I tried using Quicken Classic for Mac (current OS). When I created and imported the .qif file from Banktivity and imported it to Quicken, some of my accounts were way off. I discovered that many "transfer" transactions in Banktivity (such as a loan payment) were duplicated in Quicken which resulted in a huge disparity in my bank balance in Quicken.
Quicken help line was of no help. Told be to go back and manually delete (hundreds) of duplicate transactions. Nope.
Any ideas.
