Un-partition the Hard Drives

I admit it, I made a big mistake, I partitioned my Hard Drive on my MacBook Air some tears ago! I won't ever do that again, so how do I unpartition it now? I know it might mean restoring factory settings but that's fine as I usually only use it for as a capturing device when shooting client's projects.


Any help you can offer will be gratefully received, thank you.

Thanks for posting that. It looks like there’s another partition named “Photo HD”, located directly between your main APFS Container and the “Client’s Work HD” partition.


In order to give more space to Macintosh HD, you’ll need to first destroy “Photo HD”, and then destroy “Client’s Work HD”. I recommend doing the following:


  1. Copy ALL data in “Photo HD” onto an external drive. Back up any data you want to keep from “Client’s Work HD” as well.
  2. If desired, encrypt both “Photo HD” and “Client’s Work HD”. This ensures that a disk recovery application can’t recover the files should your Mac be stolen or lost in the future.
  3. Open Disk Utility, located in Applications -> Utilities -> Disk Utility.
  4. Select Macintosh HD, then click the Partition button. When prompted, click Partition.
  5. Select “Photo HD” in the pie chart, and click the (-) button. It should disappear from the pie chart, and the APFS Container should get slightly larger.
  6. Select “Client’s Work HD” in the pie chart, and click the (-) button. It should also disappear from the pie chart. At this point, the APFS Container should fill up the entire pie chart.
  7. Click Apply, and review the changes you’re about to make. Click Continue to delete both “Photo HD” and “Client’s Work HD”, and grow Macintosh HD to full size.
  8. Wait for the partitioning process to complete. Do not power off or restart your Mac until the process is complete.
  9. If successful, the APFS Container should be full size, and you should have 40 GB of extra free space.

Hi there,


sorry but it’s an internal SSD and I partitioned it into 3!


Basically I’m trying to unpartition my partitioned MacBook SSD 2013


what I’m trying to do is download Big Sur but I’ve only got about 6 or 7 GB on ‘MAC HD’ but I’ve got 30GB free in the partition that I’ve called Clients Work, which I’m trying to give back to MAC HD.


i hope I haven’t confused things further!
