Sharing has stopped because another QuickBooks Server has modified the file.

how can i fix it. I only have one QB server intalled.

I have quick books multiuser for MAC.


Thanks for bringing this issue to my attention, anino.

The most possible reason regarding errors in accessing a shared company file is it could be opened in a different server. Regardless, I’ll see to it you can access the software again.

In the meantime, let us apply the following troubleshooting steps to resolved multi-user issues QuickBooks for Mac:

  • Verify if QuickBooks Server is running and if the company file is shared.
    1. Click Go.
    2. Choose Applications.
    3. Double-click the QuickBooks 20XX icon.
    4. Share the file if needed:
    • If the file is listed under NOT SHARED, select the file, then Start Sharing.
    • If the file is not listed, select + to add the file.
  1. Check the Mac OS firewall settings.
      1. Click the  Apple menu at the upper left of your desktop, then select System Preferences.
      2. Choose the Security & Privacy icon, then the Firewall button.
      3. Go to the Firewall Options button.
      4. Ensure the QuickBooks Server app is set to Allow Incoming Connections.
  2. Review the file sharing permissions are set correctly on the host computer.
      1. Go to the Apple menu at the upper left of your desktop, then select System Preferences.
      2. Select the Sharing icon.
      3. Mark the File Sharing checkbox.
      4. Add the folder where the company file is stored in to Shared Folders.
        1. Select + under the Shared Folder column.
        2. Browse to the folder where the company file is located, then select Add.
      5. Under the Users column, make sure the permission is set to Read and Write for Everyone or just the specific users who will be using QuickBooks.
  3. Verify if the Bonjour service is working properly on all computers.
      1. Go to  File.
      2. Choose New Finder Window.
      3. Make sure the other computers using QuickBooks are showing in the Shared section. If the other computers are not showing, QuickBooks won't be able to share the file with those computers.
      4. Check if the following ports are open: 56565 TCP, 5297 TCP, 5298 TCP/UDP, and 5353 UDP.
  4. Test the network configuration
      1. Unplug the ethernet cable or turn off the airport.
      2. Reboot the computer.
      3. Open QuickBooks and retry enabling multi-user mode.
  5. Set up a peer-to-peer direct connection
      1. Reboot all computers.
      2. Plug each end of the cable into a computer's ethernet port.
      3. When the computers start up, the Bonjour service should allow the computers to see each other. Verify this by opening a new Finder window, then check if each computer can see the other in the Shared section.
      4. Choose one computer to be the host (requires that QuickBooks Server be installed), then open the file and enable multi-user mode (File > Enable Multi-user Mode).
      5. Open QuickBooks on the second computer. From the Shared Files section, open the company file.

    People come to QuickBooks Learn & Support for help and answers—we want to let them know that we're here to listen and share our knowledge. We do that with the style and format of our responses. Here are five guidelines:

    1. Keep it conversational. When answering questions, write like you speak. Imagine you're explaining something to a trusted friend, using simple, everyday language. Avoid jargon and technical terms when possible. When no other word will do, explain technical terms in plain English.
    2. Be clear and state the answer right up front. Ask yourself what specific information the person really needs and then provide it. Stick to the topic and avoid unnecessary details. Break information down into a numbered or bulleted list and highlight the most important details in bold.
    3. Be concise. Aim for no more than two short sentences in a paragraph, and try to keep paragraphs to two lines. A wall of text can look intimidating and many won't read it, so break it up. It's okay to link to other resources for more details, but avoid giving answers that contain little more than a link.
    4. Be a good listener. When people post very general questions, take a second to try to understand what they're really looking for. Then, provide a response that guides them to the best possible outcome.
    5. Be encouraging and positive. Look for ways to eliminate uncertainty by anticipating people's concerns. Make it apparent that we really like helping them achieve positive outcomes.
