メモ。Gigazine記事 Macのチップが再びインテル製に？ https://t.co/AHS0Rnx0cc X86アーキテクチャに移ると言うのではなく、ArmアーキテクチャのチップをIntel工場で作るという話。トランプ政権対応らしい。 「Intel Inside（インテルはいってる）」と言えるのかな？

いろいろ大人の事情もあるらしい。Apple（アップル）が独自に設計する最新のM5ならびにA19チップは、ほとんどがTSMCによって製造供給されています。でも、ここにIntel（インテル）がApple向けにCPUの製造を請け負うという構図が加わってくる可能性を、著名アナリストのミンチー・クオ氏が明かしましたよ！ アップルとインテルが再び手を握る？いまはすっかり昔の話となってしまいましたが、Macに

The @surface UEFI feature to "sandbox" UEFI/SMM is open source and available for anyone to integrate. It includes support for QEMU. I would love to see this get integrated into @Dasharo_com or @coreboot_org tianocore payloads for increased security: https://t.co/JO9CAD7p4l

Windowsの新しい管理者権限保護「Administrator Protection」で、既存の「UAC Bypass」が難しくなりそうです。結構見逃されがちですが、Windowsが管理者権限を扱う方法が変わるので、マルウェア対策の観点では重要な変更です。（10月28日のWindows 11 24H2/25H2 向け KB5067036
