I tried to install the app 'Duet Display' today. It was always troublesome on my Windows PC, so I was disappointed to see it wasn't working very well on my new MBP 2017 13" w/ TB as well. The installer ran fine, but upon reboot the progress bar seemed to hang. I never reached the login prompt. A macOS update was pending and was waiting for a reboot, my iPad was plugged in and the MBP was on charge.
Anyway, I proceeded to contact Duet's support email, with them telling me to boot into Safe Mode (so I can delete the file
/Library/Extensions), but my Mac won't even boot to Safe Mode; it seems to hang again. I never reached the login prompt, again. I'm thinking that reinstalling might be my only option, or removing the file manually via the Terminal in Recovery.
What are my options?
