Mac – Mysterious permission denied

macpermission

I am trying to save a file but get the error message saying file could not be saved. This happens only after the first time I save a new file. That means, if I create a new file saving works. BUt if I try to save the second time, I get the error message.

I also see this error in the Console. Omnigraffle is the application I am trying to save with. I have tried to set the permission on /.vol with no effect.

3/22/12 11:28:06.201 AM [0x0-0x6c06c].com.omnigroup.OmniGrafflePro: [ERROR] genstore_storage.c:GSAddPathAsGeneration:980  copyfile "/Users/xman/gfx/process.graffle" to "/.vol/234881026/2/.DocumentRevisions-V100/staging/adding.gdpTISed/14F74540-E254-4B92-A8EE-B857FD311DB6.graffle" failed with error 13 (Permission denied)

Additionally, I cannot install the new version of Xcode. Not sure if it is relevant or not, but it fails with a generic error.

Omnigraffle attempts to save its files as packages - a format OS X supports, but windows and samba servers do not.

There is an "save this document as a flat file" preference option for each document in Omnigraffle which should resolve this issue and should be used if you regularly save to network shares on non-Apple servers.

You'll need to change the document properties for each document you wish to save this way:

You can go in to the Inspector for the document, and look in the Canvas accordion pane under the Document Settings tab. There, you will find a heading for "File format options", which by default seems to be set to "Automatic." You can change this to "Save as flat file", and save the document

If you need to do this often, you can change the document templates so that any new documents you create will automatically be flat files:

Go to the OmniGraffle application bundle, right-click, and select "Show Package Contents."

Finder will show you the inside of application bundle. Navigate within the application bundle to Contents => Resources => Templates. In here, you will find a set of OmniGraffle documents that are used as your default document templates.

Open the document template that you want to modify. OmniGraffle launches and shows you the document.

Open the Inspector for the document, go to Document Settings under Canvas, and set the document template file's File Format option to "Save as flat file."

Save the document template.

Now, all new OmniGraffle documents created from that document template will also have their default preference set to "Save as flat file" since the template's preference has been set to that setting.

MacOS – Can’t save files in some applications

Since you haven't used ls -le as recommended, we don't know what the access control list looks like, but there might be something going on there that is preventing you from being able to write the files. The fact that a newly created user CAN edit the files makes me even more suspicious.

This command will remove ALL access control list entries from the folder and all its subfolders and files:

sudo chmod -RN path/to/folder/containing/files

Once you've cleared the access control list, try resetting the ownership like so:

sudo chown -R ulrikdamn:staff path/to/folder/containing/files

Now grant permissions like so:

sudo chmod -R u+rwX,g+rX,o+rX path/to/folder/containing/files

This gives you full read/write permissions. The "staff" group and all other users get full read permissions. Using an uppercase X, sets the execute bit for all directories within the tree, but leaves the execute bit for regular files as is.

Lowercase x would set the execute bit for all folders AND files. The execute bit must be set for a directory in order to read its contents. If you'd like to give write permissions to the group or others, switch out for g+rwX or o+rwX as necessary in the last command.

Here I'm passing in a folder path. If you want to pass in a single file, just remove the -R from each command. The R makes the command recursive, applying it to an entire directory tree. Without it, the command will modify the permissions for a single file or folder passed in.

I had the same problem. I tried what Matt Love has suggested and still had the problems. I then downloaded Cocktail and ran permission repair, rebooted and all worked again.
