NovaBench will assess your Mac’s performance, and it doesn’t cost a penny The test takes just a few minutes to run and checks such metrics as floating point, integer and 3D graphics performance. NovaBench is a superb free app which produces detailed performance information in addition to an overall score, which can also be submitted to the NovaBench website. GeekBench is one of the most popular benchmarking apps 2. For example, floating point, integer, and memory performance. Links: Mac App Store, Primate Labs websiteĪlthough it’s not free, GeekBench does provide a comprehensive suite of performance and benchmarking tests to see how your Mac really performs. Here are just a few of those apps, but there are many more on the App Store. The advantage of such apps is that you’ll also get an overall performance score, which you can compare with other users and machines. There are many apps in the App Store which can benchmark and stress your computer to the limit. Once CPULed is installed, you can easily check on your CPU load from the menu bar: Green icons means your CPU is not being taxed much Benchmarking Apps It has a few simple preferences (and paid-for add-ons) and you can also choose the desired CPU meter icons from an extensive list of attractive options Keep an eye on your CPU load at all times There are also a few free apps on the App Store such as CPULed which sits unobtrusively in your main menu bar and displays the CPU activity – without needing to keep Activity Monitor always open. Once you have MagicanPaster installed, you can see the temperature go off the scale the Terminal commands are running: Temperatures will rocket when the tests are running MagicanPaster has lots of controls and widgets to monitor your Mac, but it’s the temperature one that we’re interested in for now Can it take the heat? The CPU, battery, motherboard and disk temperatures are displayed, and as you run the tests in Terminal you’ll see the heat rise dramatically. To check the CPU temperature, an app such as MagicanPaster (which is available on the Mac App Store) is ideal. Activity Monitor indicates what your CPU cores are doingĦ. With the two Terminal windows still running, you can now view the CPU performance which should reach nearly 100% for each core. Click on the %CPU column header to view the list of processes in descending order of CPU time used Activity Monitor is one of the most useful Mac applications Here you can view the overall CPU load for all applications and processes, including the two “yes” commands already running. To actually view your Mac’s activity and monitor the load, open Activity Monitor (which also lives in the Utilities folder) and click on the CPU tab. If you have a dual-core machine this will load up both cores to around 100% Set two Terminal windows running the “yes” command to /dev/nullĥ. Once you’ve set one Terminal window running with the yes command, open a second Terminal window (with COMMAND + N) and type in the same command. to nowhere) without displaying any output onscreenĤ. A better way to load up your CPU fully is to type yes > /dev/null followed by Enter which will send the output of the yes command to the null device (i.e. This command will only stress one core of your CPU however and doesn’t really tell you much on its own The “yes” command will execute as fast as possibleģ. At the Terminal command prompt, type yes then hit Enter and it will constantly displays the character y on a new line. Open Terminal from the Applications -> Utilities folder or just type it’s name into Spotlight ( COMMAND + SPACE)Ģ.
