Notes on Beam, working across several Macs, and what we are building.
-
Run a headless Mac mini and see its windows
Beam shares one window at a time, or a whole display when you pick one. Then make sleep and reboot reliable.
-
Use one Mac app without sharing the whole desktop
Beam puts one app window from another Mac on your desktop, with direct input, crisp text, optional audio, and no whole-desktop viewer.
-
Test Mac layouts beyond your screen
Test macOS app layouts just before and after they change, then use Beam to resize the window into shapes the other Mac can fit more easily.
-
When a shared Mac window disappears
Minimize, hide, close, and Spaces affect Mac windows differently. See what each action means while you work with a beamed window.
-
Give another Mac’s app your whole ultrawide
Let an app from another Mac fill the space your work needs. Beam resizes the real source window and streams it crisply onto your ultrawide.
-
Nothing goes through a server
Your Macs talk to each other directly, over your own network or your tailnet. There is no account, no relay and no cloud. This is what leaves a Mac when you use Beam, and what does not.
-
Running a headless Mac mini from your desk
A Mac mini in a closet with no display and no keyboard is a good place for builds and agents. Here is how to set it up so its windows open on the Mac you are actually sitting at.
-
A window, not a screen
Screen sharing gives you a picture of a desktop. Beam gives you the window itself, on your desktop, at its own size, in your ⌘ Tab. Here is why that distinction is the whole product.
