1/ Change the Playlist pictures in iOS Music — By default, playlists within the Music app use the albums’ artwork as their identifying image. But you can take a picture to use or grab one from your Photos library: here’s how on iPhone/iPad.
Open the Music app, and then click on the Library tab to visit the Playlists section.
Touch the one you’d like to change the picture on, and tap the Edit button at top right on the subsequent screen.
In this editing mode, you’ll see a small photo icon appear on the playlist’s image at top left – tap that.
You’ll be given an option to either take a photo or choose one from your library.Choose, or take, and tap Done to finish the job.
The change will sync to your other devices if you’re using iCloud Music Library. Cool, right?
2/ Use your Apple Watch to auto unlock your Mac — Apple added a feature in macOS Sierra and watchOS 3 called Auto Unlock. This lets you automatically unlock your Mac by waking it up. It’s handy to use and easy to set up if you have an Apple Watch running watchOS 3 and a mid-2013 or newer Mac running macOS Sierra 10.2 or newer.
First you’ll need to set up two-factor authentication for your Apple ID, as this doesn’t work with two-step verification. Apple has a support page to switch from verification to authentication (Mac Observer has an article on setting up 2FA here).
Once that’s set up, turn on Bluetooth and Wi-Fi on your Mac. You’ll also need to be signed into your Watch and Mac with the same Apple ID and your Mac can’t be using Internet Sharing. Check to make sure in System Preferences > Sharing. Next, go to System Preferences > Security & Privacy.
Both your Mac and Apple Watch need to be set up with a passcode. On your Watch, go to Settings > Passcode > Turn Passcode On. On your Mac, go to System Preferences > Users & Groups > Change Password.
Now on your Mc, click on the Apple icon () in the upper left corner of your screen.
Click System Preferences > Security & Privacy > General.
Check the box next to Allow your Apple Watch to unlock your Mac.
It will take a couple of seconds to activate. Now, the next time you need to wake up your Mac, Apple Watch auto unlock will automatically unlock it. It’s just magic.
3/ Ditch the Honeycomb App Grid in watchOS 4 — Along with the Developer Beta 1 of iOS 11, Apple also recently released the first preview version of watchOS 4. This developer beta (so still not generally available to everyone) brings some under-the-hood enhancements, new watch faces and more intelligence and fitness features. It also includes something that wasn’t announced – you can now ditch the awkward honeycomb app grid and instead get a list of your installed apps:
Press the Digital Crown to get to your Apple Watch Home screen. Then, Force Touch the screen and a brand new configuration panel shows up.
Choose between grid view or list view.
Once you’ve made the switch, you can scroll normally through your apps in a list, sorted alphabetically. You can also rotate the Digital Crown to move through your apps, which are sorted alphabetically.
There isn’t any way to rearrange your apps in List View, at least for now. Bear in mind, though, this is still only Developer Beta 1 of watchOS 4 so more changes may be yet to come in future beta versions of the wearable operating system. The developer beta is available now, and the full release is expected in northern autumn 2017.
(It’s also worth noting that watchOS 4 will leave some iPhone owners out in the cold. It requires a paired iPhone 5S or later with iOS 11 to download and install. This is because Apple has removed 32-bit device support in iOS 11. Devices like the iPhone 4S, iPhone 5, and iPhone 5C are only 32-bit devices, so they aren’t supported by the latest version of the operating system.)
4/ iMazing — You know how getting files off an iPhone or iPad onto a Mac can be a mission, mostly because AirDrop only works sometimes? An app for macOS called iMazing changes all that. It’s not cheap though: a single license for iMazing costs US$39.99, a universal license is US$49.99, or you can get five licenses US$69.99 (for both Windows and Mac). all you need to do to unleash this power is plug your iPhone/iPad into your Mac with the charge cable (since it’s USB at the end that goes into the power charger). For example, via iTunes, it’s easy to transfer music from Mac to iPhone or iPad. What if you want to export tracks off your iOS device? That’s not possible in iTunes, but it’s a snap with iMazing: select the media files you want, whether they’re songs, movies, TV shows, podcasts, or audiobooks, then click Export to Folder, and iMazing will happily transfer them to your hard drive. It’s even smart about it, recognising the tracks you already have in iTunes and leaving them alone.
5/ Archive and even print Messages — If you want to save your text messages and iMessage conversations to your desktop, or even print them, with iMazing you can. It doesn’t matter if you want a PDF, text document, comma-separated values (CSV, like a spreadsheet) file, or a full printout of your messages, this app can handle it. You can also export attachments separately, for those times when you want to get a bunch of images out of your text message history.
