there's a red X next to your board, it might not be visible to your system.
try disconnecting/reconnecting it.
does it work with the regular IDE?

I see on the old IDE u can switch the programmer

I doesn’t finde it on the new IDE ?

[ubidefeo]

there are functionalities and features which are being implemented and others which can break every now and then. the perks of Alpha versions :D

tomorrow I'll run a test with a Nano as soon as I get to my lab.
which version of Mac OS are you on? I'm on Mojave.
I doubt it's an OS thing but good to have as much information as possible

I've explained the cause of the red X issue here:
#198 (comment)

I suspect the cause of the failed upload is #10. @StipeElektrotechnik, in the Arduino IDE, what do you have selected in the Tools > Processor menu when you are using your Nano?

arduino/arduino-cli#27 is at the heart of this. But that has nothing to do with the upload error you are getting. The Arduino IDE's Tools > Programmer menu selection only matters when you are doing an Upload Using Programmer or a Burn Bootloader. It makes no difference when you are doing a normal upload.
