Built for the browser-only machine
A Chromebook is the purest case for a web viewer: no Android subsystem required, no Linux container, no extension to sideload. The viewer is a single page that speaks Apple's Screen Sharing protocol directly from Chrome, decoding the framebuffer and painting it onto a canvas at full resolution.
Cheap hardware, real Mac
The heavy lifting — Xcode builds, Logic sessions, that 40-tab research profile — happens on the Mac at home. The Chromebook just moves pixels and keystrokes, which even a $150 one does happily. Touchscreen Chromebooks get the same touch-trackpad mode phones use; with a keyboard and trackpad it behaves like a desktop session.
Works on managed devices
Nothing to install means nothing for device management to block. If the Chromebook can browse the web, it can reach the viewer — the session is outbound HTTPS/WSS like any other site.
