Long ago, Apple used a file system called HFS+. As it was already a venerable file system, it took decades for the tech company to update it. It was only in 2017 when Apple finally released an updated version of the HFS+ that sported improvements to encryption, space allocation, and file integrity. It was aptly named the Apple File System or APFS.

While the new file system seemed perfect, some end users have run into unexpected issues and incompatibilities. One of which is the error 49153.
