I am a Freelance Software Developer since last 8 years. I have worked with clients all over the globe.

Basic Summary

  1. Open the "Disk Uitlity' app.
  2. Select disk
  3. Set partition format.
  4. Set partition size.
  5. Crea partition.

Steps to follow

  1. Click Launchpad
  2. Click Utilities or Other
  3. Open "Disk Utility" app
  4. Select "Machintosh HD" in internal on right hand side.
  5. Click "Partition" button located at top.
