I am running macOS Big Sur 11.5.2 and I am trying to partition my internal hard drive so I can Dual-Boot PopOS, which is a linux distro. However, I am having problems with partitioning my internal ssd.

Disk Utility says my internal hard drive can't be split. I have cleared my hard drive to have about 55 gb free and I will be clearing it further.

System Information shows this:

enter image description here

53.97 GB available of 121.12 GB

Disk Utility Shows This:

enter image description here

This container has 107.88 GB used space. Its minimum size is 121.12 GB. This container can’t be split, because the resulting containers would be too small.

It also has all the add, minus, and partition buttons disabled. I have tried recovery mode, but it shows the same thing. I need macOS for XCode and the Adobe Suite as they are not available on linux.

Sorry If I did something wrong, this is my first question on stack exchange.


@Jean_JD asked me to include the output of disk util list internal

  • @Jean_JD I added Oct 3, 2021 at 14:33
  • Also I forgot To Include, I already have linux installed on an external hard drive, I'm trying to install it on my internal rn Oct 3, 2021 at 14:34
  • What size do you want for Linux?

    120GB is barely enough space for macOS, many run out of free space and struggle to update macOS. Adobe takes a lot of space. But try selecting the container volume not the physical disk and reduce the size. In Disk Utility - View - Show all devices. Highlight the container and reduce it. Oct 3, 2021 at 15:07

In the abstract, use the resizeContainer verb with diskutil to deny some portion of of your 128 GB of space from the APFS storage and then have it exclusively accessible for EFI boot process.

You can see that this causes many people trouble later, so running a virtual Unix OS is my recommendation with a boot drive that small. U less you go bare bones on the macOS side, many people paint themselves in a corner if they aren’t ready to erase everything and restore regularly as they learn disk management.

diskutil apfs resizeContainer disk0s2 80G

The resize operation is safe and will give you an error if it can not comply with the request. If you need to grow it back to 120 that’s easy as well.

If you’re already backed up the fastest way forward is to do an erase install from recovery. Then you will have a very clean slate to carve out the majority of your space for Linux.

The above resize command could be as small as 40 GB or lower, but start with 80 and then shrink more as needed.

  • I looked at your comment on the question box thingy (I don't know what its called) and I saw the command that they ran. Should I run it in Recovery Mode or In Normal Macos? Also, Is there a chance this might mess up recovery mode? I don't have anything important in macos but I dont want to loose recovery mode. Oct 3, 2021 at 15:04
  • It’s safe to experiment with resizing containers on a live system @theamazing0 it’s the next steps that cause data loss in my experience, but getting the container the right size is safe

  • I saw your edit, I agree that its small but I only have 8gb ram so virtual would be pretty laggy. However, I am ok with going bare bones with macos, I only need a place for it to run from. I will have iMovie, Davnci, and Creative Cloud all installed on my external drive. Oct 3, 2021 at 15:09

    ok i see. I know the difference between RAM and storage, I probably just typed the comment wrong. Another person seems to have posted a gui alternative to what you posted so I'm just going to see what they mean and then I'll select a question as correct. Thank You For Helping Me Out Though!

    I followed your answer partitally, but when I ran a reinstall of macos the original problem fixed itself and I was able to use the gui, I'm going to go ahead and mark yours as correct. Oct 3, 2021 at 21:27
