Apple Watch Series 8 will only unlock one Mac, not both.

Is anybody else disappointed?

I just bought an Apple Watch Series 8.

I could set my old Series 4 to automatically unlock both my iMac and my MacBook Air.

But Apple Support tells me the new Series 8 will only unlock one Mac, not both, so I have to choose.

Does anybody have a workaround?
