Several sites are predicting October 26 as the release date for Mac OS X 10.5 (Leopard), which I think is pretty accurate. That date fits in nicely with Apple’s usual release schedule, which always seems to be the last Friday of the month.
| OS X Version | Release Date |
| 10.0 | March 24, 2001 |
| 10.1 | September 25, 2001 |
| 10.2 | August 24, 2002 |
| 10.3 | October 24, 2003 |
