Intuit has released version 2.8 of Quicken 2015 for Mac with fixes for an issue where the Last Downloaded filter didn’t display Quicken Connect transactions, for a bug that caused duplicates after downloading transactions that didn’t match, and for a failure to add accounts because duplicated accounts were detected. Additionally, the personal accounting software now requires a minimum of version 2.7 in order to access Connected Services such as transaction, balance, and quote download due to the addition of multi-factor authentication (referred to as Secure Login by Intuit).
Intuit has also stopped distributing Quicken 2015 for Mac updates through the Mac App Store. If you made your purchase through the Mac App Store, you’ll need to download Quicken Utility, which will install a version of Quicken 2015 for Mac that can retrieve updates without using the App Store — see this Intuit support page for details and a download link.
