The last upgrade rolled out for operating system Mac OS X Leopard was back in December, with security update 10.5.1. However, many failed to notice that Apple quietly released a build to developers during the recent Macworld Expo.

At this point, we have to say that this is one of the most massive update Apple has made that easily comes to mind. Roughly, 10.5.2 update comes with 100 bug fixes tackling more or less 40 applications.

But before we give you the list, Apple fans have also found out two more changes that have not been incorporated in the list provided by Apple. These include to share optical drive with other computers and to use a networked volume as Time Machine backup device.

Now, without any ado, here is the seed notes for Mac OS X Leopard 10.5.2:
