Offensive security released the 4th and final update of its security operating system Kali Linux 2021.4 with newly updated hacking tools and support for Macs M1, theme enhancement, extended compatibility for the samba-client, and more.

Offensive security used to release Kali Linux OS version updates several time each and every year with new features, in order to provide the best experience for the cybersecurity community.


Kali Linux 2021.4 is the final version of this year since Kali Linux 2021.1 was released in February 2021, and Kali linux 2021.2 was released in June and Kali Linux 2021.3 was released in September.

  • Wide compatibility for Samba
  • Switching package manager mirrors
  • Kaboxer theming
  • Updates to Xfce, GNOME and KDE

Since Kali Linux 2021.1, users can install Kali Linux Parallels on Apple Silicon Macs, now the new version also supports the VMware Fusion Public Tech Preview.

 “We also have updated the open-vm-tools package, and Kali’s installer will automatically detect if you are installing under VMware and install the open-vm-tools-desktop package, which should allow you to change the resolution out of the box.” Kali Linux said.

Another important update is Samba Client extended capability and now at Kali Linux 2021.4 regardless of the version of the protocol the Samba client is now configured for Wide Compatibility so that it can connect to pretty much every Samba server out there.
