Incomplete App Download

If you are currently downloading an app or there’s a download that is incomplete, the modified date for said file is a clever easter egg that references the history of the Mac.

Although it can be tough if you have a speedy internet connection, try right-clicking and hitting Get Info on an in-progress or incomplete download. The modified date should say January 24, 1984 — which is the exact day that Steve Jobs first introduced the original Macintosh.
