Antwoord op "iMac restarts. kernal panic report. NVMe SSD stops being recognized."Hello John and Dan I’ve unwittingly stumbled into this issue too, after upgrading the drives in my Late 2015 iMac. I put in a WD Black drive and it is recognised and works fine, until waking up from sleep when the kernel panic occurs. Can you recommend a 500GB blade that would work with the slower motherboard? Or if I put the WD drive in an external enclosure would that get round the issue, or would the motherboard have the same throttling issue too? A real pain to have to strip the screen off again….
