Install El Capitan (macOS 10.11) VM - fix OSX could not be installed on you computer. No packages were eligible for install.

Error message when attempting install:

OSX could not be installed on you computer. No packages were eligible for install.

The problem - the certificates in the installer are out of date. In order to address this, we can change the date and time on the command line, but we will need to disable networking first.

In your virtualisation manager, disable the network interface connected to your VM.

Under "Utilities" in the top menu bar, choose "Command Line".

Once it has loaded, enter the following to set the date back to a magical time when this cert worked:

date -u 0531173216 (May 31st, 2016)

Then close the Command Line app (cmd+Q, or from the menu).

Click "restart" in the installer window, which will reboot (time is kept as NIC is off) and your install should complete!
