I use a Mac and for the review I did try syncing to the Mac (iCal, address book, Stickies for notes) using PocketMac. PocketMac has a driver update that you have to download for the Storm, even if you download the latest version of PocketMac itself.
In general, PocketMac for BlackBerry has always worked very well for me, including with other recent models like the Bold. The Storm was temperamental (Mac wouldn't even see it), but I did finally get it up and running. I didn't try the advanced features such as syncing to iTunes playlists, but the PIM stuff did work.
