Reply To: Diagnostic query: Unexpected kernel panic on macOS Sequoia 15.1 after waking (1794661940)

[Nina Patel]

A recent IOPlatformPluginFamily panic signature matches a known race condition in the X86PlatformPlugin/AppleSMC handoff when a TCC (Transparency, Consent, and Control) daemon holds a power assertion during snapshot mounting—common with third-party endpoint security agents hooking fileproviderd. Audit active assertions via pmset -g assertions | grep -E "(PreventUserIdleSystemSleep|ExternalMedia)" and temporarily uninstall any kernel-level security sensor (CrowdStrike, SentinelOne, etc.) to isolate the kext. If the panic ceases, engage the vendor for a Sequoia 15.1-compatible sensor build addressing the IOPMrootDomain lock ordering regression.
