None of the Intuit employees on this site will give you any assurance of the functionality of QB 2021 on your computer. I also do not process payroll or use any import features. It worked perfectly for me on Sonoma and continues to work perfectly for me on Sequoia 15.1.1. If you are hesitant, open your QB, check for updates, and update if any are available. Next, do a Time Machine backup of your Mac on an external drive and then disconnect the drive. Update your OS to Sonoma, open QB, and check for updates again. Finally, open QB and see if it is working for you. If it is not, restore your Time Machine backup to your Mac to revert to the previous state.
