An update: Although I was able to download the "new" version of Quicken 2007 to work on OS X 10.8 (mountain lion), which presumably works on Mavericks as well, AND it resurrected all my old data several years back, Quicken started crashing at unexpected intervals. I had this issue before upgrading to a new macbook and 10.8, and it seems Quicken 2007 is simply not stable.
So, I've been test-driving iBank for about a week on a trial. I was able to bring all of my old Quicken data into iBank by pointing it to the QIF data file -- a major benefit over starting afresh with Mint online. However, the software is about $60, and if you subscribe to Direct Access, which some banks require to download your data, that's an additional subscription fee ($5 monthly or $40 annually). My main bank allows direct download using OFX, which does not require the subscription, but I have one account that only allows download via Direct Access, so I would have to pay that fee. Further, I've not been able to connect to one US Bank credit card account (a security issue that I can't seem to find a way around) and a gov't retirement account (TSP). So, I can't really have all the financials under one roof. I'm also not impressed with iBank's tracking of and handling of investments, although our needs are pretty basic.
iBank has many of the features I used in Quicken, and I've figured out how to create the reports I need -- they are not as customizable as in Quicken, however. There are also other little conveniences common to Quicken that iBank does not offer -- for example, a drop-down menu when you are filling in categories. You must begin typing and it will show only those categories starting with those letters. If you don't know what a category is called you have to go explore a separate category page.
Yet another glitch: iBank suddenly began mixing up transactions between two savings accounts, importing them into the wrong accounts. With help from the iBank chat support, I took those accounts offline and then reinstated the bank connection -- that seemed to clear up the problem, but this does not bode well for iBank's system, in my opinion.
Bottom line: I am not thrilled with iBank, although it seems to offer perhaps the best of a bad array of options for Mac users. I guess it depends which set of frustrations you want to live with: iBank, Mint, or Quicken 2007. So onward, once more into the breach...
