When Mac folders or files greyed out and were inaccessible, your Mac could detect the error and set the date the Macintosh was first introduced, January 24, 1984. How could I fix grayed out folders or files on Mac without data loss and damage?' Did it mean those files were created on that date? That's ridiculous.

'I managed to transfer some photos and videos from an old Seagate external hard drive to my Mac, but they all grayed out and couldn't be accessed! By the way, the grayed out folders and files reported an error 24 January 1984. Why my folders and files greyed out on Mac? To restore the lost folders and files, run EaseUS Mac data recovery software, scan device. Open Finder > Locate the greyed out folder or file > Go to Application > Open Terminal.
