I've got a macbook and the cord coming out of ts adapter fried itself, so i need a new one. I looked on the apple store and they have an 85w adapter for the 15 and 17 inch models and a 45w adapter for the macbook air but they are missing the required 60w adapter for the 13 inch.
Would it work if I got the 85w adapter or would that be too much power for my macbook to handle?

There is nothing wrong with using a higher wattage for a device.
The thing to really make sure is that the power supply output has the same DC voltage as required by your laptop. Double check what DC voltage your computer requires and double check the DC voltage output on the power supply you are looking to buy.
The DC voltage is something in the range of 6VDC, 9VDC, 15VDC, something like that. The power supply will also say 110-240V but that is for the AC voltage coming from the wall.
Different DC voltages also use different size plugs, so you want to make sure the DC output plug on the power supply fits your computer too.
If the DC voltage is OK, there is no problem using a higher wattage.

Like the above poster said, higher wattage = no problem, and make sure the DC output is the same, but you also have to make sure it's pumping out the same amount of current. (measured in Amperes, denoted "A", the values are around 0.3A to 3.0A) Too much, or too little current can wreak havoc with electronics.
