Using Server Admin
1. Open Server Admin and log on to the Server.
2. Click the General tab.
3. Choose Show Server Info from the Server Info module.
The Server Admin can be found in /Applications/Utilities/ folder. The Mac OS X Server CD-ROM also includes the "Admin-Install.mpkg" file that you can use to install Server Admin application on a Mac OS X 10.1 client computer. It can be found on the CD in this location:
/Mac OS X Server/Welcome to Mac OS X Server/Admin Install/Admin_Install.mpkg
Using the Terminal
Experienced administrators may determine the version of Mac OS X Server by using the uname command with an "a" flag (uname -a) via a remote Terminal session.
This command works with Mac OS X Server, but will only output system information that relates to the UNIX-based foundation of Mac OS X Server, known as Darwin. For example, it can provide the following output:
[macosxserver:~] admin% uname -a Darwin macosxserver.domainname.com 5.2 Darwin Kernel Version 5.2: Fri Dec 7 21:39:35 PST 2001; root:xnu/xnu-201.14.obj~1/RELEASE_PPC Power Macintosh powerpc
To determine the version of Mac OS X Server via a remote terminal session, use the sw_vers command. For example, sw_vers can provide the following output:
[macosxserver:~] admin% sw_vers ProductName: Mac OS X Server ProductVersion: 10.1.2 Server BuildVersion: 5P68
