I thought 5 was pretty hopeless, as it was so slloowww, but this version cranks right along. Even paid my upgrade fee, as I'm confident they got it right (the fact that it was under $6 didn't hurt). It still MAY be a tad slower than 4, but it's so negligible that I might be imagining that. So, if the first pass at 5 got you down, give this one a try. There are a slew of apps that do this type of maintenance, but this seems to be the first to address Snow Leopard. Good show, guys. Now all I need to do is find out why all the developers who've done updates for S.L — or it might be the staff at VersionTracker — continue to show the S.L. apps' operating system requirements as only up to 10.5. If it's been updated for Snow Leopard, shouldn't 10.6 be added to the list?
