Increase the size of an EBS volume on your Mac instance

You can increase the size of your Amazon EBS volumes on your Mac instance. For more information, see Amazon EBS Elastic Volumes in the Amazon EBS User Guide.

After you increase the size of the volume, you must increase the size of your APFS container as follows.

Make increased disk space available for use

1. Determine if a restart is required. If you resized an existing EBS volume on a running Mac instance, you must reboot the instance to make the new size available. If disk space modification was done during launch time, a reboot will not be required.

   View current status of disk sizes:

   [ec2-user ~]$  diskutil list external physical
   /dev/disk0 (external, physical):
      #:                       TYPE NAME                    SIZE       IDENTIFIER
      0:                 GUID_partition_scheme            *322.1 GB     disk0
      1:                 EFI EFI                           209.7 MB     disk0s1
      2:                 Apple_APFS Container disk2        321.9 GB     disk0s2

2. Copy and paste the following command.

   [ec2-user ~]$ PDISK=$(diskutil list physical external | head -n1 | cut -d" " -f1)
   APFSCONT=$(diskutil list physical external | grep "Apple_APFS" | tr -s " " | cut -d" " -f8)
   yes | sudo diskutil repairDisk $PDISK

3. Copy and paste the following command.

   [ec2-user ~]$ sudo diskutil apfs resizeContainer $APFSCONT 0
