Arduino Uno & Mac no serial port

Hi People,

The serial port menu does not display the USB on both the Macbook air and the iMac, there's no communication possible with the Uno... I've read through many sites through Google, no luck at all, only frustration.

I have installed the FTDIUSB on the Macbook air, but that doesn't help, and I have read that these files are not needed on a Mac & Uno. But the iMac doesn't work too. On the Macbook air I've installed Windows 7 through Bootcamp, but no joy there...

Edit2: Anybody has a solution? DONE. After the board connected with Windows 7, it also talked back to my Macbook Air (after reset) and the iMac (no reset!)... Can't figure it out, but it works...

Thanks,

Snakes

Edit: I got it working on the Macbook Air under Windows 7. Had to install the drivers manually, after this, the USB was recognized and asked for drivers. After a restart, it was working. Now trying to get the Mac part working...

I have installed the FTDIUSB

This will not help (or hurt). The Uno does not have a FTDI chip on it.

I got it working on the Macbook Air under Windows 7

Is this by running Windows Natively or through a Virtual Machine (VMware/Parallels/etc)? Natively tells you the hardware connections are all fine. Through a VM tells you hardware and software are fine as well since the VM needs to talk to OSX to see the USB device in the first place.

When you attach the Uno, do you get the "Network Device Detected" Pop-up? If so, click "Configure" and then click "OK" (without touching anything else.)

Hi James,

Yes it was natively (bootcamp), not a Virtual machine. And no, there was no pop-up, which is really strange as I would expect this to happen. As I said, I just added hardware & drivers (via control panel) and it started working under Windows (it asked for drivers again after this). I have no explanation of why it suddenly works on the Mac platform, but it does.

Thanks for the reply,

Perhaps you had Parallels or Vmware running at the time you tried to use it from OS-X ?

Somehow (and I wish I knew how), the virtual machines are able to completely take control of newly attached USB devices, so that they are accessible to the guest OS and do not appear to programs running on the host OS.

If that happened, it would explain why OS-X could not see the device. Perhaps after you got it working with Windows, your second attempt with OS-X was different because you'd shut down the virtual machine?

Hi Paul,

Unfortunately that is not the case, I had no VM running as it is not installed on the Macbook air. Good tip though, but the mystery remains :wink:

Take care,
Snakes

This seems to be the number one google result for "macbook air and arduino serial", so I thought I'd post the thing that eventually fixed it for me:

I have no problems any more.
