There is a difference.
All the major tax programs work with Lion.
iBank works with Lion and many moved from Quicken 2007 to iBank.
2007 is a workable program but will not run on OSX. So, I had to revert back to Snow Leopard. But now, I cannot use Cloud. Bummer. There is a Quicken 2010 version that will but it is lame. It won't transfer all my data from 1993 and is difficult to manipulate manually; it wants to download everything from Vanguard, Fidelity, et al. I am thinking of running two separate computers to accommodate. Anybody know another tax program that works like the 2007 version.
