Did not make a bootable backup drive when first installing mountain lion.  i do have time machine working an external drive.

Does Time machine work as an external bootable drive?


If not,  i think i read i could download the app again, and make a copy then but not run the setup again.

Is this necassry/useful for the future?

Everything is working okay now.


Also, this is a 2007 iMac running Intell with 4 GB memory- which I understood was the max.  S     Was suggested to me that I can actually increase to 6 GB memort. 

Is this correct?  Do i have to then get 2 3 GB memory cards to do so?  do they exist?
