to Allan-
The nested threading here is lacking ....
Thanks for clarifying.
So, what do i [think i will] gain by doing a clean install?
My experience, from 0S6 --> OS 10.6 is that update installers somehow make mistakes. I dont know what, and i dont knwo why, but they result in less-than-optimum installs. Sometimes.
When i do a clean install, onthe other hand (or the old archive and insatll, nto sur eif that still exists), i know that EVERYTHING is instaleld just as intended. None of this "that's the same rev, let it be" or "that wont cause any troubl;e, why remove it?"
I've seen many postings here too that people who are upgrading Mavericks over the top of older versions are having ahigher incidence of slow or weirdness than those who do a clean install. That reinforces my beliefs.
I know how hard doing really good undates is in my business, when thigns have to run 5-9s. Somehow i dont see the same leve of care here.
Do you disagree? Would you just upgrade over the top of SL? (actually, i may and see how it goes, i can alway go nuclear).
Always open to solid opinions.
