Simplify 3d and Mac

[feste]

since i can't get effective support from manufacturers, i try in this forum. I use Mac. I have two printers: Alfawise U20 and Anycubic Chiron. Before I used the software on PC. With the mac when I change the print job, the volume of the printer remains fixed on Alfawise U20. In print jobs it is correct to select Chiron or Alfawise with different volumes. On PC instead selecting the different process also changes the volume automatically. Anyone have any suggestions?
