Thank you, CarriesMac, for revisiting this thread and taking the steps suggested by my colleague. I understand you have encountered significant hurdles while preparing your bank reconciliations, and I admire your persistence in seeking a resolution. I am here to assist you further.

The issue with the greyed-out Reconcile screen may be due to a temporary software glitch that can occur after prolonged use of QuickBooks or following system updates.

Here’s what we can do:

1. Force Quit QuickBooks: Since the standard procedures have not resolved the issue, please force quit the application by pressing Cmd + Opt + Esc, selecting QuickBooks, and then clicking Force Quit.
2. Restart Your Computer: Once QuickBooks has been closed, kindly restart your computer. It can help resolve any minor glitches causing the application to freeze.
3. Reinstall QuickBooks: After restarting, please uninstall and then reinstall QuickBooks. If dragging the app to the Trash has been unsuccessful, you might want to use a dedicated app uninstaller to ensure all associated files are removed. Reinstalling from a fresh download from the Intuit website ensures there are no corrupted files in your installation.

For more detailed guidance on uninstallation and reinstallation, refer to this article: Reinstall QuickBooks for Mac using ca lean install.
