This is pretty amazing, thanks to a new supporter (“JC”):

I saw your you and your wife use a mac. You mentioned in one of your videos and I also saw it in the video too. I am not sure if yours is one of the core duo or core2duo chips inside of it. If it is be sure to get xslimmer. It’s a great program. What it does it removes the old powerpc code that you don’t need from the universal binary programs. I have noticed my programs start up faster, and use less ram. Also I get back lost hard drive space. The only drawback is the program costs $11.95 but I think its worth it. Sorry to waste your time if you have heard about it before.

Wicked, but does it really work?
