Yes, I had seen that site which confirms: No more Quicken 2007 support, and the day the OS doesn't work with it, I'm done. The only way out (there's nothing available in Canada except for Windows) is to enrol in a U.S. annual subscription, which is not for me.
And, even if I wanted to pay a yearly fee, Quicken doesn't even guarantee that my QIF file can be imported. They say: "If you have a data file from an older version of Quicken for Mac, you can
attempt to convert the file to the latest Mac version."
I remain interested to learn what other folks have moved to.
