For some reason, after using Quicken for Mac for many many years, my data file became corrupted. Rebuilding the index didn't solve the problem. I can limp along with the corrupt file, but it is damaged and Quicken doesn't have good analysis and repair utilities for fixing corrupt files or even letting you know what is corrupt in the file so you can delete and reenter transactions.

I tried to find a good backup, but the corruption snuck in before the error messages started, so my backups are also corrupt.

I looked for a decent replacement competitive product and didn't feel comfortable with the two that are emerging for the Mac market. So I bought Quicken 2008 for Windows and now run Quicken using Parallels. I hate doing this, but I need full featured financial software. I hope Quicken eventually makes a good product for the Mac, a product where you can use the data file from either Windows or OS X and a product that checks the file integrity often and gives detailed diagnostics about corruption when the corruption happens.

Migrating from OS X quicken to Windows Quicken is brutally hard. The export/import doesn't work well. Lots of issues to deal with too numerous to list here. The Quicken instructions are terrible, too. It took me 3+ days to do the migration with a lot of repetitive entry to get my 2008 data entered and full securities data entered. I'll just use Quicken for the Mac as my "history".

I think Quicken for the Mac is one of the worst maintained products and a textbook example of bad software implementation.

If only there was a good, full featured alternative!
