OS X Server 5 Is Alive!
If you’ve been running Yosemite Server (OS X Server version 4), you may have received an App Store notice about a free upgrade to OS X Server 5. According to Apple, OS X Server 5 is “operating system independent,” meaning that it can run on both 10.10.5 Yosemite (and later) and 10.11 El Capitan. Charles, nonetheless, says that while OS X Server 5 does run on Yosemite, he doesn’t really recommend doing so. He also notes that OS X Server 4 won’t run on El Capitan.
So, bottom line, if you plan to upgrade your server Mac to El Capitan, get the OS X Server upgrade at that time—not before. Also, we recommend that you wait until people like Charles test Server 5 and report back.
