Does the MultiTester run all the tests in TechTool Pro 3?
No. The MultiTester contains enough tests to do a reasonably thorough check of your computer. It runs these tests with settings that will do a good job of finding most common problems in a reasonable time. For more thorough checking of a particular component or subsystem you should run the tests individually directly from the Navigation window. This will allow you a wider selection of test options. Also, some functions, such as Optimization and Modem test, are only available from the Navigation window.
