ARM64 Enhanced Memory Tagging Extension #EMTE exploit mitigation now exists on:

- iPhone 17e, 17, 17 Pro, and Air
- iPad Pro M5
- Macbook Pro M5, Air M5

EMTE is on-by-default, always-on, and no performance hit. Even without Lockdown Mode, this is arguably one of the most secure (internet connected) devices in the world. The 17e priced at 599 US, 719 EUR is kind of incredible.

If you're an at-risk individual, sincerely look at the 17e.

For critical work, such as journalism + sources, legal + clients, politics, activism: you can't beat the iPad Pro M5 Wifi version. I've been maintaining a detailed blog post about the iPad Wifi for years:

"#Exclaves land in MacOS

Nobody is really surprised that the MacOS 26.0.1 firmware image of the about to be released MacBook Pro #M5 reveals that Memory Integrity Enforcement (#MIE) on top of the ARM64 Enhanced Memory Tagging Extension (#EMTE) is used. Extremely surprising is however that Apple is now shipping the Secure Kernel (#SK) and #ExclaveCore / #ExclaveOS with MacOS. This means Apple's newest security boundary #Exclaves has finally arrived in MacOS."
