    I installed the latest firmware on a Ramps 1.4 board and I checked it’s Ok.
    It shows the ‘HELLO WORLD’ text on the serial monitor.
    I tried to connect to the Ramps board with the latest Makelango software on Mac OSX v10.12.23 but it sees no usb ports, so I cannot connect to the Ramps board.

    See picture.
    Empty list of usb ports

    How can I fix this?

    I uploaded a link to a picture but apparenty this forum ignores picture links.
    Anyway, it is not difficult to imagine an empty select box.
    But who cares, I paid for the software and my request for support is also ignored.

    I thought this was an actively maintained forum.

    It is actively maintained. I answer as fast as you post.

    Please suggest how I should diagnose/fix something that seems to happen only on your computer.

    Have you tried to reproduce the issue on Mac OS X Sierra?
    I was waiting on your feedback on that.

    I only have Yosemite (10.10.5) on a Macbook Pro.

    I thought you had a couple of thousand customers all over the world.
    I guess you know a few who use Macs with the latest OS version.

    But if you are unwilling to help a paying customer then I guess you would indeed do nothing.

    Dan hi, im also getting the same issue on Sierra. It does not display any com ports, the drop down is empty. I double checked using windows and other software and the port is OK.

    Ok, now that’s weird. I need to find a copy of newer OSX to test this for myself.

    I wonder if this is related: Sierra doesn’t seem to support some USB drivers very well:

    https://forums.developer.apple.com/thread/61472

    “The use of a Fresh Roast SR700 Coffee Roaster also crashes Sierra because of this CH340 chip usb/serial driver incompatibilty too.”

    CH340 is used in several arduino clones. RUMBA is merely arduino-compatible, it may be victim to a similar issue.

    Ok, I’ve asked the original equipment manufacturers. I’m getting to the bottom of this. Thank you for your patience and understanding.

    Ah, second customer complains and Dan finally gets into action!

    Two people means it can’t be just user error.
    I doubted you and that was my mistake.
    I’m sorry I didn’t help you faster.

    Dan i think its not an issue with Sierra. I flashed a rumba and it does show the correct port. So either we are flashing the ramps incorrectly or we are modifying the firmware wrong , at least in my case.

    Would you mind making the changes yourself to the firmware to be used with ramp to confirm?

    In a perfect world you’d make a pull request from github with the changes. that way
    – your name would show up in the credits if future employers look for your name; and
    – you know the code works right because you tested it before making the pull request.

    …but I can do it if you give me the details, and we’ll cross our fingers that it works.

    As far as I know there’s no way to load bad Arduino code onto a board such that the USB does not load. I mean, the USB has to load so you can send the code to the Arduino!

    Are you flashing the bootloader? That should not be necessary at all.

    I was referring to the changes needed on the config.h so that ramps is the chosen board.
    By default rumba is the board isn’t it?

    Then to use ramps you uncomment the following in config.h

    // Your choice of board
    //#define MOTHERBOARD BOARD_RUMBA
    //#define MOTHERBOARD BOARD_RAMPS . <———
    //#define MOTHERBOARD BOARD_SANGUINOLULU

    Or whats the procedure?

    I agree with you that it does not make sense but rumba connected immediately and ramps just does not show the port

    I understand a bit better now. uncomment

    #define MOTHERBOARD BOARD_RAMPS

    and make sure other MOTHERBOARD lines are commented (lines must start with //)

    Note that RAMPS is not officially supported and I have not tested it, ever. Please report back with your success.

    FWIW, I’m connecting random RUMBA boards from my inventory.

    In Windows 10 every unit is showing a COM* port and I’m able to upload firmware.

    In OSX every unit is showing a /dev/tty.usbmodem* port and I’m able to upload firmware.

    Can you tell me your order #? I want to find out when your order was assembled and by whom to narrow down what could be causing the issue, if it’s on our end at all. I suspect it’s a problem with OSX Sierra. Evidence here:
