Apple appears to be finishing up work on Mac OS X 10.5.6, an update that is supposed to fix over 100 bugs and glitches. While an official release date is uncertain, MacRumors is reporting that it might come as soon as this Friday.
Apple has seeded yet another build of Mac OS X 10.5.6 (9G55) to developers. This latest seed reveals no known issues and has addressed a few outstanding issues.
Beyond this, we have heard that Apple has started distributing this particular seed internally outside of the usual developer circles. This would indicate that this is the final version of Mac OS X 10.5.6 before public release. We had also heard unconfirmed whispers that the new version would be made available to the public on Friday, and this new information certainly makes that plausible.
OS X 10.5.6 is slated to be the most comprehensive OS update in terms of system maintenance since Leopard was first released in October of 2007. When released, it will be available as a free update to Mac users currently running OS 10.5.
