Problem

Suddenly, after rebooting a Snow Leopard Mac Pro (2009), I cannot copy to the main disk, or even move one of its files, without having Mac OS X asking for authentication.

Once I type the password in the dialog box, the copy is made, but this is not acceptable nor usable in the long term. I even think most apps won't like it...

enter image description here

I'm talking about copying a file from the Desktop to somewhere else on the same disk, the one the system has booted on...!

History

2 x Mac Pro 2009, one has Mac OS X 10.6 Snow Leopard working properly, the second one has nothing.

I used Copy Carbon Cloner to make a clone of the first Mac on another disk then installed the copy in the second machine.

It worked for some time! Then, on this second Mac, I added another disk in bay 3 and things started to go south. I think the disk in bay 3 was faulty.

So I stopped the machine, removed the faulty disk from bay 3, and rebooted. And here the authentication problem on the main disk appeared.

What has been done

I've booted from another system partition on another disk then used Disk Utility to repair the disk and to repair permissions. No errors were detected.

I researched other answers to similar questions but they are all about using an NTFS disk, and this is not my case at all, I'm talking about a standard HFS+ Mac OS X disk that suddenly is in this "read only" mode.

Other info

If I add another disk with Yosemite installed, I can boot on it and I can copy/move/write anything on the Yosemite disk and on the Snow Leopard one.

But I absolutely need to have the Snow Leopard one also working (because of obsolete apps we still need) and rebooting again on it, the problem is still here.

TL;DR

In a 2009 Mac Pro, a cloned Snow Leopard disk asks for authentication for any file operation.

In the same Mac Pro, a Yosemite disk works properly and does not suffer from this issue, I can move files on the Yosemite disk and on the Snow Leopard disk.

Back on the Snow leopard one: the authentication problem is still here, for all disks in the machine.

  • Try cd ~; ls -ale | grep -e '^ [0-9]*:' -B 1 | grep -v '^--$' in the Terminal -- does it give any output? Mine has 0: group:everyone deny delete on several folders, but I'm wondering if there's one preventing you from modifying things at all (like deny write or something). – SilverWolf - Reinstate Monica Oct 17 '17 at 15:26
  • What this does: cd ~ moves to your home folder, ls -ale lists the files, and the greps filter for ACLs and remove -- separating lines, respectively. – SilverWolf - Reinstate Monica Oct 17 '17 at 15:27
  • I just realized I didn't explain ACLs -- it means "Access Control List", and specifies who can do what with a file, independently of permissions. This lets you do things like give specific users access but deny other people. – SilverWolf - Reinstate Monica Oct 17 '17 at 15:30
  • @seaturtle Thanks. Running this command lists the main folders (Desktop, Documents, Downloads, etc). It also gives me "0: group:everyone deny delete" on all folders! Is this the issue? – ayaio Oct 17 '17 at 15:32
  • Please add - booted to the misbehaving SL - the output of sudo ls -lae / and sudo ls -lae ~/ entered in Terminal to your question. – klanomath Oct 17 '17 at 15:32

Do this instead:

Open Finder, find your drive, typically named "Macintosh HD"(but in your case "MAC106"), select it, press Command (⌘) + I on your keyboard, in the window that opens, scroll to the bottom, if the text next to your username is "read and write", this isn't the solution, but if the text is "Read Only", do this:

Click the padlock, type your credentials, click the "Read Only" tag next to your username, click on "Read & Write", click on the padlock, and done.

  • There's system: read/write, wheel: read/write, everyone: read. – ayaio Oct 18 '17 at 7:58
  • Okay, unlock the padlock, click on the + button, click on your username, click on the blue add button, and then set your account to “Read & Write” as mentioned in my answer above. – Harcker Oct 18 '17 at 8:42

    Looks like it solved the issue! Thanks a lot!!! :) – ayaio Oct 18 '17 at 8:46
  • You just have to be aware that this will give any application you run access to the root of the disk... – Harcker Oct 18 '17 at 9:09
  • Good to know. Not an issue for this machine (it's not connected to Internet and nobody installs anything on it but me). Thanks. – ayaio Oct 18 '17 at 9:10

Before you do this, always make sure you have a recent backup!

Is your problem only at the root level, or in every folder?

If it’s in every folder try this solution, it’ll remake all file permissions: launch the Terminal from /Applications/Utilities/, type this command: sudo chmod -RN ~/Desktop, press enter, type your password, and press enter again. Wait for the command to finish (it can take some time).

If this makes you able use your desktop as Read/Write, you can try doing this sudo chmod -RN /, it’ll do the same but for the whole disk instead.

Before you do this, always make sure you have a recent backup!

    Nice, didn't know about chmod -N. I'd just like to point out, though, that OS X ships with ACLs on Desktop, Documents, etc. as well as the home folder, and this will probably remove them. The -N doesn't remake all permissions, it removes ACLs (which can still be helpful, it's what I was getting at in my comment). – SilverWolf - Reinstate Monica Oct 17 '17 at 15:29
  • Is your problem only at the root level, or in every folder? Mm, I didn't notice that before: only at root, it seems. I just created a folder on the Desktop and in Documents successfully. – ayaio Oct 17 '17 at 15:50
  • okay, if so, don't follow my answer, – Harcker Oct 17 '17 at 16:09
