Thank you for the very rapid feedback ...
... I set up the VM with 'no mouse' but, during setup the trackpad worked. When the VM restarted after installation though, I can't use the trackpad so, I'm mouse-less and amn't familiar with how to tab through apps to launch them with keyboard only. I'm running Scientific Linux on a MacBook Pro.
Should I expect to be able to use the trackpad?
Thanks,
Deirdre.
