Enter your email address below:. If you somehow timed how long it took to execute however many yeses? Just a thought. No, not really.

You can measure the ability of the OS to start processes, but its not a measure of anything useful. I saw this elsewhere sometime ago, and wondered then what kind of practical application this could have. There are other programs that have similar prompting behaviour. I think yes dates back to Unix Edition 6. There are lots of programs that have little use by themselves but are designed specifically to be combined with something else.

Stress Test a Mac by Maxing Out CPU

Unix is Lego for computers. I did this at University, I wrote a command that spawned itself twice. I managed to bring down one of the main University servers before I had a chance to stop it. Thanks, this is really useful for testing out your cpu heatsink and cooler. Start one yes process per core including hyperthreads and use something like the Temperature Monitor app to see how hot the cpu gets over time. I have a hackintosh built with an i and an aftermarket cooler, and I wanted to see how it performed.

I just tested my macbook pro retina.

My computer has a fluttery fan and I was trying to see if revving them up might A. Fix it or B. Tell me which one is the culprit. Apple could not tell me the OS X version it shipped with. I was closer to knowing by use of online Lookup service of the serial number from invoice than their Experts. Anyway, I have a week to ship it back or to to their only Store in my state to hand it over for re-credit to card.

I could not get a rise out of the Store staff, the only time I was there and walked through slow. It has a practical application. I am stuck at ORD airport overnight. I have no luggage. I only have a T-shirt. A lifesaver. Sometimes you need to see what happens if computer is really suffering and has to deal with overload.

Tried installing on my iMac and got a warning that the version of the test was incompatible with my system Now using El Capitan and might damage my susytem, create a void in space, and cause Trump to win.

Will look for a newer version. Correction to my previous post, I meant the memory test for chips, not the stress test. If my comment could be posted in the proper web page, thank you.

I extended this idea to warm up my MacBook Air in the winter. I use the following script, saved as cpu. It automatically checks fan speed, and the script turns itself off when the fan reaches that speed. You can use Prime The program is designed as a collaborative effort to find prime numbers but can also be used to stress test the CPU.

Type memtest all 2 to test every bit of available RAM. Restart to get back to norma. The final core component of your Mac is the hard disk drive. The crucial component that holds all of your data. Over time these degrade and slow down.

When you load the app select the disk drive you want to test. Then select the size of file you want to write. I recommend the largest of 5GB. Hit the start button and it will test the read and write performance your your disk drive. It will keep doing this until you tell it to stop. Note, if you get an error saying it cannot write to the disk, select your user folder or something similar.

Sometimes selecting the root of a drive causes an unwritable error message. You can save the result of the disk speed for later use. My SSD drive has only slowed by a couple of tenths of a megabyte over the last year. All of these separate tests are useful, as well as free. However, if you want some more concrete numbers and a more repeatable test I recommend you download and buy Geekbench from the App Store.

At the end it gives you a score which you can save and compare later. I recommend you close down every app since the final score can be heavily influenced by what apps are running. There are many ways to stress test your Mac. Most of the methods are free and give you good results.
