Error -6123, 0 when upgrading or opening company file

Is there a way to display the company name/title when I open a new quickbook company file? I have several company files and when I switch company files, it doesn't tell me what file I am in. This is for the QB desktop for Mac.

Error -6123, 0 when upgrading or opening company file

Hello there, @Benito.


Thanks for letting us resolve your concern. I can help you get past the error -6123, 0 when upgrading or opening a company file and also fix the QuickBooks unexpected behavior.


If you have a company file of any size, QuickBooks for Mac is handling a lot of data. If you don’t see the data you expect or in the way you expect it, try the troubleshooting steps below and you can soon be back to the way things were.


Solution 1: Check your version of QuickBooks for Mac and your Mac’s operating system. 


Have you recently upgraded your Mac OS? That change alone can cause an older version of QuickBooks to behave differently. When you modernize your operating system, you should do the same with QuickBooks. 


You can download a trial version that will work for 30 days from you may also check out this article for QuickBooks Desktop Mac installation and set up:


Solution 2: If updating QuickBooks doesn’t fix the wonky behavior, it means version compatibility isn’t the issue. Try opening one of the sample company files that QuickBooks installed.


Repeat the activities that have been causing trouble in your company file. If the problems occur in the sample company file, try checking your disk permissions.


Here's how:

  1. Go to Disk Utility.
  2. Select Applications.
  3. Choose Utilities.
  4. Then, Disk Utility.
  5. Select your Mac’s hard drive and click the Repair Disk Permissions button.

The following article contains additional solution and information on this matter:

I'm here to guide you in performing some troubleshooting steps to resolve this unexpected behavior, @Grandpa Rome 3.


Let's start fixing this unexpected behavior by making sure that your QuickBooks software is updated to the latest version. This ensures that the program displays the latest features and resolve issues such as crashing updating your default statement email template. Here's how:

  1. Open the QuickBooks drop-down menu.
  2. Select Check for QuickBooks Updates.
  3. On the prompt window, click Install Update.
  4. Hit Install and Relaunch.

If the issue persists, you can run the Verify and Rebuild Utility tool. It is a built-in QuickBooks tool that can auto-detect and auto-resolve data-related issues within your company file. Then, the Rebuild tool will self-resolve it. Here's how:

  1. Click File.
  2. Choose Utilities.
  3. Select Verify Data.
  4. If a problem is detected:
    1. Go to File.
    2. Select Utilities. 
    3. Choose Rebuild Data.
    4. Run the Verify Data from step 1 one more time.
    5. If it still fails, restore a backup or contact technical support.

Once completed, let's make sure to reboot your device to ensure that all components are updated. You can read through this article for more detailed instructions about fixing issues when using QuickBooks: Troubleshoot Crash Catcher.
