If you’re running macOS 10.12 Sierra or earlier, and do not wish to upgrade to macOS 10.13 High Sierra, be careful as Apple is now downloading High Sierra update automatically to your Mac in the background, making it all too easy to upgrade inadvertently.
This is a change of behaviour from Apple. In the past, only minor changes or security updates are forced into users like that. Apple explained this change in its support article:
If you’re using OS X El Capitan v10.11.5 or later, High Sierra conveniently downloads in the background, making it even easier to upgrade your Mac. When the download has completed, you receive a notification indicating that High Sierra is ready to be installed. Click Install in the notification to get started.
If you want to install High Sierra later, just dismiss the notification. Install it at any time by opening the file named Install macOS High Sierra from your Applications folder, Launchpad, or Spotlight. Or delete the installer by dragging it to the Trash. You can always get it again from the App Store.
Please note that this ‘convenience’ imposed by Apple is an automatic download of a 5.21 GB Installer in the background. Apple does not bother if you have limited disk space or bandwidth for the download. This could cause users some extra telco fees without them agreeing.
Please note that even if you’ve configured your Mac to prevent downloading updates in the background, the High Sierra Installer will still be forced into you.
If you’re not ready to upgrade to High Sierra, you may want to search under the Applications folder and remove the large “Install macOS High Sierra” file.
macOS High Sierra, together with iOS 11, are the most unpolished releases from Apple in recent years. It is advisable to upgrade to them when their .2 versions are released. Wait for macOS 10.13.2 High Sierra and iOS 11.2.
If you’ve been using iOS for a few years, you might notice that Apple has tuned up system animations up a little in iOS 11. This is Apple saying it has a brand new animation library and want you to take notice.
Some people might find the animation annoying. Good thing is there is a setting for you to reduce the motion.
Goto Settings app > Accessibility > Reduce Motion and turn on the “Reduce Motion” switch. You will notice opening and closing apps are now almost instantaneous. Try it out, you might prefer the less motion setting.
iOS Restrictions is build for the use case when you want to restrict usage of phone features when someone else is using your phone. It is very useful for example to restrict “In-App Purchases” while your kid is using your phone for some games.
You can however use Restrictions for yourself by hiding unused system apps from the home screen. For example to reduce web browsing time or you use primarily other browser, you can hide Safari. If WhatsApp or Facebook Messenger is your video chat apps, you can hide the FaceTime app. Or hide the Podcasts app and use one from third party developer. Sometimes disabling “In-App Purchases” for yourself is a good choice when self-control is not enough.
To use it, go to Settings app > General > Restrictions. Tap “Enable Restrictions” to switch it on, and iOS will prompt you for a passcode to access this settings.
Simply turn off the switch to disable the feature you want. Not all Apple apps are available for you to disable. If you like your home screen tidy, go ahead and hide some unused apps and features.
