I was planning to use this product for html, and for business purposes, well when I first got the mac, it took a really long time for it to update. Furthermore, it wouldn’t turned on unless, it had the adapter plugged in, which a replacement battery ain’t that much, but the description saids that it will be at least 80 percent or above. The seller PLATINUM DEALS, was really helpful, but I’m returning this Item and getting a Lenovo, save yourself the time and money.
