We're trying to confirm we use Quicken '15 and it's safe to upgrade to MacOS Sequoia - I've used Quicken since the BF introduced me to it in version '07
Then some change happened and that wouldn't work after an OS upgrade and we were forced to try a friend's copy of '15, which works but - now we're nervous about any updates/upgrades because, while not as good as '07, '15 is still the most acceptable financial management app available
