Apple's Snow Leopard introduced Menlo, a modified version of the Linux font DejaVu Sans Mono, as its new monospace typeface. The author, dissatisfied with several design choices in Menlo (particularly the slashed zero and the oddly-proportioned lowercase L), used FontForge to create a custom variant called "Mensch" with about a dozen tweaks including a circular zero, friendlier punctuation marks, larger angle brackets, and improved letter distinctiveness. The modifications maintain the open-source spirit of the original Bitstream Vera license while optimizing the font for code readability and aesthetic preference.
