Can Banktivity 6 import my data from Quicken?

Yes, it is fairly easy to transfer data from Quicken to Banktivity. The first step is to export your accounts from Quicken in QIF or QMTF file format (please export all accounts in a single QIF/QMTF file). Then use the QIF/QMTF file to import your data into Banktivity on your Mac.  Transferring data from Quicken to Banktivity is covered in detail in the Getting Started section of the Banktivity 6 user manual:
