Ratings and Reviews
Generally does what it promises. However, with two monitors, the menu often pops up on a different monitor from the one where you click on the title bar.
Simple drop window app
Cool little app that shows all the important statistics of your Mac all in one place.
Great tool that shows me all I need to know about my Mac's performance.
With Family Sharing set up, up to six family members can use this app.
