Got a new MBP with SSD. I recently moved to using Aperture importing my pictures into Aperture. The amount of data was roughly 125Gb. After I got comfortable with everything I deleted the actual files on my HD. If you go to About This Mac, More Info, Storage, it does not reflect this new 125Gb of free space. If you right-click on the SSD in Finder, the space Available does look accurate. Does About This Mac only update periodically?
