Valorant on Mac M4 Fact-Check: Why No Workaround Beats Vanguard in 2026
To understand why compatibility fails, you must understand operating system rings. Most applications operate in Ring 3, the user mode. Web browsers, office suites, and standard game executables run here, separated safely from the core operating system. Riot Vanguard relies on vgk.sys, a kernel-level driver that executes within Ring 0.
Ring 0 is the innermost core of the operating system. Code executing in Ring 0 possesses unfettered access to system memory, hardware calls, and background processes. Riot engineered Vanguard this way to detect sophisticated, ring-level cheating software that hides from conventional user-mode anti-cheat systems. Furthermore, on Windows 11, Vanguard strictly mandates TPM 2.0 and Secure Boot.
This strict requirement creates an immediate dead end on macOS Sequoia. Apple’s Darwin kernel does not allow third-party software, especially code written for a foreign operating system, to inject itself into the macOS kernel. Apple has steadily locked down its kernel across the past decade, deprecating traditional Kernel Extensions (KEXTs) in favor of user-space System Extensions. Even if Riot wanted to build a native macOS Vanguard driver, Apple’s architecture denies third-party software the low-level hooks Vanguard requires on Windows.
