I am having an issue with Lion OS X 10.7.5 on both my MacBook Pro and iMac.

When trying to copy an .rtf file from iMac to MacBook Pro, over the network, and vice versa, I get the message that "Finder wants to make changes. Type your password to allow this."

Below this message window is another window showing a swirling progress bar and states "Preparing to copy to "desktop" and the name of the file.rtf I am trying to copy to the target machine. Simultaneously the .rtf icon and name of the file appears on the target machine desktop (which is the destination for the file to be copied) but the .rtf icon is empty (zero bytes) and cannot be opened.

So I ignore this and continue. When I submit my password I am then met by a message stating that, "A newer item named "xxxxxxx.rtf" already exists in this location. Do you want to replace it with the older one you're moving?" and I am given the 3 choices of "Keep both files" or "Stop" or "Replace".

If I chose "Keep both files" then over 6000 copies of the .rtf file appeared on the desktop of the target machine and the only way I can stop the copies being reproduced is by turning off Airport. Clicking the "Stop copy" only leaves the message that it is "stopping", but it does not, and the progress bar continues swirling and producing an infinite number of copies on the target machine until I turn off Airport.

If I choose "Replace" I get the message "The operation can't be completed because an item with the name """" already exists." and gives me no choice but to click OK.

The .rtf icon and name of the file on the source machine contains 1453 bytes but on the target machine the .rtf icon looks different and contains zero bytes and cannot be opened. The same goes for all the over 6000 copies that had been produced on the target machine. It is as if the outer shell of the file is copied but not the content!

I also have a Macbook running OS X 10.6.8 and there is no issue between MacBook Pro and Macbook, and there is no issue between iMac and Macbook, ONLY between MacBook Pro and iMac when attempting to copy by dragging, or by copy and paste, over the same network (all 3 machines are within a few meters of each other).

I've tried Restarting and Restarting with PRAM, on both machines. Stopping and Starting Airport. Tried with .jpg files as well as the .rtf files. Repaired Permissions. All to no avail. I put the rtf file onto a USB drive and then I can transfer from machine to machine without any problem - it just refuses to do so over the network.

Anyone know of a solution to this?

    Have you tried saving it into a different location (like documents folder)? If this don't work, make a new user on the system that you want to copy to, and see if it still happens. Either which way, post up your results from it, please

    On the MBP, launch the Keychain Access application in any of the following ways:

    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

    ☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

    ☞ Open LaunchPad. Click Utilities, then Keychain Access in the icon grid.

      
    Enter the term "afp" (without the quotes) in the search box in the toolbar of the Keychain Access window. You should find one or more items of the kind "network password" with the Bonjour name of the iMac. Delete those items. Quit Keychain Access.
       
    Unmount the network volume if it's mounted, then remount it. You'll be prompted for a user name and password. Enter the credentials of the user on the iMac who is the owner of the files. Test.

    I'm struggling to understand what this means. Are you referring to Screen Sharing, File Sharing, or both?

    OK, that shows what you can't do, but I still don't understand this:

     

    I can drag a file, via the MBP Finder, from the iMAC Desktop to the MBP Desktop directly, correctly and with no hassle.

    What do you mean by "directly?"

  • Linc Davis Level 10 Level 10 (107,770 points)

    Maybe I'm completely failing to understand you, but you seem to be saying that there is (a) one way in which you can copy files from one computer to the other, and (b) another way in which you can't. I'm pretty sure I understand what (b) is, but I have no idea what (a) is. Maybe another set of screenshots would help.

    Launch the Console application in any of the following ways:

     

    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

     

    ☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

     

    ☞ Open LaunchPad. Click Utilities, then Console in the icon grid.

     

    Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select

    View Show Log List

    from the menu bar.

     

    Click the Clear Display icon in the toolbar. Then try the action that you're having trouble with again. Select any messages that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message (command-V).

    When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.

    Please do not indiscriminately dump thousands of lines from the log into this discussion.

    Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
