After more than 20 years using QB,  I downloaded Ventura on my iMac with desktop 2021.  It started crashing continually.  I finally called  QB.  I was required to purchase support to resolve the issue.  They spent a couple of hours trying to figure it out, concluding I needed to upgrade to desktop 2023.  After another hour or so (during my busy work day), after the 2023 was paid for and installed, the constant crashes continued.  I was told that I needed to report the problem to Apple and go back to the Monterey operating system.  A ridiculous recommendation.  I assumed others were experiencing the same problem.  Frequent crashes continue, and I continue to report them to QB and Apple.  QB tells me they are working on it but may never resolve the problem.  Very time consuming and disastrous for my business.
