Question

repair the disc permissions

Why, since when I installed the OS Yosemite, in my MacBookPro8,2, I must repair the disc permissions every week?

This is the report:

Repairing permissions for “Macintosh HD”Warning: SUID file “System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAg ent” has been modified and will not be repaired.Group differs on “Library/Printers/InstalledPrinters.plist”; should be 80; group is 0.Permissions differ on “Library/Printers/InstalledPrinters.plist”; should be -rw-rw-rw- ; they are -rw-r--r-- .Repaired “Library/Printers/InstalledPrinters.plist”User differs on “private/var/db/displaypolicyd”; should be 0; user is 244.Group differs on “private/var/db/displaypolicyd”; should be 0; group is 244.Repaired “private/var/db/displaypolicyd”

As long as the report ends up with 'Permissions repair complete' then, as far as permissions go, you are fine. You can ignore the various statements in the report:

Permissions you can ignore on 10.5 onwards:

Using 'should be -rw-r--r-- , they are lrw-r--r--' as an example, you will see the that the permissions are not changed, but the | indicates a different location. This is because an update to Leopard onwards changed the location of a number of system components.

Poster rccharles has provided this description of what it all means:

drwxrwxrwx

d = directory

r = read

w = write

x = executeable program

drwxrwxrwx

| | |

| | all other users not in first two types

| |

| group

|

owner

a little more info

Before the user had read & write. A member of the group had read.

After, only the user had read & write.
