My iMac comes with a 500GB internal Hard drive in one partition. After using it for 3 weeks, I decided to make an additional partition today. Additional partition is very useful when you need to restore your iMac with recovery but didn’t touch on some other folders. Today I decided to partition my HDD to 2, 250GB x 2. Mac OS X has all the built-in tools to help you do that. Check out how can I do that.
- Go to Applications folder -> Utilities.
- Go to Disk Utility.
- Select the 500GB hard drive on the left menubar.
- Select Partition on the right top menubar.
- Press the small + button.
- The second partition will be created with the default name Macintosh HD 2, rename if you wish to.
- Change the partition size as you wish. The default format of the partition is Mac OS Extended (Journaled).
- Press the Partition button to confirm.
- Check your Finder and you should see the new partition Macintosh HD 2.
Enjoy your new partition in iMac. I have done mine easily. You can restart to refresh the OS.
