Platformio serialports vs platformio device

I did not find much doc about platformio serialports. But per my usage, those two commands (platformio serialports and platformio device) are the same? It that right?

Yes, “device” was introduced with PIO Core 3.0 as replacement for “serialports”.

It seems that “device” hasn’t been replaced with “serialports” on the MacOS GUI version. Been looking for the files to replace so I can get it working again. Can anyone help?

You have multiple PIO Core in a system. Please remove obsolete instances and use built-in Core in PIO IDE

pip uninstall platformio
brew uninstall platformio

I don’t know how did you install PIO Core.

That did the trick. Thank You
I had installed it through the GUI application. Nothing in the terminal
