I didn't use time machine to back up my drive afterward, and now I can't reinstall and I don't know how to uninstall snow leopard. I tried to use disk utility to restore, but I didn't back anything up, so it didn't work. What can I do to get terminal back? And is there any way to see if I lost any other applications? Also, the reported applications that I was supposed to receive in my dock from the upgrade isn't there is it because my mac is the 2008 white plastic mac?
