1) How do I make a hard copy of the install disk for future disk utility uses etc ?
OS X downloaded from the AppStore gets saved into your Applications folder. Although I can't remember if the installer cleans itself up after the upgrade, I don't think it does but if it does, you'll need to redownload from the App store (from memory its as simple as browsing your history and holding down the option key).
You've got two choices from here :
- Backup the installer App package itself through simple drag & drop
- Backup the ISO disk image contained within the App package. In order to do so you need to "explore" the App and dig out the ISO from its innards (Show Package Contents -> Contents -> SharedSupport -> InstallESD.dmg)... then you can either backup the ISO through drag & drop or burn the image to disk using Disk Utility if you want something bootable.
2) where has the access to 'library' gone ? That is the library that gave access to all things.
As in "library/Application Support" and all that jazz ? Its still there, just hidden by default.
Try Go -> Go to Folder (or shift-command-g) -> "~/Library" (or "/Library" for the system wide one).
No doubt there's a way to turn off the hiding, just I've never used it as I just go to the command line when I want to do serious stuff (a quick Googoo suggests the answer might be
defaults write com.apple.finder AppleShowAllFiles YES followed by HUP'ing the Finder to refresh ..... again, at your own risk as I've never tried it)
