If you need to know everything about your Mac at the touch of a button, Horse Menu is an amazingly informative utility. It provides a systemwide, customizable menu that includes detailed information about your Mac’s hardware, network interfaces, memory use, graphics cards, USB and FireWire devices, mounted volumes, loaded kernel extensions, and even connected UPS devices. It also lets you control all running processes, including force-quitting misbehaving apps and setting application priorities. Finally, Horse Menu provides quick access to system logs, individual System Preference panes, and common system utilities. One of those utilities is OS X’s Apple System Profiler, which, ironically, you may never need to open again.
