It should load the firmware utility fine (it did for me on 2015 MBP).Īfterwards, as mentioned in Arch Wiki the ISO signature needs deleting. Reboot holding ⌥ and pick the yellow boot option on USB key called "Windows". ~ $sudo dd bs=4m if=/Users/hali/Downloads/Samsung_SSD_970_EVO_2B2QEXE7.iso of=/dev/disk3ġ7825792 bytes transferred in 8.546376 secs (2085772 ~ ~ $ĭiskutil list now looks like this: /dev/disk3 (external, physical): This worked for me with the NVMe SSD-970 EVO Firmware ISO 2B2QEXE7 from here.
