Expanding partition size in an ESXi-hosted macOS VM

April 9, 2017 Leave a comment

As part of working on a project recently, I ran into an unexpected problem with ESXi-hosted Mac VMs. For these VMs, I was creating VMDK files from AutoDMG-generated disk images, using vfuse to convert the disk image into a VM with ESXi-compatible VMDK disk image files.

My workflow looked like this:

1. Create disk image using AutoDMG.
2. Use vfuse to create VMDK files using a command similar to the one shown below:

sudo vfuse -i /path/to/autodmg_created_disk_image_here --esx

3. Upload the VMDK files to a convenient location on my ESXi server
4. Set up a new VM, using copies of uploaded VMDK files for the VM boot disk.
5. Resize the new VM to the desired size using VMware’s vmkfstools utility.
6. Start up the VM.

After logging in, I ran the following command to enable macOS to recognize and use the unallocated space from the VM resizing:

diskutil resizeVolume / R

Normally, this command is able to do a live re-sizing of the boot partition to use all available unallocated space. However, this time the re-sizing process failed and the following error was displayed:

Running all Jamf Pro policies in a specified category via the API

April 6, 2017 2 comments

As part of a project I’m working on, I need to run several policies from a Jamf Pro server using a script which is using the Jamf Pro agent to run policies. However, I also want to maintain maximum flexibility and retain the ability to add, remove or change policies as required without needing to change the script.

My colleague Marc provided a solution for this by letting me know that it was possible to use the Jamf Pro API to pull down a list of policies associated with a specific category and then running those policies in the order provided by the API. For more details, see below the jump.
