Is it possible to use a 2008 iMac as an extended display for a 2013 iMac?
I use my 2013 iMac to work from home. I have a fully functioning iMac from 2008 which I want to use as a second screen/extended display. I've looked up lots of instructions/tips online but am finding it hard to understand what I need to do to set it up - if it's even possible at all due to the age of the machines. Tech support wasn't really able to help due to the age of the older iMac.
I tried an ethernet cable connecting the two, but nothing happens despite me following instructions I found on several sites.
Would anyone be able to confirm if this is possible to do, given the age of the models, and, if so, what cables I need (in simple terms!)?
The 2013 iMac has:
- four USB 3 ports
- two Thunderbolt ports
- one Mini DisplayPort
- one ethernet port
The 2008 iMac has:
- three USB 2 ports
- two FireWire ports
- one Mini-DVI video out port
- one ethernet port
