Numbers can't download

Hi c,

iOS is found in iPhones and iPads (in a variant called iPadOS),

Your 2012 iMac, according to your equipment profile (top left of your post) is running MacOS 10.15.

This post, by The_Knowledge_Seeker comes from a discussion of a similar question:

Only these Macs will run macOS 11.0:

• MacBook (2015 or newer)
• MacBook Air (2013 or newer)
• MacBook Pro (Late 2013 or newer)
• Mac mini (2014 or newer)
• iMac (2014 or newer)
• iMac Pro (from 2017)
• Mac Pro (2013 or newer)

Sadly this doesn't Include your mid 2012 Mac :-(

Catalina (MacOS 10.15) appears to be the most recent that will run on your Mac.

Regards,

Barry
