In iOS 13.4, you can share iCloud folders with other people for the first time. You’ve long been able to share a single file via iCloud, but now you can share folders, so all the people sharing can drop files in there. Just like Dropbox has done since, like, forever.

This new capability, which arrived Tuesday in iOS 13.4 and macOS Catalina 10.15.4, will finally let people ditch Dropbox and go all-in on iCloud. Let’s see how it works.

Macs everywhere can now upgrade to macOS Catalina 10.15.4. This adds iCloud Drive folder sharing as well as Apple Music time-synced lyrics and other enhancements.

The Up Next widget on the iPad home screen gets a handy tweak in iPadOS 13.4, showing the location of upcoming events if they’ve been specified in the Calendar. This is just one of the improvements in this version, which is still in beta testing,

But the release is getting closer, as Apple just released the third beta of iPadOS 13.4 to developers. Plus, there are new pre-release editions of macOS 10.15.4, iOS 13.4, tvOS 13.4 and watchOS 6.2.

SwitchGlass is a handy new Mac app from John Siracusa. It’s like a superpowered dock, conceptually honed from the regular macOS dock by removing some annoyances, and adding some extra subtleties. It’s certainly not the most powerful dock-replacement app out there, but if your needs align with Siracusa’s, then you’re going to love it.

Apple is working on a new software feature for macOS that can crank Macs’ processing powers into overdrive. References spotted by 9to5Mac in the latest macOS Catalina beta mention a new “Pro Mode.” Details on how Pro Mode will work remain hazy. However, a few lines of code hint that it might only be available on MacBooks.

Mac app developers that distribute their apps outside of the Mac App Store will have to submit their software to Apple’s notarization process starting in February.

Apple detailed the upcoming changes in a note to developers this morning. The company originally said developers would have until January 2020 to submit for notarization but the window has been extended a bit.

In macOS Catalina, iTunes has been replaced by separate apps, but none of those new apps takes on the tasks of syncing your music, books, photos and other data to your iPhone, iPod touch or iPad. That responsibility now falls upon the Finder.

So, does this means you can plug in your iPad and drag and drop all your apps’ files between it and your Mac? Of course not. In fact, apart from this functionality now being in the Finder, not much has changed at all.

In macOS Catalina, iTunes has disappeared. It’s been replaced by the new Music app, which is a version of the iOS Music app. You could never call iTunes “beloved,” but it did its job, and had plenty of power hidden inside its confusing and bloated interface. The Apple Music app, on the other hand, is rather basic. But it still lets you do one thing that remains impossible on iOS: You can add your own music to your library. And yes, it will then sync that music to your iDevices. Let’s see how.

macOS 10.15 Catalina is ruthless about launching unknown apps. Unless your app comes direct from the App Store, or the app’s developer got the app notarized by Apple, it won’t launch. Double click on it, and you’ll see a warning — and nothing else. There’s no option to say you trust the app and launch it despite Catalina’s warnings.

But you can still launch those apps. It’s just that Apple hides the controls in the hope that you’ll give up. It’s petty, and it shows a lack of respect for you, the user. However, it’s also dead easy to fix this problem. Let’s see how to launch any app on macOS Catalina.

You can sign a PDF on your Mac using the giant MacBook trackpad, and you can mark up PDFs and screenshots, too. But all that stuff is much easier on the iPad, especially if you have an Apple Pencil. The problem is getting it there. But in macOS Catalina, you don’t have to “get it” anywhere. Screenshots and PDFs magically show up on nearby iPads, where you can sign them or mark them up. Then you can return them to your Mac. These features are called Continuity Sketch and Continuity Markup, and they’re killer.

You know how the UPS guy holds up his brown scanner box for you to sign? PDF markup is like that, only on your iPad — and you never feel guilty about ordering too many parcels.
