This file is integrated within the Fusion software to install drivers for Mac OS X systems. You need the Darwin.iso file to manually install or update the drivers for your macOS guest system. If you want to update the drivers of your virtual machine without updating the virtualization software you are using, it is recommended to install VMware tools manually. That’s why you can see the “Update VMware Tools” option instead of the “Install VMware Tools” option in the tool menu. When you update the virtualization program installed on your host computer, the integrated VMware Tools ISO file is also updated automatically. However, it is recommended to install the drivers for your guest system using the darwin.iso file downloaded with VMware Unlocker, which you used when installing a macOS version with VMware Workstation.


When your settings match those in the image below, click on “Next”.In order to install drivers in the macOS guest operating system running on VMware virtualization software, you can install with the existing ISO file in the software by clicking “Install VMware Tools” from the tool menu of the software.

Note that you need to have Virtualization enabled in your BIOS otherwise you will not see this option. Next, give your OS a name and change the “Type” to Linux then select “Debian (64-bit)” from the “Version” menu. Begin by opening VirtualBox and then clicking on “New” to create a new VM. Note that you need to follow this section exactly, otherwise your installation will fail. Now that you have downloaded all the necessary files, you are ready to begin setting up the virtual machine. Note that this file will be updated whenever a new major build is released. The last item you need to download before you can install SteamOS is obviously the Steam OS ISO. Since this tutorial is using VirtualBox 5.0, you can download this version of the VBox Guest Additions ISO. It is normally the sixth item down from the top on the index page. Once you get to the download page, click on the option that corresponds with your version of Virtual Box then download the “VBoxGuestAdditions_X.X.X.iso” file. The second download is VirtualBox Additions which can be notoriously difficult to find which is why I recommend clicking on this link rather than trying to find it yourself.
