• A Macintosh Plus or later running System 7 or later.
• 4MB of RAM.
• At least 8MB of disk space to run the tests. The disk tests are optimized to use 32MB of free space; however, you can run all the tests with 8 MB of free space.
In addition, you can have a hardware floating point processor. MacBench includes a test that lets you measure the performance of a hardware floating point processor if you have one. If you don't have a floating point chip, MacBench provides a software version of this test.
