At about the same time that I started to download and install 10.4.2, a major storm decides to roll through the area. The last that I saw the status, it said "Installing Mac OS X Update" next thing I know, the electricity blinks, and bye bye computer! I quickly powered it back up, and it started (thank god) but everything is TERRIBLY slow; however, in the "About This Mac" it shows as 10.4.2 I'm afraid that it wasn't completely finished installing when the electricity went. I repaired permissions and there were TONS that needed fixed (unusual for my machine) Is there any way that I can force to reinstall 10.4.2, because Software Update says my computer is up to date. Please, someone help me!
