This is a great list with some nice stuff for Mac as well.
18 Tools I use as a Designer & Blogger | Fuel Your Creativity:
"I’m always sharing what tools are useful to me via Twitter, but just incase you don’t use it - I wanted to share here! I always get asked what productivity tools and apps I use on a regular basis and I pretty much open all of these everyday. There are a few apps that are similar in type because some may be all in one tools or I’m just starting to use one more than the other. Check these out, they are ones I would recommend to a designer/blogger/creative type. If there is something missing from the list that you think should be on here, please share in the comments!"
