Why isn't Alt-Tab working for switching windows of the same app?

Solution 1:

Option+Tab shouldn't be assigned to switching windows by default. You could've reassigned it in the Keyboard preferences:

It could also be handled by some third party app like Witch, LiteSwitch X, or Keyboard Maestro on the MacBook Pro.

Solution 2:

Try Command + ` (backtick). That is the default.

Solution 3:

Use Hyperswitch. I just stumbled on this posting now, and did some digging and found this nice "new" app.

Works well for me (basically turns your mac's application-switching into a windows-style task-switching environment <- much more intuitive especially when working w/ multiple screens/spaces).

Solution 4:

Mavericks use Command + Tab to switch between the application but if you want to cycle through the different window of same application use this: Command + Tab + DownArrow it will show all the open windows of the same application which you can select using arrow keys.
