About this project

TargetBridge revives the lost Target Display Mode by enabling Intel iMacs to function as external displays for Apple Silicon Macs. This free, open-source solution uses Thunderbolt Bridge technology, allowing seamless 5K streaming over a direct connection, making tech compatibility easier than ever.

TargetBridge enables the use of an Intel iMac as an external display for Apple Silicon Macs through a direct Thunderbolt connection, restoring the functionality lost since the removal of Target Display Mode in 2014. This open-source solution allows seamless streaming of screens up to 5K resolution, catering to users looking to optimize their workspace without the need for additional hardware.

Key Features

High-Resolution Streaming: Supports various stream profiles including 5K, making it ideal for graphic design, video editing, and other high-definition tasks.
Multi-iMac Support: Upcoming releases will allow multiple Intel iMacs to serve as receivers from a single Apple Silicon Mac, enhancing versatility for multi-monitor setups.
Automatic Discovery: An automatic receiver discovery feature via Bonjour simplifies set up, allowing users to connect devices effortlessly.
User-Friendly Interface: Intuitive dashboard for managing multiple sessions provides a streamlined experience for users.

Stream Profiles

Choose from multiple streaming options:

- Standard: 2560 × 1440
- Smooth: 2560 × 1440 @ 60fps
- Smooth+: 3200 × 1800 @ 60fps
- Crisp: 3840 × 2160 @ 48fps
- 5K: 5120 × 2880 @ 48fps

These profiles ensure that whether users are mirroring their display or using an extended desktop, visuals remain sharp and responsive.

Usage Scenarios

Extended Desktop: Utilize the iMac as an extension of the desktop for more workspace. Simply select Extended display on the sender Mac. This allows for efficient multitasking and a more organized desktop layout.
Mirrored Display: Ideal for presentations or collaborative environments where the same screen needs to be viewed by multiple users.
