thunderbolt cable

The display on my late-2012 build 27” iMac has died — computer still turns on but that’s all. Apple no longer supports/provides replacement parts and I’m not interested in trying to find 3rd-party repair.


I have a MacBook Pro (2015 build) and a new 24” iMac (M1, 2021). I would like to use either of these as an external display so I can erase the fusion drive of the 27” iMac. I am having trouble determining which Thunderbolt-to-Thunderbolt cable to use. I think the 2012 iMac and the 2015 MacBook use the same Thunderbolt port shape; I know the 2021 iMac's Thunderbolt port is not compatible.


Any suggestions about cable type and sources much appreciated.


Tim

That won't work, because neither of those Mac's (the 2015 MacBook or the M1 iMac) support Target Display Mode.

Your best bet, is to try to access the 2012 iMac's drive in Target Disk Mode using a TB 2 cable from the MacBook.
