I kept one computer on the older processor and tried a bunch of programs like Money and Mint etc. I went thru this back before Intuit finally fixed 2007 so it would wok on the Intel processor. Instead they take our money on these ridiculous substitutes that don't work. You would think in ten years Intuit or whoever Quicken is now would have had time to put together a program like 2007 that is 64 bit.
Yes 2007 works on Sierra but will not on High Sierra because High Sierra requires 64 bit programs.
