Hello Fran8.

For QuickBooks Mac, you can go to the QuickBooks Preferences section and update the closing date there. This way, you can edit and save the date on the transactions.

Here's how:

1. Click the QuickBooks menu above.
2. Select Preferences.
3. In the Preferences window, click Users & Password at the bottom.
4. Click the Set closing date section and edit the date there.

Please let me know how it goes. I'll be right here if you're still unable to create transactions or edit the dates.
