Hi
I have an old iMac 27” late 2013
I searched for this and nothing seems to work. Some applications are not compatible because of the software version, it is not showing updates nor upgrades available.
App Store I can only see the latest so which is not compatible
other support posts showing different versions but nothing seems to work
pls help
A late 2013 iMac can be upgraded to Catalina 10.15.7 but no later. See: How to get old versions of macOS - Apple Support

Hello Again
herewith what I did:
1- Created a new partition.
2- downloaded Catalina installer patch from the developer website, opened, then downloaded it as ISO (the actual catalina to the mac on the new Partition) (no usb to create a bootable drive)
3- Ran the installation and sure the system was restarting until the configuration page reached (as if a new system).
4- Moved files after installation to the new partition with Catalina.
5- Erased the old partition
and here I am
Thank you, I have having problems with the info on that link, not working . Thank you for your response
Use Safari only for that link, though if you are on Mavericks, your version of Safari may be too old…
