What is Apple doing to address the needs of the sight-impaired?

As many of you know, Apple's MAC OS X User Interface utilizes small fonts. For example, look at the top-most bar of your screen--the menu bar. Even the Apple icon is tiny. Next is the Bookmark toolbar.

Its fonts are almost indistinguishable to those of us who are sight-impaired.

A poster with the username i joel posted back in 2007 peading with Apple on behalf of sight- and movement-impaired patients/clients to just make the Finder bar larger and increase the font size so that his people could see the screen content better.

Apple had a golden opportunity then to address this issue and champion the needs of disabled users worldwide. Leadership was within Apple's grasp.

Sadly, I found i joel's post in this 'support' community--archived (kicked to the curb, sent to the dust heap). As far as I can tell, sitting here 5 years later, squinting to try to read my 2012 Mac OS X (Lion) menu bar, Apple has failed to address i joel and I'm sure many others straining with this same issue.

5 years!

The last post in response to i joel's 2007 thread was, "get Bootcamp and run Windows on your Mac."

Then the thread fell silent, and I stumbled over it in the archives in 2012.

Not exactly a ringing endorsement of Apple's product nor of their interest in helping their customers!

But wait! Could I be mistaken? Could someone enlighten me as to any effort that Apple has made over the last 5 years to make their product more accessible to disabled persons (sight-impaired, movement-impaired)?
