safari - Tell iPadOS from macOS on the web

Question

The user agent of Safari on iPadOS beta is at this point exactly the same as Safari on macOS. Is there any other way to tell an iPad from a Mac?

When playing HLS video, the iPadOS agent seems to be:

AppleCoreMedia/1.0.0.17A5821e (iPad; U; CPU OS 13_1 like Mac OS X; en_us)

Answer 1

I'm using this test client side:

   if (navigator.userAgent.match(/Mac/) && navigator.maxTouchPoints && navigator.maxTouchPoints > 2) {
     ...must be iPad OS...

Since there's no official touch screen for Mac, it seems pretty safe. The actual value of maxTouchPoints on the iPad is 5, BTW.
