The launch of macOS High Sierra, was the end of iTunes as we knew it until now, since Apple completely removed any trace of the App Store, forcing the user rely solely on the iPhone, iPad, or iPod touch to download and purchase your favorite apps.
Apple began to prepare the ground a couple of years ago, when Apple removed the option that allowed us transfer the applications purchased in our terminal to the PC or Mac, so we had to download them manually through iTunes if we wanted to have a physical copy of the game or application in case Apple or the developer removed it from the App Store.
Fortunately, Apple did not think well of this Solomonic decision, since the business or educational sector needs iTunes to be able to install school or company apps, proprietary applications that are not available or will be at some point in the App Store.
In order to satisfy these companies, Apple offers us a version of iTunes prior to 12.7 with which we can continue to enjoy the same functions that it offered us until the launch of macOS High Sierra. This app also can be downloaded by any user you want to retrieve those functions.
For now that special version has not received any new updatesHowever, the new version of iTunes has received two updates, the last one has number 12.7.2, an update that focuses on improving the performance of the application in addition to improving the bugs that have been found since it was launched the previous version.
Hopefully the guys from Cupertino keep updating the iTunes version that allows us to continue enjoying the functions we were used to since the launch of the App Store.
