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.

NBI’s for 10.7.x – 10.11.1 work fine over ARD or VNC with that option selected, so some investigation was needed. Below is the investigative work, but you can also skip straight to the resolution.

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.

On the flight to JNUC2015 I loaded up my 10.11 GM VM & figured it out.

10.8 Clients Not Connecting To EAP-TLS Wireless With w2k8 NPS


Earlier today we started to tighten up one of our wireless networks, moving from PEAP to EAP-TLS authentication. In testing on 10.9.x & win7 clients, all worked well. But when deploying the same config profile that connected the 10.9.x clients to a 10.8.x Mac, the device failed to authenticate.

The 10.8.x clients console log didn’t show much information, so I took a look on the NPS servers logs (which are not a pretty sight) & after a time we came to a solution.

See below for the gory details.

Our users authenticate to the wireless using their AD credentials, after a password change they should be prompted to enter their new password. Once done they should reconnect to the wireless.
