On April 10, 2023 (early morning of the 11th, Beijing time), Apple released macOS Big Sur 11.7.6 and macOS Monterey 12.6.5 security update versions (sysin) for old Macs that cannot update macOS Ventura. Apple released new versions of iOS 16.4.1 and macOS Ventura 13.3.1 last Friday, which fix the oft-exploited vulnerability, and today's software update addresses the same issue on older devices, and also includes the updated iOS 15.7. 5.

macOS Big Sur takes power and good looks to a whole new level. The carefully crafted new design allows you to fully experience the charm of Mac; the Safari browser has ushered in a major update, waiting for you to enjoy it; the map app and information app are full of new features for you to explore; more transparent privacy permissions, protection also more thoughtful.
