This takes into account that Apple’s installer is based on working with volumes (not disks) whose formatted capacity can be significantly lower than that of the physical storage device. The feature to create macOS installation media now accepts destination volumes which have slightly less than 8 GB of storage.The following features no longer make sense in macOS Recovery Mode and have been removed: file system check for the system volume, deleting Input Managers, rebuilding XPC caches, self-removal. A graphical interface to disable or enable System Integrity Protection has been added to the emergency tool.Separate, proactive installation steps for the emergency tool are no longer necessary.
Compatibility with present and future versions of macOS is improved, because Single User mode is no longer officially supported by Apple.The new “TinkerTool System for Recovery Mode” (ttsfrm) supersedes the previous emergency utility. The standalone version of TinkerTool System (tts in Single User mode) has been rewritten completely.Added further support for future versions of macOS.
Added new feature to resize disk images (DMG files), hereby avoiding the flaws of Disk Utility.
