Catalina is a real dividing line for older software compatibility: it's the last MacOS release that could run 32-bit-only applications at all, which makes it a deliberate choice for people keeping specific old professional software (older audio plugins, older CAD/engineering tools) alive on genuinely still-used older Intel hardware, rather than something to upgrade past. Its Mac App Store listing remains a real, currently working official download.

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.
