Lion Server requirements

Mac OS X Lion Server has processor, memory, disk, and network requirements.

To install Lion Server on a Mac, the Mac must have:

  • An Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
  • At least 2 gigabytes (GB) of random access memory (RAM)
  • At least 10 gigabytes (GB) of disk space available

    Your server needs significantly more disk space—such as a high-capacity external hard drive—if you want to allow Lion, Snow Leopard, and Leopard users to back up their Macs on the server. A server needs even more disk space if you want to back up the server using Time Machine.

  • Mac OS X v10.6.6 or later; v10.6.8 recommended
  • An Internet connection, if you’re installing Lion Server from the Mac App Store

    An Internet connection isn’t required after installation.

Desktop or server hardware is recommended.

An active connection to a secure network is recommended for server setup, but isn’t required. After setup, your server must have a network connection for users to access its services.

Some features require a compatible Internet service provider.

Some features require an Apple ID.

Some podcast encoding operations require a compatible graphics card. Some features have additional system requirements or require additional purchases. For details, see the Lion Server website at

A Mac server can be set up and used without a display and can be located where you don’t have constant physical access to it. You can use another Mac to set up and administer a Mac server remotely. For information, see Prepare an administrator computer.
