Mac Not Recognizing Prophet 6 over USB

[anniehartforsure]

Hello!

I am running Mac High Sierra 10.13.6 and cannot get my Mac to acknowledge the existence of my Prophet 6 via USB MIDI.  It used to work just fine and I'm not sure what happened.  My computer happily works with a Nord Electro 6 and a Minimoog.  I wanted to update the software on my Prophet, but Sysex Librarian doesn't list that instrument as an option.  Before you ask, I have the MIDI port in globals set as USB and tried several cables :-)

Has anyone had this problem and if so, what can I do?

Thanks!

Reach out to Sequential tech support regarding the USB issue, and meanwhile try the update via DIN MIDI using any generic USB DIN interface is all I can think of at the moment.

Is your usb cable plugged directly into the Mac or are you using a usb hub? For some, hubs cause problems with connecting to outboard equipment.

I had a similar problem with a Korg Prologue last year. At first my Mac and it talked to each other and then ... not, for no apparent reason. My solution was to do the updates with a Windows laptop. At least, with the Prophet you have the option of updating via the midi port, as studiodc suggested. This is the way I do it.

I have this issue and after speaking to the excellent support guys, I have to send it off to be repaired - dead USB connector. Seems to be fairly common

"Fairly common"? I'd like to see some supporting evidence for that claim.
