I have an iMac (late 2009) with a broken graphics card. Fortunately, I have a new iMac (2019) which works fine.
I want to boot the old machine to Target Disk Mode to retrieve the data on the computer. I've read online you can connect them using a FireWire cable. Now the new mac doesn't have an FireWire connection but I think I can use a Thunderbolt to FireWire cable. So I thought I'll just order an FireWire cable, but there are a lot of different types. So my question is:
Which FireWire cable do I need to connect an iMac (late 2009) to a Thunderbolt to FireWire connection to retrieve the data using Target Disk Mode?
