it ships with Operating System macOS Big Sur 11.0.

I don't know where that ranks. I can tell you what Tiger and Panther and Leopard run on, but not Big Sur 11.0.

The same model, but with an M2 chipset,

ships with Operating System macOS Monterey 12. I don't know how far up I can go with the M1 chipset.

I absolutely do not need the latest bells and whistles. The version with the M2 is an extra $550. Yikes.

Apple says
