Because Catalina is the last version that is compatible.

See the following from Identify your iMac model - Apple Support

iMac (21.5-inch, Late 2013)

Model Identifier: iMac14,1

Part Number: ME086xx/A, ME087xx/A

Newest compatible operating system: macOS Catalina

How many people are likely to be 'bored' learning that their hardware will no longer be supported?


"In any case, knowing the details wouldn't change anything."


I think that depends on what the details were...


There is a clear winner here, and it isn't the consumer or the planet. Without being informed of the reasons it is impossible to know whether it is something to be regarded as inevitable and reasonable (such as the move to 64-bits), or something else (possibly quite trivial).


There are knock-on effects, too, such as third-party software suppliers deciding not to support 'obsolete' operating systems... It all becomes a money-go-round...

Thanks for your help and the suggestion. I will...
