There's a lot of entries to this forum and not all are accurate. Let me recap where it stands:

1. If you are running macOS Sonoma Intuit has issued slipstream updates for QuickBooks Mac 2021, 2022, 2023 and 2024.  These are all the supported versions of QuickBooks Mac.

2. If you are running macOS Sonoma and QuickBooks Mac 2019 or 2020... these are unsupported products at this point and Intuit won't be updating them. There are a couple crashing issues with Sonoma and these versions.  Apple is fixing the bugs (yes, they are bugs in Sonoma and not in QuickBooks Mac itself) and we have seen those bug fixes working to eliminate these crashes in developer beta builds of macOS Sonoma. No one except Apple knows when these will be released as an official update to Sonoma or whether those bug fixes will ultimately make it into the release.  But my guess, which is just a guess, is that they will and it won't be very long now.

3. There can always be other bugs in Sonoma that cause issues with QuickBooks Mac (any version).  We'll find workarounds for them where we can for the supported versions of QuickBooks Mac.  If anyone encounters anything please post it under a new thread in this forum. 

For myself, I've had issues with fonts in PDFs and with printing timing out on an HP Ink Jet printer. Neither of these things is related to QuickBooks Mac but as always with a new macOS there can be bugs that impact workflows.
