Easy solution for Apple, just fix them for free.
I wish it was that easy!
I've had problems with dust and something like screen burn on my MacBook screen.
They replaced it for free. It happened again on my second screen. They replaced it for free. It happened again on my third screen. They replaced it for free. It happened again on my fourth screen. They gave me a new MacBook.
My friend has had the same issues, too. They had to replace her screen. It happened again on her second screen. They replaced it for free. It happened again on her third screen. They replaced it for free. It happened again on her fourth screen. They gave her a new laptop. It happened again on her new laptop. They gave her a free upgrade to a MacBook Air.
We're now at almost £7,000 worth of repairs and replacements between the two of us. Thank god they've all been on warranty.
Here's hoping it's over for me and this laptop lasts but... I think the 12" MacBook is just a poorly made product.
