WL7 Mac Lion 64bit version?

Greetings,

On the compatibility page I see that WL7 for mac is available in 64bit but perhaps at the time I installed it on my MacBook Pro Retina Mac OSX Lion it was 32bit, how do I go about obtaining the 64bit version?

Thanks,

Both versions are installed. To switch to 64 bit, make this choice from the “Get Info” dialog of the Finder for WaveLab.app

Sneaky, thanks!

The option to open low resolution is checked and greyed out. Is it possible to change this to unchecked to take advantage of the retina display? I’ve unlocked the padlock on the lower right, still greyed.

Thanks again,
