Update the S1 Pro firmware: My mac doesn't see the product
I am trying to update my S1 Pro from my Mac (macOS High Sierra)
On the btu.bose.com website, form the S1 pro page i have the message: "Turn the device power switch on and leave it on until the update is finished."
Here is what i did
1) I fully charged my S1 pro, i turned it on, and i have it pugged into the AC.
2) I plugged it to my mac with a micro USB cable.
3) I downloaded/installed to Bose app (from btu.bose.com), and run it (i can see it from my toolbar and the btu.bose.com recognizes it since it doesn't ask me to install it).
4) I unpaired my S1 pro from my phone (i know it's not a required step but i have seen that solves the same issue with peoples who try to update their Quietcomfort 35 ii)
So now i really don't have idea what i miss or could try, any idea ?
Of course i tried to restart my mac, restart the S1 pro, always the same error message...
Thanks for your help !
