Grayed out folders and files show the ’24 January 1984′ error, meaning they are all dated with 01/24/1984.
SMB Windows file sharing not working on Mac after upgrading to macOS 10.13 High Sierra or macOS 10.12 Sierra or setting up a new Mac or MacBook via iCloud is easily fixed. For SMB windows file sharing, you need to select a user for activation. Sometimes, you cannot select the user because the user is grayed out. The real cause of this problem is that you most probably use the same password for accessing your Mac and as your iCloud password. Due to security reasons, you cannot use the same password for both your Mac and iCloud anymore. This fix also applies to Mac OS X 10.11 El Capitan.
