Some programs haven't been installed
Execuse me.
When I bought my Mac mini and there were several programs installed in the OS X pre-installation.
Yesterday, during the boot, I kept pressed CMD + R, I have erased my disk and then installed all over again due few problems. But now, several programs pre-installed aren't installed anymore, such as Pages, Numbers and Keynote.
I know I can download them in App Store, but I'd just like to know if this installation through that way I did is a very "raw" installation, differently from that that comes pre-installed once you buy the computer, and not a bug or whatever! Thank you.
Mac mini, OS X Mavericks (10.9.2)
