Bluetooth not enabled at startup on MacPro 3,1
Try a PRAM reset if you think NVRAM could be causing this. Other than that you can create a new admin user in System Preferences > Users &amp; Groups and reboot into that. It won't fix the issue but if it doesn't happen you can be sure a setting or application in your profile is causing it. If it persists it could be NVRAM or even a software update.
