Yes, of course, you can run that old iMac. As long as it starts up. Then you can access the data in a number of ways but that will depend on the exact model iMac that you have. If you tell us the exact model we can suggest ways to access (copy) the data using an external drive or perhaps via file sharing.


OTOH, OS X 10.11.6 is El Capitan, which was discontinued in 2016 (10 years ago) and the last update was in 2018 *8 years ago). Do not expect to be able to use it on the internet in any way. Online security technology has changed significantly since then and your old iMac will not work well (if at all) on the internet.
