JAMF Software has long had 0 day support for new Apple releases. The latest version of Bushel allows you to enroll El Capitan devices. Casper 9.8 also allows you to enroll devices. There are certainly going to be subsequent updates that allow us to do even more. This was a tricky one, as the jamf binary had to be moved and there were some new enrollment policies, to keep your Apple devices as secure as possible!
Bushel is SaaS, so it’s available today. Casper should be updated. You can access our installers using your My Assets page on JAMF Nation. Happy updating!
