Standard

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

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

Standard

No-ScreenSharing

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

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