Enlarge / No working system is an island, however macOS Catalina is known as after one.
Ever because the iPhone got here out in 2007 and virtually instantaneously overshadowed the Mac, each when it comes to gross sales and improvement sources, Apple has been making the Mac a bit extra just like the iPhone. Certain, a number of options have moved the opposite means—the iPad has steadily gotten a bit extra Mac-like because it has develop into highly effective sufficient to do Mac-like issues—however a giant piece of each macOS launch this decade has been “here is all of the stuff Apple introduced over from iOS this yr.”
Catalina strikes macOS additional and extra decisively within the course of iOS than ever; for the primary time, third-party code written for iOS and iPadOS can run on the Mac with comparatively few adjustments. On the similar time, Apple stays adamant that the Mac and iOS/iPadOS are separate platforms that differ in ways in which transcend the underlying processor structure or the first enter mechanism.
Catalina additionally attracts clearer traces between the 2 platforms than we have gotten earlier than. Apple has each mentioned and accomplished issues that solely make sense if the Mac will nonetheless have the ability to run no matter code you need for the foreseeable future, even because the default settings and safety mechanisms develop into extra locked-down and iOS-y. The overwhelming success of the iPhone signifies that most individuals are advantageous with Apple’s restrictions more often than not. However the slew of latest desktop hardware we have gotten within the final couple of years means that Apple understands helpful, vocal chunk of the Mac consumer base (and the builders who drive the iPhone’s and iPad’s success) nonetheless desires highly effective hardware that runs extra versatile software program.
Regardless of continued angst about what it means for apps to be “Mac-like,” the Mac will proceed to be the Mac, distinct from the iPhone and the iPad. Maintain that in thoughts as we dig into Catalina, which adjustments an entire lot of stuff about how Macs work whereas nonetheless aiming to protect what individuals like about them.
