can someone tell me the screwdriver i need to take the back of the macbook off... all my screwdrivers do not fit. i need to insert new ram and this is why.
Should be a Philips 00 driver - look for a "precision screwdriver kit" at your local hardware store. A pocket knife works in a cinch, but you run the risk of damaging the screws.
Here's some repair guides you can check out too. I think your model is the A1278, if I'm not mistaken.
Yes, they are the same. A Philips #000 should work fine for most of the screws - I know that on mine, the external body screws were slightly too large for the #000, so I prefer the #00 as it's the "Goldilocks screwdriver".
