MacOS High Sierra (10.13)

MacOS 10.13, which quietly switched the Mac's underlying filesystem to APFS — still a realistic target for genuinely old (2009-2010) Macs too old for anything newer.

High Sierra's headline change happened almost invisibly to most users: it migrated Macs from the decades-old HFS+ filesystem to APFS, Apple's modern copy-on-write filesystem, in the background during upgrade. It remains the newest MacOS many 2009-2010 Macs can run at all. Apple has hidden its Mac App Store listing from search, but the direct link to that same listing still works -- a real, if less discoverable, official download path.

Les dates de sortie, les périodes de support et la configuration requise proviennent des pages officielles de cycle de vie de Microsoft et d'Apple (liées ci-dessus) — vérifiez-y toujours avant de vous en servir pour une décision de déploiement en production ou en entreprise, les politiques de support pouvant changer occasionnellement.
