As a Mac user, my initial concern was how well Windows Phone would work with my computer. Most of my data is in the cloud in various formats, but I do occasionally want to directly access the device from one of my Macs.
Microsoft provides a Windows Phone app on the Mac App Store, which is very much like iTunes on OS X.
You can view and sync various types of data, just like the device screens in iTunes, and view a chart of what’s taking up space on your Windows Phone.
Photos and screenshots can easily be taken from the device either automatically or manually, either en masse or individually, just like in Image Capture on OS X.
