Hello,
The set up
I'm using MacOS Catalina 10.15.4. The Arduino Nano board I'm using is using the CH340G USB-to-serial chip for which I have tried to install the v1.5 drivers (most recent) version. I say tried because, while it says success at the end, I've looked at the procedure to remove them and none of the files that need to be deleted are there... Ok, so I think that's all for the set up.
Note : The board is working, it's doing the last sketch I had uploaded to it months ago.
P.S. : I forgot to mention that Genuino boards are not having this problem at all, the upload works flawlessly with them.
The problem
I'm trying to flash the blink sketch (which compiles successfully) to the board, it fails with the console output just lower. I have tried the lsop verification, there's no output, which means no program is using the port. I have also tried to delete the things that appear in the Network tab of the system preferences. A weird thing that happens when I plug the board though is that 2 ports seems to appear in the list :
/dev/cu.usbserial-1410
/dev/cu.wchusbserial1410
The error happens on the first one. The second one says the programmer is not responding 10 times, then stops.
Any help would be appreciated, I don't know where to look anymore...
