Quickbooks Mac 2016 in Mojave crashing

You can disable third party extensions and such by rebooting your Mac and holding down the shift key while it reboots.  That launches the Mac in "Safe mode".  Give that a try and then launch QuickBooks. Does it still crash?  If not - the problem is some extension.

Another trick is to hold the option key down when you launch QuickBooks.  That prevents QB from automatically opening the last used company file.  Does that work?  If it does then try opening the Sample Product file.  Does that work?  If it does the problem may be with your company file itself.

Let me know here the results of those efforts and we'll continue if necessary.

I rebooted in safe mode and the issue remains. I also tried option + open QB still the same crash.

I've even gone so far as to rebuild the company file with my other user ( i created to test on quickbooks)  and sending it back to my main user and still same crash. So I'm guessing it's not the file since it works in my other (test) user.

Good work for doing the troubleshooting steps, Chag.
