While some statistics on computer performance may be found easily, gathering and compiling them in one place isn't an option. With iStat Pro for Mac, you can view a simple widget with all your system performance information in one place.
Available as freeware with no restrictions, iStat Pro for Mac installs quickly and launches itself in the widget menu automatically. The program has limited support and options related to readout and measurement standards, but these limitations are not unexpected because of its stated purpose. The basic interface shows data for CPU usage, available memory, device and processor temperature, and cooling fan operations, as well as battery status and other information. You also have the option to monitor the computer from your mobile device. There are additional options to directly view the computer activity monitor, allowing you to close programs taking up CPU usage and memory. The range of temperature readings, which can be displayed in Celsius, Kelvin, or Fahrenheit, includes different areas of the system: enclosure bays, the hard drive, and heat sinks. The network statistics are also useful and provide easy-to-read information on upload and download speeds and connection information.
While it may be cluttered for some people, the iStat Pro for Mac widget contains useful performance data, especially for a free program.
Stat pro is the ultimate System monitoring widget, consisting of 9 sections which can be minimized, expanded or closed. It features detailed information on CPU, memory, hard drives, IP and external IP, bandwidth, CPU temperature, battery, uptime, temperatures and fans. You'll know exactly what's going on inside your mac. Not for the feint hearted or anyone with a small screen.
What's new in this version:
Added support for monitoring Magic Mouse battery level.
Improved support for networking on recent Mac models.
This review was originally posted on VersionTracker.com. Every upgrade makes it sleeker and more efficient. This baby works and works well. It isn't resource hungry (which a good widget shouldn't be), yet gives a good range of read-outs. There is some documentation/info on the web site - but really it is very intuitive.
Very impressed by the consistent upgrades and all for free. I love the look of the interface and the range of screens you can throw up to interrogate your machine is splendid. For anyone who has not used it, download and try. Although the developer says it's only rated up to 10.5, I am running it on 10.6.2 without any hassles at all -on both a 21.5" 3.06Ghz iMac, as well as a 15" 2.53GHz Macbook Pro. I love it when a good widget comes together.
