With the release of macOS Sonoma back in 2023, Apple introduced a new High Performance screen sharing feature for the Mac’s native Screen Sharing application. This mode dramatically increases the usefulness of screen sharing. Responsiveness is improved, stereo sound output from the native Mac is enabled, and HDR is available, among other features.
Users working with professional apps like Final Cut Pro or Logic Pro will find that High Performance screen sharing significantly enhances the experience using those apps via a Screen Sharing connection with few downsides.

High Performance screen sharing requirements
To use High Performance screen sharing, both computers must be Apple Silicon Macs running macOS Sonoma 14 or later. In my example, I’m connecting my 16-inch M4 Pro MacBook Pro to my headless M4 Mac mini, mounted under my desk, using Sonnet’s MacCuff mini (review).
The second most important requirement for using High Performance screen sharing is a high-bandwidth, low-latency network connection. Apple recommends a wired network of at least 75Mbps for a single 4K display. In my video example, I’ve set up a gigabit Ethernet bridge between the Mac mini and my CalDigit TS5 Plus Thunderbolt hub (review), which provides more than enough bandwidth to meet Apple’s requirements.
Note: Communication on UDP ports 5900, 5901, and 5902 must be available for both Macs.
