I have managed to create an El Capitan VM. I did this by adding a new VM and starting it up with restoring from my restore disk. It downloaded my current configuration (one and a half hours) and installed that. Then, inside the VM, I downloaded El Capitan and upgraded. This all worked but took nearly a whole day to do!
I have a question. I have already downloaded El Capitan and have the ‘Instal OS X El Capitan’ app which I have placed in my backup drive without installing on my main machine. Could I have used this in creating my new VM and, if yes, how?
The second question is this. As I now have a VM with El Capitan I cannot seem to change the screen resolution. It is fixed at 1024x768 and this is the only option in the Display option in System Preferences. How can I get a display option equivalent to my main machine ( I have an iMac, non-retina)?
Thanks in advance.
Simon.
