Would you use remote software to control your desktop computer from your phone or tablet?
The open-source utility Sill enables users to remotely control macOS applications directly from iPhones and iPads. This tool allows operators to stream desktop windows to mobile devices over local networks or VPNs, provided the host Mac runs macOS 14 or later.
Why it matters
For small business owners, this utility offers a cost-free method to access desktop-bound software while away from the office. It facilitates mobile workflows by allowing remote interaction with full macOS environments via touch or external peripherals.
The current Sill implementation mandates macOS 14 or later and iOS or iPadOS 17 or later to function, a significant update from version 0.3.1 which lacked security protections. Connections now utilize TLS 1.3 encryption to secure remote sessions between devices.
The details
The application leverages ScreenCaptureKit for window capture and VideoToolbox for HEVC encoding to maintain visuals across devices. Operators can bridge their mobile interface to the host through local networks, direct wireless, or VPNs. Once paired, input commands from touchscreens, trackpads, keyboards, or Apple Pencils are translated back to the host Mac.

Market Landscape
This development leverages Apple's ScreenCaptureKit to bring desktop-class control to portable hardware. It marks a shift in how small-scale operators manage remote access, mirroring the capabilities of paid enterprise VNC solutions through open-source infrastructure.
Business operators should verify that their workstation hardware is updated to macOS 14 or later before attempting to integrate this tool into their remote workflow. Note that the software does not support audio transmission and limits clipboard syncing to text, which may impact tasks requiring multimedia or file sharing.
The takeaway
Using open-source tools for remote access can streamline mobile office operations at no cost, provided encryption standards are strictly maintained. Operators should prioritize pairing their devices and monitoring the host computer to ensure it remains awake during critical remote access windows.
