I use a wireless mouse with my Thunderbolt display and have for several years. My mouse abruptly stopped working yesterday. I've tried it with 2 other "mice", including one that plugs into the USB port, and none of them work. I tried other devices in my USB ports to make sure they work and they do. What is going on? I need my large screen to work. Help?????
macOS Sierra (10.12.1)
Try safe mode if your Mac doesn't finish starting upStart up in safe mode
To start up in safe mode:
- Start or restart your Mac, then immediately press and hold the Shift key. The white Apple logo appears on your display. If you don't see the Apple logo, learn what to do.
- Release the shift key when you see the login window. If your startup disk is encrypted with FileVault, you might be asked to log in twice: once to unlock the startup disk, and again to log in to the Finder.
To leave safe mode, restart your Mac without pressing any keys during startup.
If an issue doesn't happen in safe mode
If an issue doesn't happen when your Mac is started in safe mode, try restarting without pressing any keys.
- If the issue comes back, you might have incompatible login items.
- If the issue doesn't come back, it was probably caused by a cache or directory issue with your startup disk, which safe mode fixed.
