So i'm trying to resize a partition on my backup drive without erasing my data (see here).

I have been talking to some of my friends about this since my other question currently has no responses, and one of them recommended I use another program. So therefore i'd like to ask, are there any programs that:

  • work on Mac OS X El Capitan
  • are free
  • I can use as an alternative to Disk Utility (since its not working) to resize the partition on my backup drive.
  • I'm ideally looking for one that i can run on just my user without requiring admin permissions to install or run

You could take a look at PartEd Magick:

  • Free, gratis & Open Source
  • Runs on Intel Based Systems including Intel Macs
  • No installation - you boot into the Parted Magic Linux based OS hence you need access to the hardware but not to admin passwords.
  • Supports: ext2, ext3, ext4, fat16, fat32, ntfs, reiserfs, btrfs, hfs and hfs+ plus limited support for other file systems.
  • Unfortunately it's not free anymore, you can download the last free version from here
