Best app to switch between all open windows After 4 years of being a Mac user, there is only one thing that I still miss from the Windows world, and that is being able to switch with a single keystroke between all open windows in the computer.

What is the best app or utility, free or not, for accomplishing that?

I've used Witch, but I never was completely satisfied with it. It's a bit slow and the switcher UI is not very pretty.

Do you know any alternative?



EDIT (2016): This question keeps getting views and upvotes after 6 years. When I asked this question in 2010 I was still transitioning from being a Windows user. Eventually, I got used to Mac OS X UI and nowadays I don't use any third party utility for managing app windows, just Mission Control and the native keyboard shortcuts. So, although this question is no longer relevant for me I hope it is useful to new Mac users making the switch (Including this comment).
Hyperswitch is free and works well. It also looks nice.
Update: ...but unfortunately as of May 2021 the app is not being updated anymore and has no native Apple Silicon (M1) support.
