Unable to Delete Ubuntu Partition on Mac Studio (2022)

I’m experiencing an issue with my Apple Mac Studio (2022, M1 Max) related to dual partitions on the internal drive. The hard drive is split into two partitions: one for macOS and the other for Ubuntu.

Here are the challenges I’m facing:

  • I cannot access or boot into the Ubuntu partition.
  • In macOS, the Ubuntu partition does not appear, even when I select "Show All Devices" in Disk Utility.
  • In recovery mode, I’ve tried erasing the entire drive and reloading macOS, but the dual partition persists every time.
  • When I attempt to partition the drive in Disk Utility, the option to delete the Ubuntu partition is unavailable.

This device was handed down to me, and the previous owner faced similar issues after the employee who initially set it up left the company.

I’d greatly appreciate any advice on how to completely remove the Ubuntu partition and merge it with the macOS partition to restore full storage capacity. Please excuse the camera images I’ve included—I found it easier than taking screenshots from within the OS.

Thanks in advance for the help!

Mac Studio, macOS 15.2

I can't quote from your posting without re-capturing a screenshot of your screenshot. A copy of the text, rather that a picture of the text, would have been more helpful.


disk0s3 is is not inside the Container-disk, so it should be re-sizaeble or removable.


"The preceding volume" referenced is that 2.1GB Linux volume. Can it be resized downward or removed?

Yes, that is the correct diskutil command to use to delete these partitions.


Assuming the next goal is to expand the existing partition disk0s2 (which would be the primary partition) into the free space that you just created, you would use a command like: diskutil resizeVolume disk0s2 0


Note: The 0 at the end tells macOS to expand the partition to use all available free space.


Regardless, always be very careful when using these commands ... unless you don't care about anything on the Mac's drive.

Hi Grant,


Apologies for the screen grab, here is a copy of the text. I will work on confirming if I can resize or remove the Linux volume, but IIRC I was not able to do so from the Disk Utility last time I tried. Will follow up shortly.

I am wiping the device, so the contents of drive are unimportant.


I was able to complete the suggestion using a slightly different command, but here are my results:


-bash-3.2# diskutil list

/dev/disk0 (internal, physical):

   0:    GUID_partition_scheme             *500.3 GB   disk0

   2:          Apple_APFS Container disk3      494.4 GB   disk0s2

   3:     Apple_APFS_Recovery Container disk2      5.4 GB    disk0s5


/dev/disk3 (synthesized):

   #:             TYPE NAME           SIZE     IDENTIFIER
