EC2 Mac Metal EBS Root Volume

Question

Hello!  
  
I'm spinning up a new mac metal instance and am having problems with the root disk size.  I change the root size to 100GB when I setup the instance, but the OS is installed to an external drive with only 32GB of space (11GB is free space).  Does anyone have ideas on how to resolve this?  Installing just the basic Xcode software and pre-requisites fills up this external drive that the OS is installed to.  
  
Thank you in advance!

Answer

Thank you for reaching out. Once you have increased the size of the EBS volume on your Mac1 instance, you can execute following commands within macOS guest to increase the size of your APFS container.  
  
# Copy and paste the first three lines  
PDISK=$(diskutil list physical external | head -n1 | cut -d" " -f1)  
APFSCONT=$(diskutil list physical external | grep "Apple_APFS" | tr -s " " | cut -d" " -f8)  
sudo diskutil repairDisk $PDISK  
# Accept the prompt with "y", then paste this command  
sudo diskutil apfs resizeContainer $APFSCONT 0  
  
Since the EBS volume was resized after boot, an instance reboot is required before the additional disk size is available for your use.  
  
We are also updating our documentation to reflect this use-case and appreciate your feedback here.

Thank you SO much; this worked great!

It seems like this has still not been added to the docs anywhere, I had to search the forums for it.

Here is a copy of the output from diskutil; I can't seem to expand any of the containers, partitions, etc.

Answer

It´s interesting that you have to update the documentation only after customers ask for "this usecase". The usecase of using XCode to develop iOS apps is the main use case you are advertising on your website! Now many users are fiddling around with this trying to make it work and wasting money because they trusted the advertisement on the website.
