iMac 2013 in Target Display mode for iMac
I have a 27" iMac late 2013 that I would like to use in Target Display mode to act as an external display for a 21.5" iMac 2017.
The late 2013 iMac uses Thunderbolt 1 and the 2017 iMac has Thunderbolt 3.
Will the simple all-in-one USB C to Mini DisplayPort Cable
cable available for around 15 bucks on Amazon work SOLELY for that purpose?
Or do I need to use Apple's Thunderbolt 3 to 2 adaptor along with a Thunderbolt 1/2 cable to make that work?
I tried to include a product link but it won't let me.
Thank you for anyone who knows.
