My disk needed what Disk Utility (booted from my CD) called a "minor repair." I repaired it and then went to repair permissions and it could not proceed, the error message saying that there were "No Valid Packages." Before all of this, I accidently mixed up my libraries and put things back in place as best as I was able. I still don't have Java access in my browser, and Flash wouldn't reinstall for some time, indicating that I didn't have proper permissions even though I am the admin of the computer, but otherwise things seem to be working fine and installs have otherwise worked fine. Should I do an archive install of OS X (10.4 on a C2D iMac) and then try to put things together again? Other ideas? I would like to avoid putting my machine in for service if possible. The disk now consistently passes Verify Disk though it is a bit noisier than before (though not noisy, before I never heard it). Any and all help appreciated. I also have Disk Warrior and some other major disk utility that I just received as a UB. Help!
