When I tried to install the Mac OS X 10.4.7 update on my MacBookPro, the machine froze when the update was almost finished and left the machine unable to boot. When I started up in single user mode, it showed that launchd couldn’t be started which prevented it from booting completely. I ended up doing an archive & install from the original MBP system DVD and I now pretty much have everything back to normal.
