Mac Rumors has posted an article which reveals that Mac OS X Leopard seed (9A559) has two remaining “issues” of which one was simply a test case for a new feature.

The actual bug is about “Archive installs” from Tiger to Leopard on PowerPC machines, and appears to be a true outstanding issue.

This means that it looks like OS X 10.5 is getting very close to release. It is meant to be released in October (which of course is only a few days away). Like all major software releases it needs to be shipped to manufacturing for mass production. This normally means the software frozen a few weeks before the software hits the shelfs.

Of course, there isn’t only 1 bug left in OS X 10.5, there are thousands but that is true of all software including Windows, Linux and OS X. That is why there will be OS X 10.5.1 and we are all waiting for Vista SP1.
