gdisk does not show up on screen or in tools menu

[Jeff Roberts]

Hi,

I installed rEFInd on an Intel MacBook Pro 6,2 using the refind-install script. I uncommented the showtools line in refind.conf which is in /Volumes/EFI/refind. It looks like:

showtools shell, gdisk, memtest, mok_tool, apple_recovery, about, reboot, exit, firmware, fwupdate

I want to use gdisk to resize the MacOS paritiion and create a partition for Ubuntu. However gdisk does not appear in the rEFInd menu after booting. It also doesn't appear in the tools directory. Only "gptsync_x64.efi" is present in "tools". Is there an installation option that I missed?

I checked the discussion forums here and Rod's documentation on http://www.rodsbooks.com/refind/installing.html, but didn't find an answer. Any help is appreciated.

That's because gdisk is a separate program. See its project page:

https://sourceforge.net/projects/gptfdisk/

Note that gdisk can create, delete, and modify partitions, but NOT the filesystems that they contain. (It also has no explicit "resize" option; to resize; you'd delete a partition and then re-create it with another size.)

To resize an OS X partition, you should use another tool, like OS X's own Disk Utility or the GParted program in most Linux distributions.
