I have tweeted to  @AlexGBalazs and @sasangoodarzi, Intuit's EVP of Development and their CEO.  I let them know that I would like to see a patch for QB Mac 2019 and am willing to pay for the patch, although that should not be necessary as Intuit knew ahead of the launch that Mac QB Desktop apps would crash. Or, they should have known as they had the Beta Sonoma OS from Apple up until the announced official release date and knew that that all their Mac Desktop software including their latest versions did not work and would crash.  (I am assuming all versions of MacDesk Top software was being tested and they found that all versions had some sort of problems. They talked about having to patch 2024.)  They should have known this and communicated this problem to their clients.  This as an Intuit problem for not notifying clients in advance that their Mac Desktop users should not upgrade.  They certainly have the means to notify me when there is a new product that they want me to buy, so I am sure they could have given me a heads up.  I am very disappointed that they are not stepping up and offering a patch/s for 2019 and versions forward.  This software is less than four years old and should not be sunsetted so quickly.   Intuit needs to do the right thing for it's clients.  QB Mac 2019 does everything I need it to do and I do not want to be forced to remain on an older OS because they will not allocate some engineering resources to keep the product compatible with OS upgrades.  I am not asking for new features, just a reasonable update to work on a new OS.
