Quicken Classic Version 9.1.1 (Build 901.61363.100) MacOS 26.6
I used the Windows version for MANY years while I waited for Intuit to improve the Mac version. Then "you" bought Quicken from them and improved the Mac version! You've done good work!
I REALLY miss the ability to forecast tax liability, seems like it was called Tax Planner. There was a section in the Windows version where you could modify each taxable category, ex. budget, previous year, running total. At the end, you could project the tax amount due! It was GREAT and I miss it! PLEASE import that code section. (Yeah, I know its not quite that easy, but the logic is already proven ellipsis now for the Mac specific code!)
