OS X Updates In Self Service

Contributor III

I'm working out and testing doing OS upgrades through Self Service with cached packages. Of course my curiosity was sparked when watching the process.

There is a first stage of the process that takes a few minutes. Is this process just creating the Recovery Partition? Is anything else happening?

I assume you are talking about the procedures outlined in http://resources.jamfsoftware.com/archive/Deploying-OS-X-v10.7-or-Later-with-the-Casper-Suite.pdf?

Lot of things happen, including creating or updating the Recovery Partition. You can look in the system.log and installer.log files in /var/log for more information.

On a tangent note, Mike Boylan wrote an excellent analysis of the InstallESD file. You can read it at https://www.afp548.com/2012/05/30/understanding-installesd-recovery-hd-internet-recovery/
