Product Description:

SystemLoad is a diagnostic application assisting you in the detection of cooling or power supply problems with Apple Macintosh computers. The tool can put a user-definable load onto one or more processors. This can help in diagnosing the following issues:

  • problems with the cooling system or temperature sensors
  • problems with chirping noise experienced on some G5 systems and some portable computers
  • problems with battery units of portable computers

When desired, the tool can put the processor(s) under the maximum load possible, generating the highest possible temperatures and highest load on the power supply. You so can verify if all components (CPUs, sensors, cooling subsystem, power supply unit, battery unit) are working correctly when they are pushed to their design limits. No installation is required, no administrator permissions are needed, nothing is changed in the operating system.

Operating System Requirements:

This product is designed to run on the following operating systems:

  • Mac OS X 10.3
  • Mac OS X 10.2

Additional Requirements:

  • Mac OS X 10.2 or later

SystemLoad ReviewProved my problem - Version: 1.3, 3/28/2009 09:16AM PST

I just got my laptop back with a new motherboard. It had been flakey --- slowing down/ freezing/ going to sleep/other weirdness.

System load (coupled with a temperature monitoring software) was able to show a thermal failure in my system that was causing the problems ---- by loading the machine in a controlled manner.

It did not break anything --- just showed that it was already broken --- no arguing with the techies---no time wasted chasing software problems/new user creation/"clean" installs/ reformats/ etc.

I'd call it a vital one trick pony for your utility arsenal.

Point of entertaining info -- my laptop does sing/chirp. But you have to have good ears in a very quiet room with the machine cool (fans not running) to hear it. That particular feature was to prove a specific loud intermittent problem with a run of G5 machines.

Oh, yea --- the new version looks just like the older version, with a bit better doc set.

I don't want to try this in case as it's doing what intended it takes down my power supply. Not into any costly repairs because of something that was truly avoidable to begin with.

SystemLoad ReviewNot sure what to think... - Version: 1.0, 10/25/2004 12:22PM PST

I've never had this famed "chirping" processor problem, but when I run SystemLoad, i get it. Now I know why people complain so much about it. When I set the load to anything below about 85% it chirps. Above that I get nothing. Now this is with processor performance set to automatic and nap enabled. In this configuration, the scale thing does nothing. However, when i change the processor performance to high, the scale thing is really freaky; it actually makes an eerie sounding, though quiet, scale from the power supply. I just can't imagine what this guy was thinking when he did this. I can't decide whether this is genius or absolute stupidity. Either way, bravo!
