DDO was ported and validated using newer Mac hardware and as such the requirements presented tend to err on the higher end. There are currently no accurate 'minimum' system requirements.

The OS X Client for DDO uses OpenGL for rendering. At the Ultra High setting OpenGL renders all DirectX 9 content. There are a few features present in the DirectX 10 and 11 that are not supported at this time including:
 * Shadow Maps
 * Soft Shorelines
 * Soft particles
 * Volumetric sunlight
 * Ambient Occlusion
 * Interactive Water

Beta Wine client for MacOS (May 2019):

Support for other computers and operating systems
For older Macs with Intel processors, DDO may still be able to be run either using Boot Camp to host a Windows installation or by using a virtualization application such as Parallels, VMware Fusion, or WINE. Intel Integrated Graphics may prove ineffectual for rendering the game, a dedicated graphics card is highly recommended. PowerPC Macs are not supported.

Linux users may opt to try Wine, an API translation layer that allows many Windows applications to operate in the UNIX-like operating system. See DDO On Linux for more help getting it installed on a Linux operating system using Wine. A fully virtualized PC using a tool such as VirtualBox with the Guest Additions installed (and 3D graphics enabled) or VMware Workstation Player can also be used to install a full Windows OS environment.

2019 update:
 * MacOS: New Client Available and FAQ
 * Do not upgrade to Catalina for MacOS

2020 update:

64-bit client
Since Update 45 (Feb 2020), the DDO game client can run in 64-bit, which can improve game performance. By default, you continue using the 32-bit client unless you manually change the option in the launcher (Options > General tab > Game Client). You can toggle between 32- and 64-bit versions at any time.
