According to the download website (http://boxen.math.washington.edu/home/sagemath/sage-mirror/osx/intel/index.html), the main difference between the two binaries is that one is geared towards Unix-style CLI use on OS X, and the other is meant to be a clickable Mac-style binary. The README in both disk images reflects this distinction.
However, having downloaded both disk images, I don't see a "sage" folder in the Unix-style CLI disk image. I only see the README, and "Sage.app" (technically a folder, but not named "sage"), so the first-level directory layout looks the same, and double-clicking on Sage.app from the Unix-style CLI disk image starts Sage without having to resort to any of the additional steps for launching Sage from the README. Obviously, the two disk images are different; they have different checksums, and different file sizes. Could someone explain the differences in a little more detail? -- You received this message because you are subscribed to the Google Groups "sage-support" group.
