Unfortunately, data files for QuickBooks 2013 are not the same across all versions of the software, so employees using Macs and PCs can't work in the same files. On the other hand, you can "roundtrip" your company file from a Mac to a PC without losing data or information. The process involves backing up your file as a QuickBooks for Windows file and then using the Windows version of QuickBooks to restore it. This operation, while by no means impossible, is inexcusably clumsy in a world where virtually all data files are platform agnostic.
QuickBooks 2013 still has some bugs that I mentioned in my review of last year's version of the program, as well as other issues that are new to this edition. In the realm of old bugs, QuickBooks 2013 has a problem with the toolbar appearing on the screen. On my system, the toolbar occasionally appeared in the middle of the screen when I opened the program. Intuit had the same problem during its Macworld demo; the company stated that the underlying issue involved some leftover code, and indicated that it hoped to fix the problem soon.
New bugs include a couple of quirky glitches. First, clicking the check register button in the banking section did nothing, no matter how many times I clicked it. After spending some time with the program, I discovered that I had to hang my mouse over the button and select a default account before the button would work. Second, before I had an online banking account set up, the program's online account setup feature displayed a duplicate account setup dialog window that I couldn't dismiss without forcing the application to quit.
Bottom line
With each new release, Intuit improves QuickBooks for Mac. I like the 2013 version better than any previous version of the program. New import features, the option to attach external documents, and the addition of the Intuit Payment Network make this an appealing update. But toolbar bugs left over from last year and the lack of a cross-platform file format leave QuickBooks 2013 less convenient than it could and should be.
