Good morning, @comoltd. 

I appreciate you coming back on this thread and letting us know how these steps worked for you. 

Since those instructions didn't work, I recommend performing a reinstall on your QuickBooks for Mac using clean install. Here's how: 

1. Uninstall QuickBooks Mac Desktop
2. Remove QuickBooks PLIST files. 
3. Restart your device. 
4. Reinstall QuickBooks. 

For more details on how to do these steps, check out this guide: Reinstall QuickBooks for Mac using clean install. If this doesn't work, I suggest contact our Customer Support Team for further assistance. 

I hope this helps. Reach back out and let us know how the everything goes. Have a wonderful day!
