Cant see Pico in Mac OSX

That's fantastic news - and the speed at which you address stuff is amazing - cheers!

Thanks! No problem...

To be fair the original post was 3 months ago - hopefully @tony1tf hasn't given up with it yet!

Just an update. dfu-util did not work for me.

This was the output:

dfu-util: Invalid DFU suffix signature
dfu-util: A valid DFU suffix will be required in a future dfu-util release!!!
dfu-util: No DFU capable USB device available

I found another computer and got 1.80 on it via the IDE and I can now see the Pico on the 10.6.8 machine with:-
ls /dev/tty.*

Did you also follow the advanced flash instructions from that page I linked? You have to pencil over some pads on the back of the board then hold down the button while plugging it in.

It's great that 1v80 works, but you'll find that as-is you may have to always plug into another computer in order to update the firmware.

I did, I followed all the instructions there. I pencil shorted the button connection, and assume it was was good enough but perhaps it wasn't. Anyway not a problem. I'm up and running with the Pico. Next time I want to update I'll try dfu-util again and try the other approach via the battery.

Hello,

I've just received my Pico. As above, the tty drivers do not show up on my OSX 10.11.1 machine. However on a OSX 10.10.x machine it works.

So I tried the flashing instructions and upgraded to V1.81 on the OSX 10.10 machine. Seems to work fine. When I connect on this machine, it show the correct (new) v1.81 version firmware.

However, when coming back to the 10.11 machine I still get the errors:

(also too bad I got a v1.3 board, when apparently the v1.4 is the latest version)

Hi - there's not much difference in the board revisions - the 1v4 is made in China and has a fuse on-board, but otherwise they're basically the same.

So you're having trouble with a newer MacOS? The problems people were having previously were with 10.6.8.

This is the first I've heard of that being an issue though - I ran a workshop a week ago where virtually everyone had brand new Macs, and it worked fine on all of them.
