I'm setting up an address book (using OS X's Address Book) for my mother, who has macular degeneration disease and can't see small print well. She has a MacBook Pro running 10.6.8 and I have one running 10.8.5. I'm setting up her contacts on my computer and will export them and take them 75 miles up and import on her laptop. What I can't figure out is how to make the text larger. If I click Zoom, it just makes the page slightly larger. Is there a way to do this that I just haven't found?
