After I install, I'm told that I have SP 5.2 and it is incompatible with my present OSX. Also, when I click on SP, nothing shows on my desktop. The icon in the dock has also disappeared. Which version of SP do I need? Also, after I clicked install, I didn't see "authenticate" which I guess woundn't show anyway. I backed up first so I can always restore what I had. jaybass
