Acoustic guitars aren't generally MIDI devices, but your computer should recognize that something is connected to the microphone jack. Mic jacks are amplified so you wouldn't want to amplify the guitar before connecting it to the mic jack. Laptops don't normally have Line In ports, but they are unamplified.

You'll need to have a battery in your guitar, usually there's a slot in the top of the body with a button and LED you can use to test if it's got enough charge. Once that's working you should also ensure that the cable is working and that you properly convert from stereo to mono or vice versa if need be. I would suspect both ports (guitar + computer) are mono so in that case you would ensure you're using mono cables and that the size converter is also mono to mono. However it appears that (some) Macbooks have combined ports, so in that case it's probably stereo. Perhaps that post can help you figure it out.

Then ensure OSX is detecting the microphone. I don't use a Mac so unfortunately I can't help with that, but there should be Sound Properties or something similar in the OS settings where you can view input levels and so on.
