I have 15 MBPs that I need to update to Mavericks. I downloaded the image from the App Store on one of the MBPs (they are all identical models, 13" Late 2011). Now, for some reason, these machines no longer have a recovery partition and thus can't use Find My Mac... Any ideas? I really don't want to have to do internet recovery to reinstall Lion, then "purchase" (free) Mavericks from the App Store on the machines manually... How can I get my USB drive installer to produce recovery partitions?
