Apple Garamond

I never realized that the font Apple used for almost twenty years, starting in 1984, was a custom-condensed version of Garamond, halfway between Garamond and Garamond Condensed.

From Wikipedia:

Upon the introduction of the Macintosh in 1984, Apple adopted a new corporate font called Apple Garamond. It was a variation of the classic Garamond typeface, both narrower and having a taller x-height. Specifically, ITCGaramond (created by Tony Stan in 1977) was condensed to 80% of its normal width. Presumably, Apple felt that the existing ITC Garamond Condensed, at 64%, was too narrow. Bitstream condensed the font and subtly adjusted the stroke widths and performed the hinting required to create a font that was then delivered to Apple as Postscript font apgaram.
