In my opinion, Apple’s opening keynote at its annual Worldwide Developer Conference (WWDC) in San Jose, California, was the best yet. Apple CEO Tim Cook and key Apple executives announced a slew of updates and product announcements including the latest tvOS, watchOS, iOS, iPadOS (yes!), macOS Catalina, and surprise… an all-new Mac Pro and accompanying Pro Display XDR. Here’s everything that was announced (that mattered).
macOS Mojave, the latest version of macOS is officially out as a free update for Mac users. The latest major desktop operating system release brings a plethora of new features including the much-awaited Dark Mode, a new Dynamic Desktop and nifty productivity features like Stacks. Apple has also brought over some familiar iOS app to the desktop including News, Stocks, Voice Memos and Home. There’s plenty to look forward to, but I’m listing 10 of my favourites which I think you’ll love, too.
Apple has quickly released a security patch to fix a flaw in macOS High Sierra that lets a user gain root access without a password. It had previously issued a temporary workaround to patch the vulnerability.

Actually, it’s more of a new instalment of solid software and hardware integration.
If you haven’t downloaded and installed it already, the Mac OS X 10.3.6 client and server updates are available for download from Apple servers.
