access to controls while keeping the menu bar clutter-free. Notification Center puts recent notifications and powerful new widgets together in a single view for at-a-glance information as you work. And a streamlined new design for apps features full-height sidebars and integrated toolbar buttons.
Easily build widgets using the WidgetKit framework and the new widget API for SwiftUI. Widgets now come in multiple sizes, and users can visit the new widget gallery to search, preview sizes, and add them to Notification Center to access important details at a glance.
With support for the popular WebExtension API, it’s even easier to bring powerful extensions to Safari. Xcode 12 even includes a porting tool to streamline the process.
The new Extensions category on the Mac App Store showcases Safari extensions, with editorial spotlights and top charts to help users discover and download great extensions from the developer community.
With macOS Big Sur, creating apps that leverage the power of machine learning is even easier and more extensive with additional tools in Core ML for model deployment, new models and training capabilities in Create ML, more APIs for vision and natural language, and improved resources for training on Mac and converting models to Core ML format.
Create even more powerful Mac versions of your iPad apps. Apps built with Mac Catalyst now take on the new look of macOS Big Sur and help you better define the look and behavior of your apps. You can choose to turn off automatic scaling of iPad controls and layout, allowing you to precisely place every pixel on the screen. Provide full control of your app using just the keyboard, take advantage of the updated Photos picker, access more iOS frameworks, and more.
Later this year, the Mac App Store will help users understand apps’ privacy practices. You’ll need to enter your privacy practice details into App Store Connect for display on your product page.
Use Xcode 12 and these resources to build apps for macOS Big Sur.-->
In this article, you'll learn how to install .NET on macOS. .NET is made up of the runtime and the SDK. The runtime is used to run a .NET app and may or may not be included with the app. The SDK is used to create .NET apps and libraries. The .NET runtime is always installed with the SDK.
The latest version of .NET is 5.0.
The following table is a list of currently supported .NET releases and the versions of macOS they're supported on. These versions remain supported either the version of .NET reaches end-of-support.
|Operating System||.NET Core 2.1||.NET Core 3.1||.NET 5.0|
|macOS 10.15 'Catalina'||✔️ 2.1 (Release notes)||✔️ 3.1 (Release notes)||✔️ 5.0 (Release notes)|
|macOS 10.14 'Mojave'||✔️ 2.1 (Release notes)||✔️ 3.1 (Release notes)||✔️ 5.0 (Release notes)|
|macOS 10.13 'High Sierra'||✔️ 2.1 (Release notes)||✔️ 3.1 (Release notes)||✔️ 5.0 (Release notes)|
|macOS 10.12 'Sierra'||✔️ 2.1 (Release notes)||❌ 3.1 (Release notes)||❌ 5.0 (Release notes)|
The following versions of .NET are ❌ no longer supported. The downloads for these still remain published:
The runtime is used to run apps created with .NET. When an app author publishes an app, they can include the runtime with their app. If they don't include the runtime, it's up to the user to install the runtime.
There are three different runtimes you can install on macOS:
ASP.NET Core runtime
Runs ASP.NET Core apps. Includes the .NET runtime.
This runtime is the simplest runtime and doesn't include any other runtime. It's highly recommended that you install ASP.NET Core runtime for the best compatibility with .NET apps.
The SDK is used to build and publish .NET apps and libraries. Installing the SDK includes both runtimes: ASP.NET Core and .NET.
.NET is supported on the following macOS releases:
|.NET Core Version||macOS||Architectures||More information|
|5.0||High Sierra (10.13+)||x64||More information|
|3.1||High Sierra (10.13+)||x64||More information|
|3.0||High Sierra (10.13+)||x64||More information|
|2.2||Sierra (10.12+)||x64||More information|
|2.1||Sierra (10.12+)||x64||More information|
Beginning with macOS Catalina (version 10.15), all software built after June 1, 2019 that is distributed with Developer ID, must be notarized. This requirement applies to the .NET runtime, .NET SDK, and software created with .NET.
The runtime and SDK installers for .NET 5.0 and .NET Core 3.1, 3.0, and 2.1, have been notarized since February 18, 2020. Prior released versions aren't notarized. If you run a non-notarized app, you'll see an error similar to the following image:
For more information about how enforced-notarization affects .NET (and your .NET apps), see Working with macOS Catalina Notarization.
.NET applications that use the System.Drawing.Common assembly require libgdiplus to be installed.
An easy way to obtain libgdiplus is by using the Homebrew ('brew') package manager for macOS. After installing brew, install libgdiplus by executing the following commands at a Terminal (command) prompt:
macOS has standalone installers that can be used to install the .NET 5.0 SDK:
As an alternative to the macOS installers for .NET, you can download and manually install the SDK and runtime. Manual install is usually performed as part of continuous integration testing. For a developer or user, it's generally better to use an installer.
If you install .NET SDK, you don't need to install the corresponding runtime. First, download a binary release for either the SDK or the runtime from one of the following sites:
Next, extract the downloaded file and use the
export command to set variables used by .NET and then ensure .NET is in PATH.
To extract the runtime and make the .NET CLI commands available at the terminal, first download a .NET binary release. Then, open a terminal and run the following commands from the directory where the file was saved. The archive file name may be different depending on what you downloaded.
Use the following command to extract the runtime:
Use the following command to extract the SDK:
export commands only make the .NET CLI commands available for the terminal session in which it was run.
You can edit your shell profile to permanently add the commands. There are a number of different shells available for Linux and each has a different profile. For example:
Edit the appropriate source file for your shell and add
:$HOME/dotnet to the end of the existing
PATH statement. If no
PATH statement is included, add a new line with
export DOTNET_ROOT=$HOME/dotnet to the end of the file.
This approach lets you install different versions into separate locations and choose explicitly which one to use by which application.
Visual Studio for Mac installs the .NET SDK when the .NET workload is selected. To get started with .NET development on macOS, see Install Visual Studio 2019 for Mac.
|.NET SDK version||Visual Studio version|
|5.0||Visual Studio 2019 for Mac version 8.8 or higher.|
|3.1||Visual Studio 2019 for Mac version 8.4 or higher.|
|2.1||Visual Studio 2019 for Mac version 8.0 or higher.|
Visual Studio Code is a powerful and lightweight source code editor that runs on your desktop. Visual Studio Code is available for Windows, macOS, and Linux.
While Visual Studio Code doesn't come with an automated .NET installer like Visual Studio does, adding .NET support is simple.
The dotnet-install scripts are used for automation and non-admin installs of the runtime. You can download the script from the dotnet-install script reference page.
The script defaults to installing the latest long term support (LTS) version, which is .NET 3.1. You can choose a specific release by specifying the
current switch. Include the
runtime switch to install a runtime. Otherwise, the script installs the SDK.
The previous command installs the ASP.NET Core runtime for maximum compatability. The ASP.NET Core runtime also includes the standard .NET runtime.
Containers provide a lightweight way to isolate your application from the rest of the host system. Containers on the same machine share just the kernel and use resources given to your application.
.NET can run in a Docker container. Official .NET Docker images are published to the Microsoft Container Registry (MCR) and are discoverable at the Microsoft .NET Core Docker Hub repository. Each repository contains images for different combinations of the .NET (SDK or Runtime) and OS that you can use.
Microsoft provides images that are tailored for specific scenarios. For example, the ASP.NET Core repository provides images that are built for running ASP.NET Core apps in production.
