In order to install the Lavu Local Server (LLS), the account must first be authorized by the Lavu Billing Department. To have your account approved for an LLS installation, email Once the Lavu Billing Department has approved the account for an LLS they will coordinate the scheduling of the installation time by Lavu Support. Appointments for LLS installations must be made 24 hours or more in advance.

It is very important that the Mac mini that the LLS software is installed on is not used for anything other than the LLS. Any additional operations performed on the Mac mini running the LLS software can jeopardize the efficiency and reliability of the LLS software.

The Mac mini purchased to run the LLS software should not be a Server Edition Mac mini. The minimum hardware requirements to run LLS is available on the basic model of the Mac mini, however, upgrading the RAM and processor will be necessary for higher volume locations. 

Lavu recommends that the Mac mini be plugged into a secondary power source (battery back-up or UPS) in case of a sudden loss of power at the location. Sudden, improper shut downs of the Mac mini can break several elements of the LLS software and/or the operating system (OS). To prevent these breakages, a back-up power source will allow the user enough time to shutdown the Mac Mini properly until a reliable power source is restored.

The USB cable for the battery backup should be connected to the Mac Mini and the computer should be set to shut down when the battery is low. (System Preferences > Energy Saver).

In order to expedite the installation of the LLS software, please have the following settings configured:

1. Have a mouse, monitor, and keyboard connected to the Mac mini.

2. Set the Mac mini to never sleep (System Preferences > Energy Saver).

3. Allow the Mac mini to download and install apps from “Anywhere” (System Preferences > Security & Privacy).

4. The Mac mini should be hardwired (via ethernet cable) to the router (the same router providing the wireless network for the iPads running POS Lavu).

5. Disable the Wi-Fi on the Mac mini (System preferences > Network).

6. Enable Ethernet on the Mac mini (System Preferences > Network).

7. Set the Mac mini to a Static IP Address outside of the DHCP range of the router. Be sure to not set the Mac mini to the same IP Address as a printer or other statically set device.

Most set-ups will appear similar to Figure 1 and 2.



In order to configure the DNS Servers, click “Advanced” from the Network > Ethernet settings. Click DNS from the options along the top of the new window then click “+” for DNS Servers. Enter the IP Address of your router. Repeat this operation and enter “”. Click “Ok” to apply the changes.

8. It is also important that the Mac mini is on Mac OS High Sierra (unless otherwise stated by Lavu Support). If the Mac mini is not on Mac OS High Sierra, it will need to be installed prior to the installation of the LLS software. Once the LLS software is installed the OS should not be updated unless cleared by Lavu Support.
