They don’t *have* to be the same size, but newer Macs with Intel Core 2 Duo processors (or older dual-proc G5s) prefer it. But if one stick isn’t registering, it’s either in wrong or the wrong kind of memory. Try shutting down and reseating the RAM.
The easiest place for Mac owners to go is http://crucial.com. Download Crucial’s little, easy system scanner, and let it tell you what to order. Their RAM is reliable and a fine value.
