This will probably not work with an 860 EVO, as the Macbooks from 2015 onwards do not support the AHCI SSD protocol. Your Macbook Pro should support the NVME protocol - that would be a Samsung 960 EVO (or 970 EVO - I'll try that in the next few days). Anyway, you need an SSD adapter to PCIe (M2 adapter card to Mac SSD 12+16 pin).
