我还没有看到确认这一点的报告（仅针对A19芯片），所以我刚刚购买了一台新的M5 MacBook Pro 14英寸，并执行了以下操作： ``` $ sysctl -a | grep MTE4 hw.optional.arm.FEAT_MTE4: 1 ``` MTE4是“增强内存标记扩展”[1]，它是苹果更广泛的内存完整性强制系统的基础。关于内存完整性强制（MIE）及其重要性的更多信息，请访问：https://security.apple.com/blog/memory-integrity-enforcement/ [1] https://developer.arm.com/documentation/109697/0100/Feature-descriptions/The-Armv8-9-architecture-extension?lang=en#md454-the-armv89-architecture-extension__FEAT_MTE4

I haven't seen reports confirm this (only for the A19 chip) so I just bought a new M5 MacBook Pro 14" and did this:<p><pre><code> $ sysctl -a | grep MTE4 hw.optional.arm.FEAT_MTE4: 1 </code></pre> MTE4 is the "enhanced memory tagging extension"[1] that underlies Apple's broader Memory Integrity Enforcement system.<p>More on MIE and why it's cool: https://security.apple.com/blog/memory-integrity-enforcement/<p>[1] https://developer.arm.com/documentation/109697/0100/Feature-descriptions/The-Armv8-9-architecture-extension?lang=en#md454-the-armv89-architecture-extension__FEAT_MTE4
