Target Display Mode not working. Is thunderbolt the problem?
I'm trying to use an old iMac 27-inch (Mid 2010) as a monitor, using the Target Display Mode without success. I'm connecting a MacBook Pro (Retina, 15-inch, Mid 2015).
The cable is a completely new Thunderbolt - Thunderbolt cable. I've tried resetting SMC and NVRAM on the iMac which haven't solved the problem. I've also tried the VirtualKVM application but it looks as if the Thunderbolt port isn't recognising the cable.
Obviously the CMD+F2 option isn't working either.
Es esta una buena pregunta?
