If you've already launched QB and it's asking you to update, force quit the application (command-option-escape). There's an angry lynch mob currently marching on the Intuit and Apple boards and I expect it to grow as people come into work this morning and launch QB. Luckily I dodn't lose anything from my desktop because I use NoodleSoft's excellent Hazel (US$22, free trial, review), a great little application that moves all the crap that ends up on my desktop. I was a little miffed when it told me that I didn't have enough room to download the 100kb update as I have over 100GB free on my hard drive. I was doing some end-of-year accounting in QuickBooks 2006 for Mac over the weekend and received the software update notice (didn't grab a screen shot). An apparent bug in the software update code causes the accounting software to throw a vague 'you don't have enough memory' dialog after attempting to download a 100k update while it simultaneously deletes your desktop folder.
If you use QuickBooks 2006 or 2007 for the Mac– don't launch it.
