In Part 1 of this post, we downloaded the most recent Kali Linux ISO and verified its checksum. In Part 2, we installed Kali Linux in our virtual machine and logged ourselves in. We’ll now update and upgrade our Kali Linux installation and install Parallel Tools.
Step 1: Updating and Upgrading Kali Linux
Start up Parallels Desktop and select the Kali virtual machine.

Once Kali Linux starts, log in using the “root” credentials set in Part 2. We’ll use the Linux Terminal to perform the next two steps. Start the Terminal by clicking its icon in the upper left as shown here:

Once the Terminal starts, type the following at the command line:
apt-get update
and press Enter.

Kali will process all of the published updates since the ISO distribution used for the installation.
