Security 51 System Requirements

Windows minimum requirements

The Windows listing requires a 64-bit Windows 10 installation. Steam names an Intel Core i5-6400 or analogous processor and either an AMD Radeon RX 550 or NVIDIA GeForce GTX 960. These are minimum requirements, not a measured recommendation for every resolution or frame-rate target.

macOS minimum requirements

The macOS listing begins with Big Sur 11.7.10 or newer and specifies Apple M1. It also requires 8 GB RAM and 2 GB of available space. Steam does not currently provide a separate recommended macOS tier on the public page.

Before you install

Treat the 2 GB figure as available installation space, then leave additional free room for Steam updates, saves, shader caches, or operating-system needs. The official page does not publish a Steam Deck performance profile, a frame-rate target, or detailed settings guidance, so this page does not infer them from the minimum hardware.

Steam currently lists full controller support, but that feature label does not by itself describe every device layout or menu prompt. It also lists Steam Cloud and Family Sharing. Check the store again near purchase if any compatibility detail is critical, because launch patches can change requirements.

• Confirm a 64-bit Windows installation or the listed macOS baseline.
• Verify memory and graphics against the official minimum rather than the game's file size alone.
• Keep more than the bare storage value free for updates and system overhead.
• Use Steam's current feature panel for controller and cloud-support status.

Source and update policy

Every value above is transcribed from the official Security 51 Steam page and checked on August 10, 2026. Alawar is the developer and publisher. If Steam changes a component or publishes recommended specifications, the central registry and this table should be updated together rather than leaving conflicting values across separate guides.
