I am curious as to what typeface was used on the Mac OS 9 & early Mac OS X boxes. Where it reads "Installing Mac OS 9". The slopes of the letters are slightly different than any font that comes pre-installed on a modern Mac, and the 9 is obviously quite unique looking. If anyone is aware of the typeface name please let me know. Danke.

It was designed for Apple:
Hoefler Text is a contemporary serif Antiqua font that was designed for Apple Computer to demonstrate advanced type technologies. Hoefler Text was created to allow the composition of complex typography; as such it takes cues from a range of classic fonts, such as Garamond and Janson. Designed by Jonathan Hoefler in 1991, a version of Hoefler Text has been included with every version of Mac OS since System 7.5.
The easy way is to click on the "Aa" on the right side of address window once you are in reader mode already, and choose font and background colors :)

The font being used is Apple Garamond. This was used by Apple as one of its corporate fonts since the Mac was first launched in 1984 up until the early 2000s.
