Reason: Because the Mac will check the software signature through Apple's server when it opens the software, there will be network communication during this process. If your network is not good, this process will be a bit slow, which will cause the software to keep jumping on the Dock bar and unable to open the application.

Solution:

Method 1: Shut down the network.

This method is very violent, because in the offline environment, the Mac will not check the network, you can directly open the software, open the software and then open the network.

Method 2: Modify the remote authentication signature of Hosts shield.

You can add host rules by modifying host files or related applications.
