I've been using Quicken 98 Deluxe for the Mac for about a year. It replaced two programs: MacMoney and an investment data base that I did myself using Foxpro. So far I've been pleased with Quicken's capabilities, but would rather not do business with Intuit. I find their approach to customer service unacceptable in that you must pay for each call no matter what the problem is or when it occurs. For instance, when I first started using the program, I went to specify the backup disk. Quicken does an automatic backup on shutdown. However I found that I couldn't specify the backup location. When I called Intuit to ask about this, I was told that I had to pay a service fee. A friend of mine also bought Quicken, but got a later version. His wouldn't print checks correctly. I ended up giving him a copy of my earlier version which performed correctly.So there have been "problems", but nothing too severe. As far as investments are concerned, I think Quicken does an excellent job of "managing" them, and I do a fair amount of trading.Probably one of Quicken's best features is that you can easily export Quicken data to either Turbo Tax or MacInTax personal returns. My brother-in-law has been using QuickBooks for several years and thinks highly of it. QuickBooks can also export data for tax purposes, although I am not as familiar with that application as I am with Quicken 98.I too have seen posts regarding problems with the new version. Given that the earlier version (98 for the Mac and probably 99 for the PC) do investment tracking, that might be a way to go, i.e buy the earlier version.
