Use 2011 iMac as an external display AND external disk for a 2017 iMac?
I'd really like to use my 2011 iMac as an external display AND external disk for a 2017 iMac.
Plenty of articles on how to do each separately but not at the same time. (I have done both).
Currently both use High Sierra (10.13.6)
iMac Line (2012 and Later)
