can't save files to Pico W using Thonny 4.0.0 on MacOS

[Don Kossman]

Apologies if this is a known issue, if so please point me to any known solution!

Environment: 

- MacOS Big Sur on an Intel iMac

- Thonny Mac 4.0.0

- Raspberry Pi Pico W

- MicroPython v1.19.1

- connected via USB to my Mac

I installed MicroPython on the Pico with no issues using drag and drop to the USB volume. I am able to load and run python programs on the Pico with no problems using Thonny

However, i am unable to save any programs onto the Pico - the Save icon (floppy disk) is grayed out in Thonny.  I tried running Thonny as root,  same issue.

Is this a known issue on Macs with this version of Thonny?

I don't have a Windows machine to try this on - i tried running the Windows version of Thonny 4.0 using Crossover but it errors trying to connect to the Pico.

Any help would be appreciated!

thanks

I can't reproduce this problem on my Catalina but I don't have a Big Sur at hand.

Please report it on Thonny's issue tracker (https://github.com/thonny/thonny/issues). It could be useful if you posted a screenshot of Thonny window in this problem situation and also Thonny's frontend.log (Tools => Open Thonny data folder).

Best regards,

Update - I think this might just be a documentation issue or a result of me looking at obsolete instructions for older versions of Thonny.  I am able to use the File/Save Copy... dialog to save files to the Pico.  I was unaware of the File/Save Copy option, and based on what I'd read, expected to do this using the "Save" icon, i.e. i was expecting a popup that lets me choose to save to my computer or the pico,  But in both 3.3 and 4.0 o Mac clicking the Save icon only saves the current file to my computer.   Assuming that this is the expected behavior, there is no issue!

If a file is already saved (e.g. on a local disk) and is not changed, then it is expected that Thonny disables the Save command. This is actually quite common approach, so I didn't think it requires documentation. Only for unsaved / unnamed files Thonny is supposed to present the choice of target system and path. As you already discovered, Save Copy is suitable for saving the local file to "remote" target as well.
