I'm running 10.6.8, trying to update to Mavericks.  I ran the installer, got an error.  (Sorry, I don't remember the specific error.)  I used disc utiility to enable journaling.  Still had a problem, but installer did get as far as listing recently used power pc apps that will no longer work.

 

Did some research, and it looked like it might be an issue with partitions.  (I had a techtool edrive partition.)  I removed that.  Ran disc utility to Repair disc.  Installer says "this disc cannot be used to startup your computer".  Huh.  Surprising since the disc is being used to startup my computer, but okay.

 

Did some more research, restarted, repaired disc again, repaired disc permissions.  Still getting the same error.  I'm stumped.  Any ideas?
