Sill is a Mac menu bar app that streams your desktop or individual app windows to an iPhone or iPad for remote control and viewing.
What is Sill?
Sill is a native Mac streaming app for viewing and controlling a Mac from an iPhone or iPad. It is designed for people who want quick access to Mac apps, windows, and desktop content from another Apple device without setting up a full traditional remote desktop workflow. Sill can stream a single window or the entire desktop, supports touch input and external keyboards on the mobile side, and offers connection modes such as wired USB, local Wi‑Fi, direct wireless, and remote access through a user-managed VPN or port forwarding setup. The app also includes options for virtual display use, window switching, app launching, and stream quality controls. Published by NOAH WILLIAM SAFFER, it fits best for Apple users who want a lightweight Mac companion for mobile access and control.

Safety overview
Status: Mostly safe
Sill is a legitimate remote-access and streaming utility, so it may request permissions that are normal for this kind of app, such as Screen Recording, Accessibility, or network access. Those permissions allow it to capture your Mac’s display and pass input from your iPhone or iPad back to the Mac. Keep it only if you use its remote viewing features, and review its remote-access settings carefully if you enable connections beyond your local network.
Recommendation: Keep Sill if you use your iPhone or iPad to view or control your Mac. If you do not use those features, you can remove it to reduce background menu bar activity and revoke its permissions afterward in macOS settings.
