How to get macOS server for El Capitan
Hi,
I am using mac pro early 2009 with El Capitan 10.11.6 installed. I would like to install macOS server, but the version on App Store is not compatible as it requires macOS Sierra (not compatible anymore with this mac pro). Where can I buy the older version of the server?
thank you and best regards
