Resolved - temporarily: Group 80 and 0 - 10.9 install

[davidlv]

After booting from the Recovery partition, and running Repair Permissions from Disk Utility, the issue below no longer appeared. For a while, now its back.
Running Repair Permissions with Mavericks 10.9 produces the following results.
“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”

What is the meaning of “Group should be 80, is 0”?
Disk Utility says it repairs the file, but it gets the same error every time.
Is this something to be concerned about? Should I just try deleting the file and then reinstalling my printer driver (Canon)?

Got the same issue on 10.9, and I have no printers at all/none installed. Methinks it's yet another bug.

I get same OP with a Canon Printer installed. I'm not concerned since everything else is working fine including the Printer.

Got the same issue here and I have no printer installed. I guess it's just another bug.

Feel free to ignore it, it's meaningless. Mysterious stuff like this happens all the time and never affects anything.

Glad your problem has been resolved. I'm not sure why that particular file has the wrong permissions, but I can explain what the DU explanation means. Group 80 is the UNIX Administrator (admin) group and group 0 is the "wheel" or root group (equivalent to when you use "sudo" in Terminal.app). All users with administrative privileges are in wheel, so the "error" that DU is reporting is kinda moot. See Disk Utility's Repair Disk Permissions messages that you safely ignore.

get the same thing - and it does not affect anything. Be thankful that permission repair only flags this issue. It's nothing...really...

ANSWER: InstalledPrinters.plist”; should be 80; group is 0.

I found a way to get rid of the permission error:

I went to Computer/Library/Printers and found the file called "InstalledPrinters.plist". Select file and press "command i" (to get info). On the bottom of the info box is a lock: I unlocked the file. The next time I repaired permissions, the error was gone!

Unfortunately that was not the case with my MBP.
This may actually be a non-issue, as the printer works fine even when that error appears.
I checked the Get Info pane, the file was already unlocked, but only the system had read and write permissions, so I changed that so wheel had read and write permissions too. Following that change DU doesn't spit out that error! On another Mac, Macmini 2011, Everyone also had read and write permissions, and no error in DU.
This may be the simple fix required.

Unlocking the file just allows you to change permissions. What I discovered is that the file is set to "Read Only" for both "Wheel" and "Everyone". If you run Disk utility, it changes both of those to "Read/Write". Manually changing them from the Get Info window will resolve the issue, even though it's really nothing to be concerned with.
