1. One day, the machine could not work well without warming up a lot and making noise. I tried loads of methods but couldn't work the problem out, so I sent it to the nearest Apple Store which was located in my city.

2. That shop was newly open and it was quite spacious and there were not many people in there. There was a man who took my mac, and checked it fully.

3. He politely asked several questions about when the machine had a black screen, and what I was doing the last time the computer was fine.

4. It was best to reinstall the operating system, which would take me ten minutes. After I agreed with his opinion, the seller immediately started to install the latest operating system for me.

I had a small Mac Mini which I had used for three years 我有一部使用了三年的苹果电脑
