How to connect new Macbook pro 2014 to iMac 2010 for a secondary display
I have a new Macbook Pro 2014 and an old iMac 2010. How can I connect them to have an additional secondary display? I thought I would need a thunderbolt cable with a Thunderbolt to Mini DisplayPort adapter but I can't find that. There's lots of options and I don't understand what would be best.
Macbook Pro 2014
iMac 2010
Any help would be much appreciated!
MacBook Pro (Retina, 15-inch, Mid 2014), OS X Yosemite (10.10.1)
