linking Macbooks with different OS
I have an old 2013 Macbook Pro running OS High Sierra (for Quickbook Pro limitations) and am buying a new Macbook Pro running OS Big Sur. I would like to link the two MBs so that I can run Quickbooks on the old Macbook via the new Macbook running OS BigSur. First, is this possible? Second if it is do I need the lightning cable? Finally, if it is possible, can I keep the old Macbook on with the lid closed while doing this?
