Plus pr\u00e9cis\u00e9ment pour macOS Sequoia 15.8, Apple a fourni un correctif suppl\u00e9mentaire pour le cadre graphique ImageIO. Les \u00e9quipes de s\u00e9curit\u00e9 qui ont d\u00e9couvert les vuln\u00e9rabilit\u00e9s comprennent OpenAI Codex Security, NVIDIA AI Red Team et Anthropic Research.<\/p>\n<h2>Maintenance pour les anciens syst\u00e8mes et adieu aux Macs Intel<\/h2>\n<p>Avec macOS Tahoe 26.7 et Sequoia 15.8, la soci\u00e9t\u00e9 continue de maintenir des g\u00e9n\u00e9rations de mat\u00e9riel plus anciennes qui ne peuvent ou ne devraient pas \u00eatre migr\u00e9es vers de nouvelles plateformes. Les deux versions renoncent enti\u00e8rement aux nouvelles fonctionnalit\u00e9s d&#8217;interface utilisateur, se concentrant strictement sur les corrections de bugs et les correctifs de s\u00e9curit\u00e9. Par contre, l&#8217;ancien macOS Sonoma n&#8217;a re\u00e7u aucune mise \u00e0 jour dans ce cycle de diffusion.<\/p>\n<p>Dans le m\u00eame temps, le nouveau macOS 27 Golden Gate marque un tournant notable dans la strat\u00e9gie de plate-forme d&#8217;Apple : cette 23\u00e8me version majeure est la premi\u00e8re \u00e0 soutenir exclusivement les machines aliment\u00e9es par des processeurs Apple Silicon. Les anciens mod\u00e8les \u00e9quip\u00e9s de puces Intel ne sont plus pris en charge par cette g\u00e9n\u00e9ration. Golden Gate comprend environ 206 correctifs de s\u00e9curit\u00e9 et, avec des raffinements visuels, introduit une int\u00e9gration plus profonde de Siri pour Apple Intelligence ainsi que le support pour le MacBook Neo (2026).
