Troubleshooting Extended Display Issues:

B. Open in Safe Mode:
In Safe Mode, Login Items do not run at login, certain preferences are set aside, and damaged system files are then reset. So, once booted in to Safe Mode, wait 30 seconds, and try opening it. Then boot up normally, attempting another update install. For instructions, go here: How to Use Safe Mode on your Mac - Apple Support
