C# IronPDF Support for macOS with .NET Core
IronPDF supports macOS for .NET Standard Libraries, Core applications, and .NET 8, 7, 6, & 5 projects without dependencies. Create PDFs on Mac and deploy cross-platform to Windows, Linux, and Mac environments. This native support enables HTML to PDF conversion directly on macOS without platform-specific modifications.
Quickstart: Set Up IronPDF on macOS
- Identify your Mac processor type (Intel or Apple Silicon)
- Install the appropriate NuGet package:
- Intel Macs:
Install-Package IronPdf.MacOs - Apple Silicon:
Install-Package IronPdf.MacOs.ARM - Both: Install both packages
- Intel Macs:
- Start using IronPDF without code changes
- Deploy to any platform (Windows, Linux, Mac)
```cs :title=Program.cs using IronPdf;
// Create a PDF from HTML on macOS var renderer = new ChromePdfRenderer(); var pdf = renderer.RenderHtmlAsPdf(""); pdf.SaveAs("macos-example.pdf");
// Convert a URL to PDF var urlPdf = renderer.RenderUrlAsPdf("https://example.com"); urlPdf.SaveAs("website.pdf");
.NET Framework projects on macOS are not supported as they use Xamarin implementations rather than official .NET runtime releases. Use [.NET Core or .NET 5+ projects](https://ironpdf.com/get-started/installation-overview/) for modern development.
IronPDF supports all macOS versions out-of-the-box as of January 2020 without dependencies. Start immediately with [creating PDFs from HTML strings](https://ironpdf.com/how-to/html-string-to-pdf/), [converting URLs to PDFs](https://ironpdf.com/how-to/url-to-pdf/), or working with existing PDF documents.
No code changes are required to support Apple users or developers. Deploy Mac-developed projects to Windows, Linux, and Mac environments by adding appropriate binaries for each platform. See our guides for [Windows deployment](https://ironpdf.com/get-started/windows/) or [Linux deployment](https://ironpdf.com/get-started/linux/).
On macOS, multithreaded PDF rendering support cannot yet be implemented due to Chromium Embedded Framework limitations. For concurrent PDF generation needs, see our [async PDF generation guide](https://ironpdf.com/how-to/async/) for alternative approaches.
Many .NET developers prefer developing on macOS using *Visual Studio for Mac* and *JetBrains Rider*, making cross-platform support essential for modern .NET development.
## How Do I Configure IronPDF for My Mac's Processor Type?

<!-- Description: Screenshot showing the step-by-step process -->
Apple used Intel processors until 2020, when they began launching Macs with Apple Silicon processors. IronPDF provides optimized packages for both architectures.
- For Intel Macs, install the [IronPDF for macOS on Intel](https://www.nuget.org/packages/IronPdf.MacOs) NuGet package.
- For Apple Silicon Macs, install the [IronPDF for macOS on Apple Silicon](https://www.nuget.org/packages/IronPdf.MacOs.ARM) NuGet package.
- To support both Intel and Apple Silicon Macs, install both the [IronPDF for macOS on Intel](https://www.nuget.org/packages/IronPdf.MacOs) and [IronPDF for macOS on Apple Silicon](https://www.nuget.org/packages/IronPdf.MacOs.ARM) NuGet packages.
```cs
// Example .csproj configuration for universal Mac support
<ItemGroup>
<PackageReference Include="IronPdf" Version="*" />
<PackageReference Include="IronPdf.MacOs" Version="*" />
<PackageReference Include="IronPdf.MacOs.ARM" Version="*" />
</ItemGroup>How Can I Check My Mac's Processor Type?
Click the Apple menu, select "About This Mac," and check the processor information. Intel processors show names like "Intel Core i5" or "Intel Core i7." Apple Silicon processors display as "Apple M1," "Apple M2," or newer. Alternatively, use Terminal command uname -m which returns x86_64 for Intel Macs and arm64 for Apple Silicon Macs.
Which NuGet Package Should I Choose for My Project?
Package selection depends on deployment needs. For personal development, install only the package matching your processor. For team environments with mixed hardware, install both packages—IronPDF automatically selects the correct runtime. For distributed applications, include both packages to ensure compatibility across all Mac hardware. This follows principles in our NuGet installation guide.
What Happens If I Install the Wrong Package?
Installing the wrong processor-specific package causes IronPDF initialization failure with a clear error message indicating architecture mismatch. The application throws DllNotFoundException or similar platform-specific errors. This won't damage your system—install the correct package or both packages to resolve. For deployment troubleshooting, see our quick troubleshooting guide.
What Hardware Specifications Does IronPDF Require on macOS?
IronPDF uses Chromium to render HTML to PDF with pixel-perfect accuracy matching Chrome's print feature. Hardware specifications primarily support the Chromium engine, which requires most computing power.
- Minimum: 1 Core & 1.75 GB of RAM
- Recommended: 2 Cores & 8 GB of RAM or above
For complex PDFs or high-volume processing, implement PDF compression techniques to reduce memory usage and improve speed.
Why Does IronPDF Need These Specifications?
The Chromium rendering engine requires significant resources to process HTML, CSS, and JavaScript like a web browser. Converting HTML to PDF launches a headless Chrome instance that interprets styles, executes scripts, loads images, and renders output. This ensures pixel-perfect PDFs but demands adequate CPU and memory. Complex documents with heavy JavaScript, multiple images, or intricate layouts require more resources. See our performance assistance guide for optimization tips.
How Does Performance Compare to Windows Systems?
macOS performance matches Windows systems with similar hardware. Apple Silicon Macs often outperform due to unified memory architecture and optimized CPU design. M1 and M2 processors excel at PDF rendering, surpassing Intel-based systems in speed and energy efficiency. However, lacking multithreading support on macOS may impact high-volume server applications. For performance comparisons and optimization strategies, see our rendering options documentation.
Can I Run IronPDF on Older Mac Models?
IronPDF supports macOS 10.12 (Sierra) and later, compatible with Macs from approximately 2010 onwards. Older models with limited RAM or slower processors may experience performance limitations. For Macs with 4GB RAM or less, close unnecessary applications during PDF generation and process smaller documents. Consider upgrading to 8GB RAM for professional use. Legacy Intel Macs before 2015 may need optimization techniques from our native vs remote engine comparison for acceptable performance.
Frequently Asked Questions
How do I install IronPDF on macOS for .NET Core development?
To install IronPDF on macOS, first identify your Mac processor type. For Intel Macs, install the IronPdf.MacOs NuGet package. For Apple Silicon Macs, install IronPdf.MacOs.ARM. You can install both packages to support both architectures. IronPDF works natively on macOS without any additional dependencies.
Can I develop PDFs on macOS and deploy to Windows or Linux?
Yes, IronPDF enables full cross-platform development. You can create PDFs on macOS and deploy the same application to Windows, Linux, and Mac environments without code changes. Simply add the appropriate IronPDF binaries for each target platform during deployment.
What .NET versions does IronPDF support on macOS?
IronPDF supports .NET Standard Libraries, .NET Core applications, and .NET 8, 7, 6, & 5 projects on macOS. However, .NET Framework projects are not supported on macOS as they use Xamarin implementations rather than official .NET runtime releases.
How do I create a PDF from HTML on macOS using C#?
Use IronPDF's ChromePdfRenderer to create PDFs from HTML. Simply instantiate the renderer and call RenderHtmlAsPdf() with your HTML content. For example: var renderer = new ChromePdfRenderer(); var pdf = renderer.RenderHtmlAsPdf("Hello from macOS!"); pdf.SaveAs("macos-example.pdf");
Are there any limitations when using IronPDF on macOS?
The main limitation is that multithreaded PDF rendering is not yet supported on macOS due to Chromium Embedded Framework constraints. For concurrent PDF generation needs, IronPDF provides async PDF generation methods as an alternative approach.
Which development tools work with IronPDF on macOS?
IronPDF works seamlessly with popular macOS development tools including Visual Studio for Mac and JetBrains Rider, making it ideal for .NET developers who prefer developing on macOS.
