Ok I have an old iMac with a 250g hardrive. As you can imagine over the years it has filled up and slowed down. I upgraded the ram a year ago and it seemed to be working like a champ. Then when I saw it was just about full I bought a 1Tb external hard drive. the Ehd drive has the 250g of info from my iMac on it, but my Mac is still full. For some reason I have the habit of duplicating things and my 15,000 iTunes library and over 10,000 pics seem larger than they are. How the heck do I put all that music and pics on my EHD and free up all this space on my iMac while not changing the way I know how to use my Mac. ex. When I plug in my iPad, wife's iPhone, my iPhone, my 2 kids iPod touches, etc.... Will it still find everything even though it's on the EHD? I'm very close to buying a new iMac, but not sure if it's necessary. Lastly what happens to my aperture program, office and other programs I don't have discs for? Please keep the Mac lingo for a pro, I need to be spoon fed when it comes to computers Thank you all in advance.
