Apple’s move of dropping support for the iOS App Store with iTunes 12.7 let to it receiving a lot of flak. The move essentially meant that iPhone and iPad owners had no other way of downloading apps other than using the App Store on their devices. Now, in a move likely aimed to please its enterprise owners, Apple has silently released iTunes 12.6.3 with support for iOS 11, iPhone 8, and iPhone X.
This new version of iTunes also allows users to download apps from the iOS App Store on their PC and then install it on their devices at a later point.
iTunes 12.6.3 supports macOS High Sierra, Sierra, El Capitan, and Yosemite. If you have already installed iTunes 12.7 on your Mac, worry not as Apple is allowing users to install iTunes 12.6.3 on top of it. However, post the downgrade, your existing iTunes library will not be compatible with the downgraded version. You will have to create a new library to bypass this problem. This can be done by holding down the Option key while launching iTunes and selecting the “Create Library” option from the box that pops up.
Post installing iTunes 12.6.3, the Mac App Store will no longer show iTunes 12.7 as an update. In case you want to ‘upgrade’ back to iTunes 12.7, you can do so by manually downloading the installer from Apple’s website.
Apple has likely released iTunes 12.6.3 after receiving negative feedback from its enterprise customers. Its unclear as to how long the company will be supporting iTunes 12.6.3 or whether it would offer its functionality in a future version of the app or not.
