Power Adapter for 2007 black MacBook
My dog chewed my power cord for my 2007 black MacBook, and I need to buy a new power adapter. I went to Best Buy (since it's much more convenient than the Apple Store to my house), and after the sales guy talked to three or four different tech people, they told me that the power adapters they had in stock would only work with the new MacBooks, and definitely not with the old ones. Is that true? What adapter do I need for the old black MacBook? I'm not sure that the people at Best Buy know what they're talking about. Thank you!
