UPDATE IMAC LATE 2013 FROM CATALINA 10.15.7 TO SONOMA SOFTWARE.
[Re-Titled by Moderator]
iMac 21.5″, macOS 10.15
Your 2013's hardware is simply too old and as mentioned it cannot go beyond 10.15.7, if you want or need Sonoma it's time to upgrade to a newer Mac. Sorry but that is the simplicity of it.
Mac OS 10.15.7 is the highest possible for that model.
I want to update my iMac 2013 to Sonoma
