My MacBook has been acting strange during the holidays. I wanted to run some diagnostic tests on it. There is a program called TechTool Deluxe that came with the AppleCare protection. However, I couldn’t find where I put the installation media.
A bit of googling, I found that Apple is actually offering it as a free download. All you need is your machine’s serial number. Sweet! Here is the web site.
