1. Open a terminal and figure out the hostname of your Mac. To get the hostname, use the command hostname.

   Code Block
   language text
   hostname joesLittleMacBookPro.local

   The command returns the hostname of your Mac. In the given example, the hostname is joesLittleMacBookPro.local.
   
   

2. Open the file /etc/hosts with an editor of your choice. You will edit the file in the next step.
   The file belongs to the system user root. Your user must belong to the group admin; otherwise, you cannot save the changes to the file. You will be asked for your password either when opening the file or when trying to save it.
   
   

3. Add these two lines to /etc/hosts:

   Code Block
   language text title /etc/hosts
   127.0.0.1 <hostname> ::1 <hostname>

   In place of <hostname>, use your real hostname.
   Most probably, your hosts file already contains entries starting with 127.0.0.1 and with ::1. Just add the real host name hostname at the end of one line that starts with ::1 and at the end of another line that starts with 127.0.0.1. Make sure to add a space character before the hostname.
   With the given hostname, the two lines would look like this:

   Code Block
   language text title /etc/hosts
   127.0.0.1 localhost joesLittleMacBookPro.local ::1 localhost joesLittleMacBookPro.local

4. Save the file. The system may ask you for your password.

JAR file does not start

When installing the Enterprise Edition DX Core on Windows, you can start the installer by double-clicking the JAR file. If this does not work there is a chance that some application on your system has registered the .jar extension.

You can try to fix it yourself by restoring the association of the .jar extension with the javaw.exe executable. .Right-click the JAR file and select Open With. Typically the javaw.exe file is in C:\Program Files (x86)\java\jre6\bin). Alternatively, start the installer from a command prompt with the following command: java -jar magnolia-dx-enterprisecore-installer-x.y.z.jar. Make sure the file extension is .jar. Internet Explorer has a tendency to append or change it to .zip.
