I use a mac OS 10.6.7 and used tech tracker (free) two weeks ago. I upgraded many of my software through tech tracker. It still shows, everyday, that I need to update the software that is now updated, and in use. TT seems not to be able to see the downloaded updates. I've cleared the browser cache a few times. Examples are Skype, VLC Media Player, Firefox, Adobe Flash Player and Acrobat, Safari, iTunes and the list goes on and on
