How do you delete files from Macintosh HD? I cannot install a program because there is insufficient disk space?
I recently re-imported my iTunes music due to some malfunctions with my iPod. During the import, i kept getting messages saying my disk was getting full. Since my music in on an external, along with all my photos, I don't understand why the Macintosh HD was getting full. Now I can't install a new program. I'm not understanding why all the files are showing on my Mac when they are all on the external. How do I load the new program, since I can't seem to change the installation location to the external?
HELP!!
