I am having a prob with my dvd player. ON the apple site they suggest a fix:
You can fix this by renaming the old framework.
In Terminal, type the following two lines (pressing the return key after each line):
sudo mv HIServices.framework HIServices.framework.old
Be aware that this will ask you for your administrative password.
So I open the program and try to type the two lines, but after the first I hit return and it just repeats my computer name and then says "command not found" How do I enter text so that it accepts it. Sorry for the stupid question.,
