Let’s be clear.

The issue of Adobe’s support for Tagged PDF on the Mac is Adobe’s problem.

The issue of Apple’s support for Tagged PDF is Apple’s problem.

PDF is just PDF. There’s nothing Adobe-specific about accessible PDF.

That’s fair - but most Mac users use Preview to read PDF files.

The other way to look at it is this:

Apple - the richest software company on the planet - is unwilling (so far) to make Preview, their PDF viewer, work with accessible PDF.

I contrasted Apple and NVDA in this regard in a blog-post earlier this year:

This is 100% Apple’s choice - it has nothing to do with Adobe. No-one forced Apple to support PDF in Preview!

It does. OpenOffice will create a tagged PDF on the Mac. I just checked / confirmed.

Thank you for the reminder / correction.
