Hi, I have a white macbook 13" from 2007. It's old, I know. I bought it refurbished from Apple and since then I've replaced a crashed hard drive/upgraded memory/battery but otherwise it's running well. Now I'm looking to replace the keyboard because the buttons are sticking and difficult to type on. I'm not good enough with computers where I feel like I can do this myself but thankfully I have a fiance who could probably pull it off. I haven't seen much online about keyboard replacement but I feel like it must be possible to do. I'm wary of buying products that are not made by Apple because I've been ripped off in the past on a discount battery website, but I will do so if someone knows of something that has proven to be reliable. Is it possible to replace the keyboard, and if so, what's the best and most cost-effective way to do so?
