#### System Requirements

##### For development

**OS**: Windows 7 SP1+, 8, 10, 64-bit versions only; macOS 10.12+. (Server versions of Windows & OS X are not tested.)

**CPU**: SSE2 instruction set support.

**GPU**: Graphics card with DX10 (shader model 4.0) capabilities.

The rest mostly depends on the complexity of your projects.

###### Additional platform development requirements:

Generally content developed with Unity can run pretty much everywhere. How well it runs is dependent on the complexity of your project. More detailed requirements:

*   Desktop:
    
    *   OS: Windows 7 SP1+, macOS 10.12+, Ubuntu 16.04+
    *   Graphics card with DX10 (shader model 4.0) capabilities.
    *   CPU: SSE2 instruction set support.
*   iOS player requires iOS 10.0 or higher.
    
*   Android: OS 4.4 or later; ARMv7 CPU with NEON support; OpenGL ES 2.0 or later.
