Recently we updated all our instances to Jamf 10.7.1, for Mojave support.

All went well. Except for a couple of instances where their Jamf Infrastructure Manager was being used as an LDAP Proxy.

Well, turns out this was a change to Java 8 Update 181, which we updated to at the same time. And, that this is an issue not just with Jamf Infrastructure Manager, but could be with LDAPS in general.

10.11.2: Cannot Enable ARD or VNC if /Library/Application Support/Apple/Remote Desktop is missing



A issue was opened recently for AutoCasperNBI, where 10.11.2 NBI’s generated for not accessible over ARD or VNC.

Some digging revealed this this only affected NBI’s with the “Reduce Image Size” option selected.

ditto: “Operation not permitted” from SIP protected locations on El Capitan



When trying to bring 10.11 support to AutoCasperNBI & AutoImagrNBI I stumbled across an odd issue.

Below is what I found, steps to reproduce & a link to the bug on Open Radar.

Well, as detailed previously, we moved from using Software Update servers to Caching.

The move to caching servers actually meant I shot myself in the foot some & caused my own issue. JAMF Support got me things sorted & below is how & my guess work as to what was happening.
