I'm concerned that requiring macOS 12 will exclude a sizeable chunk of my customers.

Some data from another vendor in our industry (audio plugins):

macOS 10.x = 31%
macOS 11   = 8%
macOS 12   = 23%
macOS 13   = 25%
macOS 14   = 10%

Assuming this data also represents my customers, I'd potentially be excluding 39% of them by forcing this requirement. A lot of music producers will stay on older macOS versions for various reasons.

Can you please explain why this requirement is necessary, and if there is a way to reduce it, ideally back to Catalina or Mojave?

Thank you
