Insufficient disk space for partition resizing on 256GB disk

If the Asahi Linux was removed properly

The diskutil list command would look much like this

/dev/disk0 (internal, physical):

   #:                       TYPE NAME                    SIZE       IDENTIFIER

   0:      GUID_partition_scheme                        *500.3 GB   disk0

   1:             Apple_APFS_ISC Container disk1         524.3 MB   disk0s1

   2:                 Apple_APFS Container disk3         494.4 GB   disk0s2

   3:        Apple_APFS_Recovery Container disk2         5.4 GB     disk0s3

/dev/disk3 (synthesized):

   #:                       TYPE NAME                    SIZE       IDENTIFIER

   0:      APFS Container Scheme -                      +494.4 GB   disk3

                                 Physical Store disk0s2

   1:                APFS Volume Macintosh HD            11.2 GB    disk3s1

   2:              APFS Snapshot com.apple.os.update-... 11.2 GB    disk3s1s1

   3:                APFS Volume Preboot                 6.9 GB     disk3s2

   4:                APFS Volume Recovery                1.0 GB     disk3s3

   5:                APFS Volume Data                    28.6 GB    disk3s5

   6:                APFS Volume VM                      20.5 KB    disk3s6

Right Now >>

There is an unexpected

3:       Microsoft Basic Data EFI - FEDOR             523.2 MB   disk0s5

                    (free space)     178.7 GB  

How you are going to get this right

Personally, I would wait for someone who can offer that solution

Outside of that

You can use the information my other post here as a guide to remove all the Linux partitions, then merge the "(free space)" back into the APFS Container currently listed in your screenshot as "disk0s2". I may have had one earlier post in that thread as well you may want to reference.

Delete Linux Partitions & Merge free space -- HWTech - Apple Community

Edit: FYI, it is usually best to review the removal procedures prior to installing or modifying a system so you are prepared with everything you need. I believe the Asahi team just expects a user to perform a DFU Firmware Restore to reset the Mac & push a clean copy of macOS onto the internal SSD followed by restoring from a backup. In my own personal experience it is usually easier to modify a system then to undo those modifications regardless what those modifications are.

I think you need to delete the EFI FEDOR Partition making it free space. Then, you may be able to expand Macintosh HD into that combined free space.

There is a similar post from a couple of months ago that solved the same issue, but I cannot find it.

As you may have noticed and are now experiencing

Apple Silicon computers are far more complex to FIX one a Third Party Operating System has been installed and altered to Original Drive Structure

Something to consider carefully before going down this road again.

Good luck

Please run this Terminal command to see all the partitions on this drive

diskutil list

The, post back the results

What is on the partition before it? It appears you partitioned the drive and installed macOS on the second partition.
