I tried to install Ubuntu on my MacbookPro (mid 2015, OS X Yosemite) dual boot, using the following: How to Dual-Boot OS X and Ubuntu (PDF)

I was finishing up part 3 and Ubuntu was starting to download, until everything froze. Nothing was responding so I force shutdown my computer and now OS X seems to be working fine. However I have a partition disk0s3 (Linux Swap) and a bunch of Free Space I can't get rid of.

#:                       TYPE NAME                    SIZE       IDENTIFIER
0:      GUID_partition_scheme                        *251.0 GB   disk0
1:                        EFI EFI                     209.7 MB   disk0s1
2:                  Apple_HFS Macintosh HD            182.6 GB   disk0s2
3:                 Linux Swap                         16.4 GB    disk0s3

I tried getting rid of them through Internet Recovery but that didn't work either. How can I get rid of the partition and the Free Space?


If you are using El Capitan (OS X 10.11), then the document you are referencing will not work as expected.

As for your question. The command below will remove the Linux Swap partition.

sudo diskutil erasevolume "Free Space" "" /dev/disk0s3

The next command expands your Macintosh HD volume to contain the free space.

sudo diskutil resizevolume /dev/disk0s2 R

Note: I am not sure if the prefix sudo is necessary. (But, it will do no harm if you include the sudo)

  • The first command didn't work (something about not being able to find that partition) but the second command got rid of the Free Space. – noobProgrammer Aug 6 '16 at 17:36
  • What version of OS X are you using? Yosemite (OS X 10.10) will generate an error message when the first command is used, but the command still removes the partition. – David Anderson Aug 6 '16 at 17:39
  1. Try: open Disk Utility, select the Linux Swap partition, in the toolbar there should be a delete disk option, try that, and try to remove the partition.

  2. If 1 didn't work, try use First Aid in Disk Utility (first on the partition and then on the main drive)

  3. If 2 didn't work, try to boot in to Recovery Mode, select Disk Utility from the menu, and try option 1 and 2 again.

  • In DiskUtility, I selected the partition and choose "Erase" at the top. But it failed with the error "MediaKit reports no such partition." – noobProgrammer Aug 6 '16 at 17:16
  • Did you try in recovery mode? – Harcker Aug 6 '16 at 17:17
  • Recovery mode wasn't able to start up. The estimated time to start kept going up. David's solution worked for me, however – noobProgrammer Aug 6 '16 at 17:35
  • You have no recovery partition to boot to. If you did, then the partition would have appeared in your posted output of the diskutil list command. – David Anderson Aug 6 '16 at 17:44
  • Actually, the OS X Recovery over the Internet keys are Command-Option-R. Other key combinations can be found at the Apple web site: Startup key combinations for Mac. – David Anderson Aug 7 '16 at 3:50
