Awwww, but what if I wanted to throw all caution to the wind and live 
No backup, just install and go,…and hope for the best!! Check things?? 
Pfftt,…nah,….I’m sure all will be good. :) hehehe.

Ok, I joke. :) hehe.
Though it was on my “test iMac” and if I have to erase it from scratch, nothing 
lost :)
Unlike a friend of mine who always tested the betas (as he’s a developer) on 
his main machine! Then wondered why things didn’t work. lol. But he loved 
tinkering to get it right. Me,..I just want it to work. :) And with a safety 
net. :) hehe. You can never have too many backups.
In saying that, all has been good so far (touch wood).

Sorry, couldn’t resist,…hehe :)

Kind regards
