Very knowledgable about Apple Macs and iPhones and their operating systems. I bought a new MacBook Air through Mac Smart for my wife and Steve set it up for us transferring data, photos and email from her old Microsoft Windows computer. I am a longtime MacBook Pro owner and I thought I was more or less on top of all things MacOS, but I soon realised I had a lot to learn from him. Steve also sorted out issues we were having with our iPhones. We are very satisfied customers.
