Perhatikan bahwa saya melakukan tindakan yang salah dengan mengubah izin secara global di folder var. Setelah menginstal ulang sistem, masih ada masalah untuk membuka file dmg The DiskUtility mengumumkan masalah berikut:
Permissions differ on "private/var/db/ConfigurationProfiles"; should be drwxr-xr-x ; they are drwsr-s--T
Warning: SUID file "private/var/db/ConfigurationProfiles" has been modified and will not be repaired
Permissions differ on "private/var/db/SystemPolicy"; should be -rw-r--r-- ; they are -rwsr-s--T
Warning: SUID file "private/var/db/SystemPolicy" has been modified and will not be repaired
Permissions differ on "private/var/db/launchd.db/com.apple.launchd"; should be drwxr-xr-x ; they are drwsr-sr-t
Warning: SUID file "private/var/db/launchd.db/com.apple.launchd" has been modified and will not be repaired
Permissions differ on "private/var/db/locationd"; should be drwxr-x--- ; they are drwsr-s--T
Warning: SUID file "private/var/db/locationd" has been modified and will not be repaired
Permissions differ on "private/var/yp/binding"; should be drwxr-xr-x ; they are drwsr-s--T
Warning: SUID file "private/var/yp/binding" has been modified and will not be repaired
Setelah secara hati-hati mengatur ulang izin dengan tangan karena DiskUtility tidak akan melakukannya sendiri (mengapa?), Masalah saya terpecahkan.
Jadi saya tidak setuju dengan apa yang ditulis di mana-mana: pesan itu penting, dan jika Anda mendapat izin yang buruk di suatu tempat, Anda harus memperbaikinya ..
