I plan to go to an Apple Store on Thursday and buy a Black MacBook. First of all, you can get the student discount in store too, right? If so, all I do is bring in a letter of acceptance to a college or some other form of identification, right? I have a high school lunch card with my picture on it, will that work? If not I'll just try to find an acceptance letter. Is it guaranteed that they will have a Black MacBook in stock? Or should I call ahead of time just to make sure? Second, I want to upgrade from 1 GB of RAM to 4. This will work perfectly, correct? https://eshop.macsales.com/item/Other World Computing/53IM2DDR4GBK/ Also, I read that you should wear an ESD wriststrap. Is that absolutely necessary? I can't seem to find one on that site that I would order the RAM from, and I don't really want to order a $5 wriststrap from another place. Thanks a lot!
