IGG Software has released Banktivity 5.6.6 with a number of bug fixes for the financial app formerly known as iBank. The update now correctly reports bonds in the account overview page, fixes a bug that showed transactions for all months when clicking on amounts in the June column of the Expense Timeline report, resolves an issue with duplicate transactions in an OFX file not being screened out, fixes an outdated Web browser user agent for Citi.com, and uses HTTPS when retrieving historical prices. ($59.99 new from IGG Software and the Mac App Store, free update, 37.5 MB, release notes, 10.9+)
Can I buy, then both install & use Banktivity off-line ?
Yep. Can work offline without a problem.
