Macintosh OS X 10.3 Panther: no Microsoft web fonts?: Ho ho, you may build a better OS, but you can’t have our fonts! Try to imagine a world without verdana, Dave, just try.
“I’m not sure about this, but Apple may have stopped including the Microsoft core web fonts in the Panther 10.3 install. Ever since Explorer came out on the Mac, the install has included Microsoft’s now-ubiquitous web fonts, including the ever-popular Verdana, Trebuchet, Arial, and Georgia. But my Archive & Install of 10.3 has the web looking very different, as Verdana, Arial, or Trebuchet fonts render as Helvetica, Georgia as Times… Take a look at a site like Amazon, which uses Verdana all over; in Safari on 10.3, you get it as Helvetica. The bummer is that Helvetica renders smaller than Verdana, making the small type sizes a little less legible.”
