This article shows you the supported macOS versions and .NET Core dependencies that you need to develop, deploy, and run .NET Core applications on macOS machines. The supported OS versions and dependencies that follow apply to the three ways of developing .NET Core apps on a Mac: via the command-line with your favorite editor, Visual Studio Code, and Visual Studio for Mac.
It runs:.Net on the Mac. Well, there's Mono. It looks good and I hope it succeeds. But imagine what Microsoft could do if it got behind cross-platform.Net. All that research into the CLR on Free BSD must be there for a reason (BSD is the basis for Mac OSX). With a bit of effort, we could have Windows Forms apps running on the three most.

libgdiplus
.NET Core 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:
Visual Studio for Mac
You can use any editor to develop .NET Core applications using the .NET Core SDK. However, if you want to develop .NET Core applications on a Mac in an integrated development environment, you can use Visual Studio for Mac.

Incredible .NET IDE with the power of ReSharper! Rider is used across our entire dev team using Windows and macOS.

What is Rider?
JetBrains Rider is a cross-platform .NET IDE based on the IntelliJ platform and ReSharper.
Supports many .NET project types
Rider supports .NET Framework, the new cross-platform .NET Core, and Mono based projects. This lets you develop a wide range of applications including .NET desktop applications, services and libraries, Unity games, Xamarin apps, ASP.NET, and ASP.NET Core web applications.
Feature-rich and fast
Rider provides 2200+ live code inspections, hundreds of context actions and refactorings brought by ReSharper, and combines them with the IntelliJ platform's solid IDE features. Despite a heavy feature set, Rider is designed to be fast and responsive.
Cross-platform
As well as running and debugging multiple runtimes, Rider itself runs on multiple platforms: Windows, macOS, and Linux.
What's new in Rider
Xamarin support
Publish .ipa files to iOS devices and manage provisioning profiles for Xamarin iOS projects.
UI enhancements
The UI of the editor and debugger tabs, and the code completion popup is now clearer and more consistent.
Excellent Unity support
keeps getting even better.
New debugger goodies
A new way to star key variables while debugging and the floating icons for the Run to and Jump to Statement actions right in the code editor.
Enhanced C# support
Thanks to ReSharper, Rider 2019.2 supports new language features.
Solution Explorer updates
Solution folders can now be renamed.
Windows Forms designer
both third-party and 32-bit controls are supported.
Code Vision comes to F#
It shows you inferred types for functions, values, and members, and VCS author for declarations, right in the code editor.
Rearrange code
File Layout patterns can be modified via the XAML View right in Rider.
Code coverage of Mono
applications and unit tests on Linux, macOS, and Windows.
Commit from the Local Changes
There is no longer any need to go through a separate Commit dialog.
‘ASP.NET code-behind files’ generator
When you add a new control to an .aspx file, the generator creates the corresponding .designer.cs file.
Features
.net For Mac Osx
Code analysis
.net For Mac
Rider boasts 2,200+ live code inspections, with automated quick-fixes to resolve detected issues individually or in bulk. Solution-wide error analysis will monitor code issues and let you know if anything goes wrong, even in files that are not currently open.
Code editing
Rider's rich editor features different kinds of code completion and code templates, auto-inserting matching braces and import directives, quick info tooltips and gutter icons for inheritance navigation, context actions, and much more.
Refactorings
Most of ReSharper's 60+ refactorings are already available in Rider, and its 450+ context actions are all there. Rename, extract methods, interfaces and classes, move and copy types, use alternative syntax, and a lot more!
Unit test runner
Rider helps you run and debug unit tests based on NUnit, xUnit.net, or MSTest. You can explore tests, group them in different ways, break them down into individual sessions, see test output and navigate to source code from stack traces.
Debugger and more tools
Rider includes a debugger that works with .NET Framework, Mono and .NET Core applications, letting you step, watch, evaluate, and run to cursor. Other tools include a stack trace explorer, NuGet browser, and VCS and database support.
Databases and SQL
Work with SQL and databases without leaving Rider. Connect to databases, edit schemas and table data, run queries, and even analyze schemas with UML diagrams.
Navigation and search
Jump to any file, type, or member in your code base instantly, as well as quickly find settings and actions. Find usages of any symbol, or navigate from a symbol to the base and derived symbols, extension methods, or implementations.
Front-end technologies
Rider comes with JavaScript, TypeScript, HTML, CSS and Sass support built in. Take advantage of the refactorings, debugging, and unit testing capabilities included from WebStorm.
Extensibility
True to its roots, Rider supports a wide array of plugins developed for ReSharper and IntelliJ Platform. In addition to the bundled plugins (such as those for VCS, F#, and Unity support), plugins that support Markdown, .gitignore files, and Python scripts are available.
Rider for Unity
Rider comes backed up with Unity support.

Using Rider to write C# makes me happy. I have never seen code refactoring tools that actually work - always without exception. It's amazing when you can rely on it.

JetBrains Rider is the first tool I install after repaving my development machine.
Paint.net For Mac Download
I haven’t launched Visual Studio for months after I switched to JetBrains Rider.
Working with branches has never been so smooth since I started using Jetbrains’s Rider.
.net For Mac Os X
Dennis Doomen,
Continuous Improver at Aviva Solutions and author of Fluent Assertions
JetBrains Rider is my C# development tool of choice these days on both OS X and Windows. If you’re a longstanding ReSharper user, you’ll find it to be an almost seamless transition. I highly recommend the developer-friendly keystroke navigation and fine grained debugger support.

In Rider, I just focus on working with my code, as it should be, instead of fighting my IDE. Rider gave me back the joy in writing .NET code.
