I have a late 2013 Mac with High Sierra 10.13.6 installed. I cannot get any updates now and the system is running very slowly. Is this Mac able to support and install later OS? If so, which are compatible and how do I find them?
iMac 21.5″, macOS 10.13
Your mac can run up to macOS Catalina 10.15.7.

Do NOT attempt to upgrade the OS without a full backup in place.

I think we should find out why it's running slowly first off.

We need to see what all is running, a report from this will not display any personal info...
EtreCheck is a FREE simple little diagnostic tool to display the important details of your system configuration and allow you to copy that information to the Clipboard. It is meant to be used with Apple Support Communities to help people help you with your Mac. It will not display any personal info.
Pastebin is a good place to paste the whole report if you capture the URL while there…
Workable but harder for me to work with...the Note tool on the bottom of this editor's toolbar, as shown in the image, to copy and paste the output from EtreCheck. In a Reply before you click post, look for this to add longer texts...
It depends on what your exact model is.
If you are in doubt, go to the Apple menu and choose About this Mac.
Post a screenshot (not including the serial number) or tell us what it says about model and year (e.g. MacBook Air mid 2013 or whatever it says).
