Yes, dialabrain is technically correct, you do need Thunderbolt 3 to fully use an eGPU, due to Thunderbolt 3's speed and data transfer ability vs Thunderbolt 2......thunderbolt 2 might possibly work, but can't say for certain that it will work 100%, never having owned or used an eGPU..... Check out this post on the egpu.io forum for more infomation....https://egpu.io/forums/mac-setup/thunderbolt-2-fast-enough-to-handle-gpu/....
