Apple seeds Mac OS X 10.4.3 8F40
The combo update's still around 100 MB and has one known issue, which brings it much closer to being finished than the last couple of builds, but it means that there's at least going to be another one, hopefully with no known issues at all. The update is said to provide support for not only the new iMacs, but also the dual-dual PowerMacs and new PowerBooks that should come out at the end of October, possibly as early as next week.
