I am using a G4 Powerbook running 10.4.9. I installed the update this morning and had absolutely no problems and all is working well. As always I ran Repair Permissions after installation.

I am still wondering why a Security Update did not showup on Software Updates in my System Preferences when I ran it? Updates of this nature from Apple have always appeared there.

There have been a number of complaints about this update and I wonder if some are not running one of the wrong updates as three appeared. I went to the Apple site to download my update.
