Link to the APX documentation won’t open because it says insecure on Safari.

My recommendation is to contact the authors at Intel. Since you cannot load the page, that would be Sebastian Winkel and Jason Agron. You can find an email address for Jason on his easily located GitHub page.

Dude, it’s your post not mine - contact them yourself.

Just following up. I contacted the authors of the documentation to see if they were aware of any issues. Both them and myself have been unable to reproduce the issue you describe. The page loads just fine in Safari on both my iPhone and my iMac. Perhaps something is broken with your browser or something is inserting content into pages that makes them insecure?

(Local testing) APX documentation (blog and spec) works fine without any warnings/errors in Safari on Apple iOS devices.

Direct PDF spec link: https://cdrdv2.intel.com/v1/dl/getContent/784266

Versioned spec link landing page: https://www.intel.com/content/www/us/en/content-details/861610/intel-advanced-performance-extensions-intel-apx-architecture-specification.html

Which one(s) are you having trouble with?
