Security 51 System Requirements — PC, Mac, and Controller Support
A current Security 51 compatibility checklist built from the official Steam listing, including the distinction between supported Mac storefront access and its published PC hardware requirements.

Short answer: Security 51 is currently listed on Steam for Windows and macOS, with Full Controller Support. Its published PC minimum is Windows 10 64-bit, 8 GB RAM, an Intel Core i5-6400 or equivalent processor, a Radeon RX 550 or GeForce GTX 960, and 2 GB of available storage.
Official PC minimum requirements
| Part | Steam requirement | | --- | --- | | Operating system | Windows 10 64-bit | | Processor | Intel Core i5-6400 or equivalent | | Memory | 8 GB RAM | | Graphics | AMD Radeon RX 550 or NVIDIA GeForce GTX 960 | | Storage | 2 GB available | | Controller | Full Controller Support |
Steam does not currently publish a separate recommended PC tier for Security 51. Treat the table as the developer's minimum buying information, not a promised frame-rate setting. The game is listed as single-player and includes Steam Cloud, achievements, trading cards, and Family Sharing in the current storefront data.
Windows and Mac: what the listing confirms
The platform badges confirm that the developer lists Windows and macOS support. The detailed hardware text above is specifically the published PC requirement. A Mac user should therefore confirm the live macOS compatibility details on the Steam purchase page and keep the store's current refund policy in mind; translating a GTX 960 requirement into an Apple Silicon performance promise would be speculation.
For Windows, open Settings → System → About to check memory and CPU, then use Task Manager → Performance → GPU or dxdiag for the graphics adapter. Compare the actual GPU model to the table. On a laptop, use the dedicated GPU rather than only the integrated graphics name.
Full Controller Support is a clear storefront declaration, but it does not tell us a preferred controller layout or sensitivity. Test the current build's button prompts and remapping options yourself rather than relying on an old demo report.
