I updated to Sonoma 14.1 today 10/25/23 and thankfully my QB 2019 seems to be working. I haven't tried every activity but I can at least open companies, write checks, and make deposits.Thank you Apple for making the fixes. Absolutely no thanks to Intuit. I will continue to use my QB 2019 for the time being but I am definitely going to explore some other personal finance software that is not Intuit because they just aren't into customer service.
