This is an old problem, discussed and allegedly solved two years ago. I've migrated from an old iBook to a new MacBook and now I keep getting a dialog box asking over and over again for my Symantec keychain password. None of my passwords work. I have deleted the Symantec keychain from the Library and followed the solution posted here but it leads to a blank page. I can't even delete all traces of Norton from my computer ... still keep getting the dialog box. Help please.
