NDI Tools for Mac vs Windows
Introduction
NDI Tools is available for both Windows and macOS, but the platforms do not offer identical utilities or the same feature depth. Both operating systems include the core tools needed to configure, route, and monitor NDI streams. However, several applications are platform-specific, and even shared tools may differ in implementation or capability. Understanding these differences is important when designing workflows, especially in environments that rely on remote production, GPU acceleration, or advanced monitoring.
Core Tool Availability by Platform
NDI Tools for Windows includes:
NDI Tools for Mac includes:
The overlap centers on configuration and routing utilities. The main differences are in capture tools, monitoring utilities, and virtual camera functionality.
Windows-Exclusive Tools and Capabilities
NDI Bridge enables remote NDI workflows across WAN or VPN connections. It supports H.264 and HEVC transcoding, alpha channel transmission, encryption, and port forwarding. It also includes KVM functionality for remote control scenarios, which makes it well suited for distributed production environments.
Screen Capture HX provides GPU-accelerated capture with integrated compression. Users can define bandwidth presets, control resolution and frame rate, and use H.264 or HEVC encoding to optimize network performance. KVM remote control is also supported.
Webcam Input allows NDI sources to appear as standard webcam devices in conferencing applications. It includes system tray controls, audio channel grouping, customizable output resolution, and dedicated audio and video configuration tabs.
macOS-Exclusive Tools and Capabilities
On macOS, screen capture is handled by Scan Converter instead of separate standard and HX variants. Scan Converter captures either a full desktop or a single application using macOS native screen capture integration. Because it operates within the macOS privacy framework, users must grant the appropriate system permissions. Unlike Windows, individual monitor capture in multi-display environments is not supported.
Virtual Input functions as a system camera extension. It requires Camera Extension approval in macOS System Settings and operates within Apple’s extension management framework. As a result, deployment and troubleshooting may involve system-level permissions rather than application-level configuration.
Video Monitor allows users to view NDI sources and includes PTZ control and recording functionality. It also supports low-bandwidth mode and web-based control through a QR code or IP address. It does not provide the same depth of overlays, routing, or advanced monitoring features as Windows Studio Monitor.
Monitoring Tool Comparison
Windows includes Studio Monitor, which provides overlays, VU meters, safe area guides, alpha channel display, flip controls, lowest-latency mode, picture-in-picture, USB joystick PTZ control, and NDI video output routing. It is suitable for both previewing and technical validation.
macOS includes Video Monitor, which supports PTZ control, recording, low-bandwidth mode, and web-based remote control. However, it offers fewer overlay, routing, and advanced monitoring features than its Windows counterpart.
Screen Capture Implementation Differences
On Windows, Screen Capture supports full desktop capture and lets users define a region of interest. Screen Capture HX adds GPU acceleration, compression, and bandwidth management.
On macOS, Scan Converter captures either the full desktop or a selected application using native system integration. Capture behavior is governed by macOS privacy permissions, and individual monitor capture in multi-display setups is not supported.
Shared Tools Across Both Platforms
Both Windows and macOS include Access Manager, Router, Test Patterns, and Discovery. Access Manager allows configuration of NDI groups and Discovery Server settings. Router enables routing of up to 64 sources to 64 destinations with preset recall functionality. Test Patterns generates calibration patterns, custom images with alpha channel support, and audio tones. Discovery allows users to view active NDI senders and receivers and configure Discovery Server IP and port settings.
System Integration Differences
On Windows, users benefit from startup integration options, GPU acceleration for Screen Capture HX, and expanded UI-based configuration.
On macOS, applications operate within Apple’s privacy and extension frameworks. Virtual Input requires camera extension approval, running multiple Video Monitor instances requires a Terminal command, and audio routing is tied to macOS system settings, often requiring third-party virtual cable software.
Summary
Both Windows and macOS versions of NDI Tools provide the core utilities needed for NDI configuration, routing, and monitoring. Windows offers a broader feature set for remote workflows, GPU-accelerated capture, advanced monitoring overlays, and granular virtual webcam configuration. macOS provides streamlined native integration within Apple’s ecosystem but operates within stricter system-level permission and extension requirements.
Platform selection should be guided by workflow complexity, monitoring requirements, remote production needs, and network architecture, rather than by assumptions of feature parity.
