On Mac, it is not possible to download and install power iso and burn images so to do this easily, we can do it on the terminal which is faster, easier, and convenient.
Below are the steps that you need to follow to accomplish this.
1. Before plugging in the drive, you need to see the available ones on the device first. To do that, run the command
diskutil list
you should have an output that resembles this
❯ diskutil list
/dev/disk0 (internal, physical):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *500.3 GB disk0
1: EFI EFI 209.7 MB disk0s1
2: Apple_APFS Container disk1 500.1 GB disk0s2
/dev/disk1 (synthesized):
#: TYPE NAME SIZE IDENTIFIER
0: APFS Container Scheme - +500.1 GB disk1
Physical Store disk0s2
1: APFS Volume APPLE SSD SM0512G Me... 170.9 GB disk1s1
2: APFS Volume Preboot 447.3 MB disk1s2
3: APFS Volume Recovery 1.1 GB disk1s3
4: APFS Volume VM 2.1 GB disk1s4
5: APFS Volume APPLE SSD SM0512G Media 15.4 GB disk1s5
6: APFS Snapshot com.apple.os.update-... 15.4 GB disk1s5s1
/dev/disk3 (disk image):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme +6.1 GB disk3
1: Microsoft Basic Data 6.1 GB disk3s1
2: EFI ESP 5.2 MB disk3s2
3: Microsoft Basic Data 307.2 KB disk3s3
2. Insert the drive and run the command again.
❯ diskutil list
/dev/disk0 (internal, physical):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *500.3 GB disk0
1: EFI EFI 209.7 MB disk0s1
2: Apple_APFS Container disk1 500.1 GB disk0s2
/dev/disk1 (synthesized):

5: APFS Volume APPLE SSD SM0512G Media 15.4 GB disk1s5
6: APFS Snapshot com.apple.os.update-... 15.4 GB disk1s5s1
_**/dev/disk2 (external, physical):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *61.9 GB disk2
1: EFI EFI 209.7 MB disk2s1
2: Microsoft Basic Data Untitled 61.7 GB disk2s2**_
/dev/disk3 (disk image):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme +6.1 GB disk3
1: Microsoft Basic Data 6.1 GB disk3s1
2: EFI ESP 5.2 MB disk3s2
3: Microsoft Basic Data 307.2 KB disk3s3
You will notice that there is an additional disk on the list of disk. Take note of the drive since you will use it in the process. For me, the drive is /dev/disk2
3. unmount the disk to begin the process. For this, you have various commands and can try any of them if the others give you an error like
zsh: command not found: unmount
zsh: command not found: unmountDisk
or a similar error
a.
unmount /dev/disk2
b.
unmountDisk /dev/disk2
c.
diskutil unmountDisk /dev/disk2
4. After unmounting the drive, you now burn the iso file into the drive using the command
sudo dd bs=1m if=~/Users/gis/Downloads/ubuntu-24.04-desktop-amd64.iso of=/dev/rdisk2
NB: ~/Users/gis/Downloads/ubuntu-24.04-desktop-amd64.iso is the path to the image you wish to burn and /dev/rdisk2 is the drive in which you are burning it into
after running the above command, you wait for about 5 - 10 minutes then you will see a message like
5831+1 records in
5831+1 records out
6114656256 bytes transferred in 579.370318 secs (10553969 bytes/sec)
5. After completion, run the command
diskutil eject /dev/disk2
This will eject the drive from your machine. remove the drive and then insert it again.
And there we go, you now have a flash drive burnt in a mac device.
