With my prior suite (9.63 and JSS 9.63) I am able to recon. Pre 10.11 computers, but not 10.11. When I use the 9.92 Suite I can't recon anything.
Is an update of the JSS necessary for Suite 9.92? I don't want to update the JSS and lose my ability to work with pre-10.11.
The errors I get are ... jamf binary failed to install, and or messages about "failed to update inventory"
You will need to upgrade your JSS to at least v9.8 to be able to manage El Capitan machines.
All Casper Suite apps (Recon, Imaging, Admin, etc) will need to be on the same version.
On a side note, Casper Imaging will need to be upgraded on your NetBoot images!
