All other email clients render the text, but not in Apple Mail 9 or 10. Images show, and all of the styling etc, but just no text.

I am using Open Sans via google fonts, as mentioned the font shows everywhere else (where its supported anyhow).

A question like this was posted 4 months ago ( but has no replies (apart from one that isnt helpful).

Is this an issue you are aware of, familar with, seen before?

Addtionally, if i remove the link to the web font, then text of course shows normally. Here is my link, nothing unusual:

<link rel="stylesheet" type="text/css" href=',400,600,700,800'>
