What's new in this version:

- This version responds to a very critical security flaw found in current versions of macOS High Sierra. TinkerTool System will automatically detect upon each start whether system security has been compromised on your Mac as result of this issue. If this is the case, the application will automatically direct you to a web page with instructions from Apple that can be used as a workaround
- The feature to automatically warn the user if the root account of the operating system has permission to log in was modified due to a known security defect of macOS High Sierra
- Fixed a problem where the processing of group memberships of a user could fail if the user was in more than 16 groups
- Fixed a problem where TinkerTool System could not create install media for older operating systems when running macOS High Sierra
- Fixed a problem where the application could crash in very rare cases when using multiple features of the pane Clean Up subsequently
