Mac Os High Sierra Will Not Load After Software Update

Cupertino, California — Apple today announced macOS High Sierra, the latest release of the world’s most advanced desktop operating system, is now available as a free update.
With macOS High Sierra, Mac users gain powerful new core storage, video and graphics technologies. A new file system ensures more efficient and reliable storage, and support for High-Efficiency Video Coding (HEVC) brings stunning 4K video at lower file sizes. Metal 2 powers virtual reality content creation, faster performance and more. The Core ML developer framework makes it easy to create apps with powerful machine learning that predict, learn and become more intelligent. macOS High Sierra also includes a number of refinements to the apps Mac users enjoy everyday, including Photos and Safari.
“macOS High Sierra is an important update that makes the Mac more capable and responsive, while laying the foundation for future innovations,” said Craig Federighi, Apple’s senior vice president of Software Engineering. “High Sierra introduces new technologies for VR, high-efficiency video streaming, advances in storage technology and more, while apps such as Photos, Safari, Mail and Notes are refined to give users even more reasons to love their Mac.”

Apple File System (APFS)

Some Mac users have reported technical issues once they update their OS to the High Sierra Update. To be precise, their App Store feature is not working as it should or at least, as it did before the update. Usually when an app releases its update, it is directly indicated in the App Store, but in this case, you get the update and when you proceed to download it, you get a pop-up showing “No Update Available”. But the Mac is not immune to errors and corruption on the operating system level. Many users have reported the same problem: Mac stuck on a login screen. In this case, the Mac won't let you log in, even you enter the correct password. And in some worse cases, the Mac computer won't even boot after the latest macOS update. Jun 22, 2018 But recently, a lot of readers and Mac users are finding the opposite–it just doesn’t work! Several users have recently had issues updating their MacBook with the latest version of macOS. Unfortunately, this appears to be a fairly common problem for some when updating to the latest macOS High Sierra update.
