I have more than one Mac Book Pro, and need to transfer large files between them.

Can I repurpose the USBC cable for power to transfer between Mac Books?

Is there a better/faster cable, or way to transfer files between MacBooks?


The charger included with the 2016 MacBook Pro is a standard USB Type C cable. It should achieve speeds of up to 10gbps. If you'd like speeds of up to 40gbps, I'd buy an official thunderbolt 3 cable from Apple. These should have the highest speeds.

NOTE: My bad, I looked into it and the cable is a standard USB C cable, not thunderbolt. Answer has been changed to reflect that.

  • I thought I read somewhere that not all USBC cables themselves are equal. – goodguys_activate Feb 10 '17 at 20:17
  • @LamonteCristo well how big is the file you're moving? There are some sizes where it really won't matter. – Jackson1442 Feb 10 '17 at 22:29
  • @LamonteCristo I noticed that the cable is actually USB c, not thunderbolt. The answer now reflects that. – Jackson1442 Feb 10 '17 at 22:32
  • Thanks. This is the article that confused me earlier blog.fosketts.net/2016/10/29/… – goodguys_activate Feb 10 '17 at 22:42
  • @LamonteCristo it confused me too :). From what it seems, USB c is capped at 5, not 10. SSUSB (blue ports) are capped at 5. For maximum throughput, you'll want any thunderbolt 3 port – Jackson1442 Feb 10 '17 at 22:46
