Hello Bomber44,
Thanks for that info and for choosing the Apple Support Communities. If I understand correctly, you are unable to open Safari without the Extensions window also opening and needing to be closed first before using Safari. To help with this, please quit Safari, and then hold the Shift key while opening Safari again.
Automatically re-open windows, apps, and documents on your Mac
Next, use safe mode to start up your Mac as it does the following things:
- Verifies your startup disk and attempts to repair directory issues, if needed
- Loads only required kernel extensions
- Prevents Startup Items and Login Items from opening automatically
- Disables user-installed fonts
- Deletes font caches, kernel cache, and other system cache files
Log in to your user account and test the issue while in safe mode and then restart normally and test the issue again.
Use safe mode to isolate issues with your Mac
Graphics performance limited in macOS Recovery, safe mode, or Guest User mode
Cheers!
