The problem is NOT an Apple/Mac issue. EVERY other app I use on a daily basis has seamlessly worked with the Sonoma OS update.  Do a simple Google search and you will see that this is the case. 

Intuit/QBO has not done their job to provide a product that works on the OS and has taken no ownership of the issue, thereby failing to serve its paying customers.  Stop blaming Apple/Mac and fix the issue!
