To use wireless as a WiFi hotspot in Apple's Mac system, it requires a computer to have other network access, which means it needs a network that can be used for the internet, such as a wired network. Especially for small partners who use MacBook Pro or MacBook Air, they sometimes need to share a wireless WiFi network with their mobile phones when they are out. So how do you set up the Mac WiFi hotspot? The

Or the hard-pressed Web Search job last time. If it was done, forget it. I ran the program to vtune and found several hot programs. It seems that there is always a little bit of sorrow in my mind. So we went on the road of optimization. In fact, this road is easy to complete. In particular, cainiao like me have used up all the optimization tricks and this road has come to an end. I'm not going to take advantage of my talent. Let's just focus on it.
