This is a heads-up for anybody who uses QuickBooks for Mac. If it had been working, and suddenly died, here's the problem.

I use the 2019 version. I think that's the newest (most current) version that is a one-time purchase, rather than monthly or yearly use fee.

I have it installed on two Macs. An older Intel powered iMac at the hangar office, and a newer Apple silicon MacBook Air that I use at home. The data file is kept on iCloud, so the same file is available to me at either location.

This arrangement worked fine for several years, then just recently the MacBook Air installation stopped working. Symptom was, I could open the data file, but as soon as I tried to do anything with it, anything at all, generate a report, make an entry in any table, anything, the program would crash.

Tried everything I could think of, opened the data file and used the "verify" and "rebuild" utilities (QuickBooks indicated success), tried a restore from a backup of an older data file, nothing worked. The program still crashed as soon as I tried any operation with the data file.

Drove to the hangar, tried it on the computer there, no problem. That told me that I did not have a corrupted data file; the problem was definitely with the MacBook installation.

Back home, deleted the program from the MacBook and reinstalled. Same problem persisted.

Did a bunch of internet research and found that Apple's initial release of MacOS 14 (Sonoma) broke QuickBooks. Many people had the same problem. Intuit declared that it was Apple's fault and stated that they (Intuit) had not intention of releasing a patch to fix the problem, but stated that they had called it to Apple's attention and even told Apple what was wrong.

Apple released updates to Sonoma, which included the fix for QuickBooks. I installed the updated OS, and all is now well again.

Summary: If you are using QuickBooks for Mac and it has stopped working, don't waste your time trying to troubleshoot QuickBooks, just make sure that your installation of MacOS is up to date.

I have had a similar problem. Since I upgraded my OS on my MacBookPro to Sonoma I noticed some login issues . I have QuickBooks 2019 for Mac. Reconciling bank account I noticed the problem and it might be leap year. The reconciliation lists items from other months, duplicate items from the same months etc. The common denominator seems to be dates. I really don't want to go to the subscription online model but I may be at the point where it is the only option. This seemed to start in 2024. I have checked and the computer has the right date. Any suggestions before I commit to online? Barbara

QB for MAC should be called Quickbooks Lite. It is stripped down and unusable. I set up a Virtual Machine and run Windows 7. I have the full Professional Manufacturing version running. I use the last year that QB sold you a disk (premier 2009) vs paying them monthly fees. Never upgrade it and it runs flawlessly with ALL the features of Quickbooks. I have a 2023 MB M3 Pro with Sonoma Ios. I run 3 sets of books and personal hacking on it.

I recently got a notice from Intuit that after March of so, you will no longer be able to purchase QB Desktop, neither Mac or PC. It seems they want to force your migration to QB Online so they can collect $60 from you in perpetuity.

I use QB Mac 2016. I set up a headless Mac Mini 2011 running High Sierra. I remote to it from my newer Mac solely to run QB. That version is the last dollar that Intuit will ever get from me. If I need a different solution, it won’t be from Intuit, and it won’t be online. I’ll go buy a bunch of ledger books and do my accounting like an 11th century Venetian monk before I use an online solution.
