Output box missing from the SEN2COR plugin (Mac)

I cannot set the output for the Sen2cor plugin in SNAP. The output box supposedly appears below the Source Product box, but it’s missing on mine (pic below). I’m running Sen2cor on Mac.

Is there a way to solve this?

It is not possible to manually select the output name in this case. It is Sen2Cor who sets the name and the output folder (the same than the L1C input product). It is made this way because the naming convention in the S2 products is important in SNAP. But if you need it, when Sen2Cor has finished the process and the output is opened you can save this product in the format and with the name you want.
