Functions as advertised on Yosemite & Mac Pro 3,1

It runs. It shows the menu bar icons and such. It updates. System shows now additional load or slow-down thus far. Freeing memory takes longer than some other apps, but it works properly in Yosemite... unlike some other apps Ive tried.

I would give 5 stars for more menubar icon options - vertical bar, pie chart, memory usage history graph, etc. But in that it does exactly what you see in the description of the app, it certainly deserves its four stars. If we could do half stars, I would rate it 4.5.
