Apple Catalina Upgrade



Apple has just dropped the new version of macOS, macOS Catalina, which was introduced back in June during the WWDC 2019 keynote. And like previous years, many users are looking for direct download links for macOS Catalina, rather than going the usual route via System Preferences or the Mac App Store (MAS). You can now submit apps built with Xcode 12.5 beta 3 using the SDK for iOS 14.5 beta 3, tvOS 14.5 beta 3, watchOS 7.4 beta 3 for internal and external testing. Catalina is the 15th release of what Apple used to call OS X, and like earlier versions, it builds on a solid and secure Unix-based foundation. Catalina runs smoothly and reliably and adds several.

macOS Big Sur elevates the most advanced desktop operating system in the world to a new level of power and beauty. Experience Mac to the fullest with a refined new design. Enjoy the biggest Safari update ever. Discover new features for Maps and Messages. And get even more transparency around your privacy.
