How do I use the e-tube software on my Apple Macbook?

Unfortunately you can’t! Shimano has not made the e-Tube project software available for Apple (Macbook) devices. This can be a real problem to those wanting to update their Di2 firmware. If this is you, we suggest the following workarounds:

  • Take your bike and your SM-BCR2 charger to a friend and hook it up to their Windows laptop/pc
  • Take your bike to a good Local Bike Shop (LBS) and ask them to update your Di2 firmware. They will be glad to help at low or even no cost
  • Install the e-Tube project mobile app (if you have the Wireless Unit) and update firmware that way. Be aware you may need to reset the system.
