Yes..
This is an issue when using Qt 4.6 on the mac.
It was either a beep with 4.6 or a complete freeze using 4.7, take your pick :)

Qt is still rather buggy unfortunately, I will try doing a build
against Qt 4.8 today, this unfortunately takes a while as Qt 4.8 is
only available in 64 bits packages and there are still people using 32
bits mac..

With the bug above, you can pretty much enter and complete one setting
menu at at time. Once you have saved, you can't go anywhere with the
keyboard and you can only use the mouse.
You must quit and restart for it to work.

Having said that, you configure in one go your mac mini to enjoy VDA decoding:
Setup -> TV Settings -> Playback

select Add New
name it to whatever you like

Then click on: Add New Entry
Set it as follow:
Match Criteria: > W: 0 H: 0
Decoder: vda  Max CPU: 2
Video renderer: OpenGL, osd renderer: opengl2
Next til you get to Finish

Restart mythfrontend.. enjoy.

I will be creating an automatic entry with all profile set today
