Fleet Readiness Dashboard

An interactive simulator for an IT admin: feed in your fleet's macOS distribution (or pick a preset), set a refresh velocity, and see how many seats need upgrading, by when, and how the line crosses the Chrome 151 cut.

Simulator, not a real reader. In production you'd pipe macOS version distribution from MDM (Jamf, Kandji, Intune) or via UA-CH on a sign-in page. Use the live probe in macOS Support Checker for a real read of the device you're on.

code (admin probe)

// Server-side: on a sign-in page, request high-entropy UA-CH
// and shard your beacon by platformVersion. Then plot the
// histogram in your BI tool.

const hints = await navigator.userAgentData.getHighEntropyValues([
  "platform", "platformVersion"
]);
if (hints.platform === "macOS") {
  const major = parseInt(hints.platformVersion.split(".")[0], 10);
  beacon({ name: "macos_major", value: major });
  // ...later, count distinct devices per major and divide by
  //    your fleet size to plot the readiness curve.
