What if the app Store in Apple Mac doesn't open?

1. On the desktop of the Apple Computer, click on "Network" as shown in the following image.

2. Then in the Open Network window, we click "Open Network Preferences" to enter.

3. Then we open the interface and click "Advanced" as shown in the following figure.

4. This is the place to set up the network's DNS server.

5. In the DNS Settings window, click the + button on the lower left, enter a new DNS address 114.114.114.114, as shown in the figure

6. If you have multiple DNS addresses, make sure 114.114.114.114 this address is on top. Then click the "OK" button to return, as shown in the picture

7. Set us up and click "Apply"

8. Then we turn off the previously opened App store in the background (the ipad closes the background program tutorial).

Summary, in looking at a lot about the App Store can not open the solution to the problem, in general, all set up DNS will be able to solve, if this method does not solve our change for a period of time to try again.
