Learn the basics of working.


1.Grant write permission to the current user

At this time, you need to add write permission to the current macOS user, follow the prompts to copy the command line to the terminal (bash, iTerm), hit the Enter key to run, and enter the password.

There are three authorization methods available. If the first one doesn't work, try another one.

Change YourName to your boot username.

sudo chmod +a 'user:YourName:allow write' /private/etc/hosts


sudo chmod +w /private/etc/hosts

Or(not safe):

sudo chmod ugo+r /private/etc/hosts

2. Grant write permission to Helm

Select the opened Hosts file, click Authorize, and the software can obtain the hosts write permission.

At this point, the two-step authorization operation has been completed. You can freely edit and combine the hosts file, and no further authorization is required from now on.
