I want to connect to my old 2010 iMac to create a dual screen. There is no option for arrangements in the Display menu in System Preferences.
I can mirror the old iMac, but that is all. I need to extend my view as a dual screen.
Any help appreciated please?
thanks

iMac, OS X El Capitan (10.11.2)
Thanks I have seen this page. I am confused which cable I need though. I have aiMac 27" Mid 201 and want to link it with my iMac 27" late 2015.
Do I need a Thunderbolt to Mini DisplayPort cable?
Thanks
Barry
The Apple system requirements states explicitly, when using the iMac 27" mid 2010 as a target display a Mini DisplayPort to Mini DsplayPort cable connected to the iMac 27" Late 2015's Thunderbolt port (in your case).
iMacs you can use |
Cable |
Port you need on your other Mac |
iMac (27-inch Mid 2010) |
Mini DisplayPort to Mini DisplayPort |
Mini DisplayPort or Thunderbolt |
Apple does not sell such a cable. Comments on Apple Store site about using Thunderbolt cable confirm that Thunderbolt cable does not work.
This should work

Please, also note that
iMac (Retina 5K, 27-inch, Late 2014) and later iMac models can't be used as Target Display Mode displays
Did the Belkin cable work?
How do I dual screen with my new iMac?
