Downloaded and installed the "combo" package without incident. This update resolved an ongoing issue (several months) with having difficulty getting "clean" shutdowns of my 2007 15" MBP. Had tried numerous options of shutting down background programs, deleting Safari cache's and history, removing Safari from the dock and then opening from the Application Folder, and on and on without any consistent solution. The problem appeared to be traceable to something in Safari. NOW all is well. I don't have to do any of the things I tried. Just click on "Shut down" and it SHUTS DOWN. Imagine that. Good work by Apple providing a real update.

I said goodbye to Intuit after they left us hanging with QB 2007 - MAC and forced upgrade for Snow Leopard. Look at MoneyWorks (Cognito, Inc.), especially if you're Canadian. They have an office in Canada, speak English, answer the phones promptly and get back to you with solutions, if they can't solve your problem on the spot.
MoneyWOrks is a little more "hardcore" than QB, but it's NOT buggy and runs on EITHER MAC OSX or Windows. They'll send your accountant a FREE copy, too.
Good Luck with Intuit.
