[Solved] Flashing new Spark core not showing in DFU

All, I only have an apple Mac or my pI, I’ve tried the other threads on flashing, bit of diagnostics, the core looks like its in DFU as the light is flashing what looks like yellow, (not white blue or any other colour).

Any ideas.


Just an update, seems the Spark crew send out faulty usb cables, tried 3 different ones and finally got the Raspberry pi to see it.

Problem solved.
