Learning from Intuit's work patterns over the years (including when Sonoma released), DO NOT upgrade your OS immediately after release. You should wait at least 2 months before considering upgrading your OS to Sequoia to run QB. I'm confident Intuit will make sure that QBD 2022-2024 support Sequioa but they will need time to release updates and make those versions stable. What about QBD 2021 or older versions? Intuit will not release any updates for outdated versions. If you're running QBD 2019-2021, I recommend staying with Sonoma until next year and keeping an eye out for any updates from other early adopters.
