This software updates OS X Server v5.0.3, v5.0.4, or v5.0.15. It requires OS X El Capitan v10.11.4 to install.

OS X Server v5.1 is the only version of Server that runs on OS X v10.11.4. If you upgrade a Mac running a previous version of OS X and OS X Server to OS X v10.11.4, you must upgrade to OS X Server v5.1 as well. If your Mac uses a version of OS X prior to v10.11.4, you must upgrade to OS X v10.11.4 in order to use OS X Server v5.1.

How to update

On Macs running OS X v10.11.4, update to OS X Server v5.1 from the Updates pane of the Mac App Store. To prevent the interruption of services, Server updates aren't automatically installed, even if you've chosen to install other updates automatically from the Mac App Store.

During installation you may see the message "Server app replacement detected." This is a normal part of the update process. All Server settings and data are preserved during the update.

After installation is complete, open Server app to finish setting up your previously configured services.
