The problem manifests itself by not recognizing the Lightscribe Burner.
I found a fix on this page:
https://lightscribesoftware.org/how-to-install-system-software-on-el-capitan/
…followed it step-by-step and it brought my burner back to life, phew!
The cause is the SIP (system integrity protection) enabled.
The Solution…
To disable follow these steps:
- Boot to Recovery OS by restarting your machine and holding down the Command and R keys at startup.
- Launch Terminal from the Utilities menu.
- Enter the following command: csrutil disable
- Reboot your computer.
- Download newest Lightscribe Host software; expand the .tar file on the desktop
- Install Pacifist 3.5.7 version and install the lightscribe.pkg file with Pacifist.
and don’t forget the final step, which I almost did….
- Then you can, with the terminal command “csrutil enable”, as action describe above, enable the SIP again.
