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 listed for Windows and macOS, with Full Controller Support. The Windows minimum uses an Intel Core i5-6400-class CPU and Radeon RX 550 or GeForce GTX 960. The Mac minimum is macOS Big Sur 11.7.10 or newer on Apple M1. Both list 8 GB RAM and 2 GB 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.
Official Mac minimum requirements
| Part | Steam requirement |
|---|---|
| Operating system | macOS Big Sur 11.7.10 or newer |
| Processor | Apple M1 |
| Memory | 8 GB RAM |
| Storage | 2 GB available |
Steam does not provide a separate Intel Mac minimum or a promised frame rate. Do not translate the Windows GPU row into a Mac performance guarantee; use the Mac table for buying compatibility.
Check your hardware before buying
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.
