I sold my macbook pro. Now I need to wipe the HD before I send it out tomorrow. Just to make sure, is this how I do it? 1. Restart computer 2. Hold down command+r until the Recover mode comes up 3. Open disk utility 4. Click erase Hard Drive.... 5. Wait 6. Reinstall Lion, then it will be like a Brand New computer (no personal data) Missing any steps? Thanks!
