Hello everyone, when i hit upload for my simple servo-potentiometer project, it reads: · Transpiling… · Project was successfully transpiled. Searching for device… · Port with connected Arduino was found. Installing toolchains… but then it just stays like that and seems as though it isnt making any progress. Did i do something wrong? Should I keep waiting? Any help with this would be great. ---

Hi hi! When you hit the “Deploy \> Upload for Arduino” button a new window will appear. Make sure you have chosen the appropriate Serial port there. ---

Yep, you should keep waiting. The very first time you upload to a new board architecture (e.g., AVR) XOD downloads a compiler toolchain. It can be up to 200 MB, the size depends on your OS and the architecture. So on a slow Internet, it could take up to few minutes. We should really make a progress bar for it… ---

Thank you! But how can I tell which one is the right port (macOS) ---

I have A macOS and I’m using the Arduino mega 2560. I will try it again in a better location with faster internet. Thank you, I appreciate your support. ---

Alright so I tried it again, and it has been an hour now and it’s still in the same place. Is this normal for a macOS? Should I still keep on waiting? ---

It could be that you have a corrupted file downloaded (if you interrupted process on 1st download). I think the \*.tgz file gets downloaded to `/AppData/Roaming/xod-client-electron/packages/arduino` on Windows (maybe under tools sub-folder). If you can find the .tgz file, delete it (& probably restart XOD for good measure) and try again with decent internet connection. If you can’t find the tgz file, uninstall/reinstall of XOD should clear it. The good news is XOD only needs to do this download the 1st time it tries to download to Arduino after installing XOD ---

Ok, thank you! I will uninstall, then reinstall XOD because I think that I may have interrupted the process on the first download (I left for a break and when I came back there was a connection error and the XOD downloading stopped and I had to hit resume). I really Appreciate this information. Thank you!! ---

hi I’m brand new to all this, and the same thing with “installing toolchains” is happening to me. what did you have to do to make it work? ---
